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

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?

Control Basics: The Difference Between Sink and Source Logic

Posted by Johann Tang on Apr 30, 2020 9:16:14 PM

For someone who has never had experience wiring I/O for motion control, it can be scary the first time.  If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage.  I still get that nervous feeling before I press the START button on a demo.  Murphy's Law, anyone?

Gear Basics: Backlash vs Lost Motion

Posted by Johann Tang on Apr 29, 2020 9:13:21 PM

The significance of position control accuracy of motors varies depending on the application.  For an AGV in a farm with DC motor-driven wheels, position control accuracy is probably not as crucial as a surgical robot where incisions are controlled by servo motors or stepper motors.

The Proper Way to Use a Gripper

Posted by Johann Tang on Mar 5, 2020 5:11:16 PM

A gripper is typically an end effector that is installed at the end of a robotic arm or on a cartesian robot and can be used to grip parts in order to transfer them from one location to another.  However, there's more to it than just closing the jaws to pinch a part.  In this post, we will explain how to properly grip a load while preventing damage.
