Stepper Gear Motors

A motor is a small machine that aids in the movement of larger machines like vehicles, boats, and others of their kind. The motor is the part that is directly affected by electricity and fuel, which, in turn, helps machines function as they should. A gear motor is responsible for the functioning of gears in a car. Thus, there are two types of motors, which are a regular gear motor and stepper gear motor. They are used in different machines for a variety of purposes. In this post, we will be discussing the different types of stepper gear motors in the market and how they function.

Types of Stepper Gear Motors

Stepper gear motors, otherwise referred to as stepper motors, can be classified into two categories. The first category is according to their construction and design. In this first category, there are three types of stepper gear motors. They are;

  • Variable reluctance stepper gear motors

These are stepper gear motors whose construction features a core rotor which is made of iron material. The core rotor is attracted to the stator poles of the device. This attraction helps to provide movement through the process of reluctance that occurs between the stators and the rotor.

  • Permanent Magnet Stepper Motor

These are types of stepper gear motors that have permanent motors that are made from the magnet. The permanent rotor either repelled or attracted to the stator when the pulse is applied.

  • Hybrid Synchronous Stepper Motor

This type of stepper gear motor is designed in such a way that it features a combination of variable reluctance as well as a permanent stepper motor.

In addition to the above, other types of stepper gears are categorized according to the way the stator winds. In this category, there are two types of gear stepper motors. They are:

1. Bipolar Stepper Motor-

A bipolar stepper motor is one whose stator coils and also one that does not have a standard wire. Driving this form of stepper gear motor is different and more complex than the latter. Another characteristic feature about this product is the fact that its driving circuit cannot be designed as effortlessly as the latter. Additionally, the driving circuit requires a microcontroller which it cannot function without.

2. Unipolar Stepper Motor

This is one of the least complex types of motors to drive. For a common ground, this type of stepper gear motor uses the center tapings as well as the phase windings. The unipolar stepper motors can also be split into different types depending on their structure.

Conclusion

The difference between a stepper motor and an electric motor is the fact that an electric one is based on standard magnet science. This means that an electric motor works similarly that magnets work. Stepper motors also do not have brushes and commutators like the vase with the ordinary ones. The other difference lies in the manner in which the stator and the rotors are constructed. Another difference between the two is the way that the motors rotate. Regardless, they are both quite functional, depending on the need and the machine in question.

The Concept Of Molar Weight

by Chirag April 27, 2020
written by Chirag

Molar weight, also referred to as molar mass is the mass of a single molecule of a substance expressed in the unified atomic mass units. It is expressed in g/mol. As opposed to measuring, the molar mass is calculated because atoms of an element are far too small to measure manually. Calculating molar weight is as easy as a basic multiplication question. However, finding the basics like RAM can cause you to find the wrong answer. For this reason, MW Calculators were established.

Molar Weight

What is a Molarity weight calculator?

This is an online tool that is used to calculate molar mass. To use this tool, you just need to provide the name of the element or the compound, and the tool will proceed to find the answer automatically.

How to calculate the molar weight of an element?

  • The first step is to understand what the concept of molar mass or weight is all about. The molar mass is the weight of 1 mole of any substance when represented in grams. You also need to get the basic formula for calculating the molar weight. You can calculate the molar mass of any element by finding the product of the atomic mass and the factor used in the conversion of grams per mole of the substance.
  • The succeeding phase would be to figure out the relative atomic mass of the element in question. The term relative atomic mass refers to the average weight of a sample and all its isotopes represented in atomic units. The relative atomic mass can be found on the periodic table of elements. Normally, it is the number that is directly below the symbol of the element. Most of the time, it is presented as a whole number with decimals.
  • Now that you have the relative atomic mass, the next step is to multiply it by the constant molar mass. The constant molar mass is defined as 1 gram per mole. Thus, by finding the product of the two, you will be converting the atomic units to grams per mole.
  • For samples that are only found in molecules of two or more atoms, you have to multiply the product of the procedure mentioned above by the specific number of the atoms. For instance, Hydrogen and chlorine are made up of two atoms. This means that the resulting molar mass would have to be multiplied by two.

