Welcome to Oriental Motor's "Engineering Notes" Blog:

Now that we understand the calculations behind load torque and load inertia, we're a little 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. 

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

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.

An AC motor is not working like it's supposed to.  What do you do?  Before replacing the motor, here are three ways to start troubleshooting your AC motor with a circuit tester.

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.

In the spirit of Thanksgiving, I thought I'd change gears (pun intended) and write about what Oriental Motor is thankful for.  

First, we are thankful for our customers for being our customers and helping us grow to be a globally reputable motion control manufacturer. 

Second, we are thankful for the awards and recognition we've received over the years.  It's always good to know that we're doing a good job and these accolades definitely serve as motivation to become even better at what we do.

While we are grateful for these awards and recognition, our greatest satisfaction comes from applying our award-winning products to solve motion control challenges for our customers.

AC motors have the same operating theory, but by changing its design a little, you can modify its characteristics to suit certain applications better.  In the last post, I focused on AC induction motors for unidirectional applications.  In this post, I will explain what makes AC reversible motors and AC electromagnetic brake motors ideal for start/stop, reversing, or vertical applications, and demonstrate how to operate them.

AC motors are simple to control, rugged, and cost effective for general purpose applications.  These reasons are why they are the most popular type of electric motor across various industries.  In this post, we will briefly introduce induction motors and demonstrate how to operate these motors.

Do you know how to use this graph?

Stepper motors vibrate.  It's what they do.  To minimize motor vibration, first we need to understand where they come from.
