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.

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.

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.

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.

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.

Stepper motors vibrate.  It's what they do.

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 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 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.

Along with the advancement of industrial technology, the method of maintaining motion control components of a machine, such as motors, drives, and sensors, has also evolved.  The most common method of maintaining a machine after a failure has occurred was the traditional method.  Realizing the need for improvement, maintenance personnel started to estimate life and replace motion control components before they fail.  More recently, with the advancement of IIoT (Industrial Internet of Things) and real-time availability of status data, another method was born.  While the two newer methods have the same goal in eliminating machine downtime, only one does it efficiently.
