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.

Proud Moments To Be Thankful For

Posted by Johann Tang on Nov 27, 2019 8:05:07 PM

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.

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

Show & Tell: AC Reversible Motors and AC Electromagnetic Brake Motors

Posted by Johann Tang on Nov 21, 2019 8:38:57 PM

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.

Incremental vs Absolute Systems

Posted by Johann Tang on Sep 12, 2019 3:57:57 PM

The terms "absolute" and "incremental" comes up frequently in the world of position control.  The exact meaning changes according to the context they are used in.  For example, absolute and incremental motion can refer to the type of motion done by the motor either by relating it to the absolute home position or the last known position.  Absolute and incremental feedback can also refer to the type of feedback device being used with the motor.  In this blog post, we will focus on the feedback system and hopefully clarify some differences for you.

The Power of the AlphaStep Family

Posted by Johann Tang on Aug 28, 2019 2:37:43 PM

AlphaStep Logo

The word, "AlphaStep", describes Oriental Motor's patented Hybrid Control technology, which offers improved stepper motor performance by sensing the rotor position and automatically switching between open-loop and closed-loop operation when necessary.  First introduced in 1998 as the AS Series, the Alphastep Hybrid Control technology ushered in a new age where stepper motors can emulate servo performance at a lower cost.  Over the years, we improved the AlphaStep Hybrid Control technology with 2 major advancements to close the gap between stepper motors and servo motors even further.

This post explains the unique technologies offered within the AlphaStep family of products then summarizes the numerous integrated options available.  It also serves as a website navigation guide.