You can also calculate the molar mass of a compound or a solution. A compound is a sample that is made up of two or more elements. The fact that it is made up of more than one element means that the first step would be to determine the chemical formula of the compound. The chemical formula will help you determine how many atoms are these in each of the elements used to make the compound.

In the case of a compound, when calculating the molar weight, you must start by calculating for each of the elements. Follow the procedure explained above. Once you have the molar weight of each element in the compound, you can proceed to calculate the sum. The sum of the molar weights of each compound will give you the molar mass of the entire compound.

Conclusion

Calculating molar mass is pretty straight forward. The most important thing is to make sure you get the right relative atomic mass. The periodic table is designed to make this task effortless.

Analyzing The Industry Of Rapid Prototyping

by Chirag April 13, 2020
written by Chirag

3ERP refers to a Chinese-based rapid prototyping firm. It provides customers with affordable prototyping as well as manufacturing services. This is often coupled with high production quality in addition to IP protection.

Rapid Prototyping

Background Check

There is a valid reason why many businesses flock into China for their demands of rapid prototyping-cost. Just like with different kinds of manufacturing in the world, rapid prototyping happens to be cheap, thereby providing customers with significantly lower rates compared to other forms of manufacturing in different companies situated in North America and other regions.  

As of now, it is pretty evident that most business professionals in the industry seek affordable rates of manufacturing. However, the affordability of these processes in China comes with different downsides.

One ideal example given for you to understand the seriousness of the preferences is the fact that there are different outliers. However, the low cost of the rapid prototyping processes highly reflects the economic services, which may lack quality touch.

Detailed Explanation

Just as with the CNC subtractive methods, you will realize that there are certain computer-aided designs used in the manufacture of different products. The workflow process often begins with the design and creation of the geometric data as a solid 3D using the work station. You will realize there is a traditional way of doing things, and that is the conventional rapid prototyping process, which begins with the development of geometric data.

For most projects in rapid prototyping, the data has to represent a geometric model with boundary surfaces used to enclose some finite volume. The same data should have no holes to expose the interior of the material. The object needs to have its inside piece. Usually, the model seems to be valid for every point in the 3D space.

 For that reason, computers might quickly determine whether the point lies within the surface boundary.

Prototypes And Their Applications

As discussed in the earlier chapters, a prototype refers to a sample product that often serves as an example of the future model. In many cases, the term is used in different contexts, including design, electronics, as well as software programming.  

Naturally, prototyping has a way of providing specifications for the actual working system. In the design industry, prototyping offers an original specification for a reliable working system.  

Uses Of Prototypes

  • A prototype is used to assess whether a product works for its intended purpose or not
  • A prototype may be used in testing the reliability of a product.
  • It may work in the development of the scheduling of a

Final Thoughts

In conclusion, prototyping can be used to enhance the quality of specifications provided to different developers. Because unforeseen changes and discrepancies cost a lot to implement in development, the determination of the desires of the consumer can result in a product that is developed not just faster but at a lower price.

A prototype allows customers to see the actual product and interact with it. The entire process will enable customers to give better feedback.

Injection Mold

When molding, you need a machine and a mold that can meet your tastes and preferences. Working with a molding machine whose tonnage or size does not match your needs leads to poor artistry and final products that don’t match customer desires. For you to get a final solid piece that is customized correctly, you need a machine that is flexible enough to transform the melted material into dimensions. A plastic injection molding machine offers this and more. If you are shopping for a plastic injection mold, read this blog post for the best deals.

