3-Axis Parallel Robot with AlphaStep Absolute Stepper Motors

Posted by Johann Tang on Oct 29, 2020 8:25:46 PM

Remember the days when we used to go to in-person events, such as trade shows?  Robot demos have always generated a lot of foot traffic in booths.  What's better to illustrate the synchronism of closed-loop stepper motors than 3 motors working together to create one specific motion?

What Determines Motor Life?

Posted by Johann Tang on Sep 30, 2020 10:30:00 AM

Knowing how to use a product properly can make a huge difference in its performance and life.  For example, knowing how to maintain cast iron pans properly can make them last longer.  With electric motors, understanding the factors that affect motor life is the first step to extending life and decreasing costs in the long run.

Wiring Basics: Unipolar vs Bipolar

Posted by Johann Tang on Aug 28, 2020 9:03:36 PM

An easy way to alter the speed and torque characteristics of a stepper motor is to connect it to a different type of driver or change its wiring configuration.  However, there's more to it.  Knowing the pros and cons between "unipolar" and "bipolar" can make or break your stepper motor performance.

The Differences Between Brushed and Brushless DC Motors

Posted by Johann Tang on Jul 31, 2020 7:32:03 PM

I will never forget my first engineering project involving motors.  I built a small elevator for a science class back in elementary school.  Of course, it worked great during the testing phase, but it failed to perform when it counted.

Minimizing the Effect of Load Fluctuations for Mixers

Posted by Johann Tang on Jun 30, 2020 12:00:00 PM

The viscosity change in liquids can vary the torque required for mixing.  For AC asynchronous motors such as AC induction motors, the rated speed is affected by load torque fluctuations, which may cause inconsistency in the final product.  Is there a better motor for the job?
