10 Advantages of Geared Motors

Posted by Johann Tang on May 29, 2020 9:37:39 PM

Oriental Motor offers many pre-assembled geared motors for quality, consistency, and reliability.   In addition, gearheads from our industry partners increase the torque range of our motors further to accommodate more applications.  Here are some advantages of geared motors.

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.

Motor Sizing Basics Part 3: How to Calculate Speed, 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 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.

Motor Sizing Basics Part 2: How to Calculate 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: How to Calculate 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 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.

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.
