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.

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?

Motor Sizing Basics Part 4 - Radial Load and Axial Load

Posted by Johann Tang on Mar 31, 2020 7:58:57 PM

Besides load torque, acceleration torque, speed, and load inertia, overlooking certain sizing parameters during the motor sizing process can literally make or break your machine.

Motor Sizing Basics Part 3: Acceleration Torque (and RMS Torque)

Posted by Johann Tang on Feb 27, 2020 9:05:40 PM

Now that we understand the calculations behind load torque and load inertia, we're two steps closer to motor selection.  You might be wondering why I separated load torque and acceleration torque calculations.  That's because in order to calculate for acceleration torque, load inertia and speed must be calculated first.

Motor Sizing Basics Part 2: Load Inertia

Posted by Johann Tang on Jan 17, 2020 7:51:53 PM

Other than torque or speed, another factor should be considered when sizing motors.

Motor Sizing Basics Part 1: Load Torque

Posted by Johann Tang on Jan 14, 2020 8:14:54 PM

Proper sizing of a motor requires that 3 criteria must be met: torque, load inertia, and speed.  For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.

What Does a Capacitor Do?

Posted by Johann Tang on Dec 26, 2019 4:55:25 PM

For a permanent-split capacitor type AC motor (also known as capacitor start and run AC motors), a capacitor is required for proper operation.  Enjoy a cup of coffee as we explain why.