The following are the advantages of working with a plastic injection molding machine:

  • Greater control of the molding process: When working with plastic injection molding machines, enjoy greater control of the whole molding process. Therefore, you can easily incorporate all the desired intricate patterns in your final products. You can make bespoke molds with complex patterns, which come in different colors that match your tastes and preferences. Final product differentiation is easy when working with plastic injection molds. Plastics are highly malleable when melted and can be manipulated to fit into the complex patterns in a mold.  
  • Highly durable final products: Plastic injection molding machines work by transforming melted plastic into desired final products. The beauty of working with plastics is that they produce highly durable final products. With the incorporation of polymers, you can have products with high tensile strength. With plastics, you can target a broad range of customers and market segments. From construction to home and office, plastics have an almost ubiquitous presence in our society today. A diversified product portfolio can you gain a competitive advantage in the market.
  • High speed: Speed usually comes in handy when you are operating an industrial-scale molding operation. Plastic injection molding machines come with numerous cavities that allow you to produce numerous final products at any given time. The molding process is faster, especially with the right cooling system. Speed is also enhanced by the shorter molding cycle of plastics, particularly their cooling duration.
  • Product uniformity: These machines also come with product uniformity that makes them ideal for mass production processes. The last thing you need during a high-volume production project is final products with dissimilar features. Plastic injection molding uses repeat processes leading to the creation of identical products. The resulting brand consistency, even in cases of mass production, makes plastic injection molding machines very reliable when it comes to creating brand consistency and image.
  • Low production cost: Plastics are easy to purchase and melt. The molding cycle is also relatively shorter, which translates in less production time. Overall, you’ll spend on the production process leading to a reduction in your costs and an increase in your bottom lines.

Take-Home

Plastic injection molding machines come with operational flexibility that makes them ideal for large scale production. The machines also use a repeatable process that produces uniform final products. If you in the market for a cost-effective and highly efficient molding machine, consider going for one that uses plastic injection technology.

7 Practical Tips for Successful PP Injection Molding

by Chirag March 5, 2020
written by Chirag

Polypropylene (PP) is increasingly popular in the world of injection molding. Thanks to its chemical resistant design and low-density consistency, it’s frequently used in industries such as the automotive and the medical. 

Injection molding with PP resin brings a ton of benefits but also has its challenges throughout the molding process. Here is a selection of seven practical tips for excellent PP injection molding. 

5. Injection Molding (2)

1.   Be Patient with the injection process

It is expected for the injection process to consume most of the cycle. This is important because injection has a crucial role in the control of shrinkage. The more accurate the injection, the better the output. So, let it take its time and don’t make anything that might rush the injection process. 

2.   Injection pressure needs to be between 800 psi and 1500 psi

This is another variable that can influence potential issues with PP injection molding. As a general rule, the injection pressure needs to reflect the size and construction of the item. In most cases, the pressure needs to be capable of filling around 99% of the part to stop problems with sticking and flashing.

3.   Set the mold temperature to range from 50°-150° F

This is important because it reduces surface imperfections and stress on the item. Furthermore, it is also essential for the mold to be cooled uniformly. That way, the item can be easily ejected from the mold. 

4.   Set back pressure to be between 50 and 100 psi

That’s the ideal range for pp injection backpressure, which leads to improved cycle time. The only exception is if there is pigment mixing. In that case, the backpressure can be set somewhat higher.

5.   Don’t rush the hold time

This is a common mistake that should be avoided at any cost. Simply resist the urge to take part in the mold before it has been completely cooled. Failing to do so can potentially lead to shrinkage and warpage. Make sure that the part is cooled to around 130° F before you remove it from the mold.

6.   Don’t let minor sticking stand on your way

Truth is sticking is not that common with PP injection molding. That’s because PP has excellent release properties. But, if some minor sticking still happens, it can be corrected by either using a PP grade that has been already lubricated internally or by making adjustments to the mold. In both cases, the changes are easy and fast.

7.   Work with a trained professional

Polypropylene resin injection molding is great and can help you make excellent products with top quality. However, if you lack the experience, the knowledge, or both, you can find yourself in a world of troubles. 

If you don’t want this to happen to you, make sure that you have the support of a trained industry professional. He/she should have been in this industry for many years that has a ton of experience and can guide you throughout the entire process.
