3 Things to Know About the BLV Series Update

Posted by Johann Tang on Mar 15, 2021 12:00:00 PM

The BLV Series is one of two DC-input brushless motor speed control systems we offer.  While a brushless motor with hall-effect sensor feedback provides constant torque, wide speed range, and speed regulation, the BLV driver offers unique functions designed for mobile robots, such as low battery operation and ramp operation.

Speed Control Basics: VFD or Triac for AC Induction Motors?

Posted by Johann Tang on Feb 26, 2021 9:09:03 PM

When a voltage is applied to an AC induction motor, it runs at a certain speed.  Variable speed requirements for AC induction motors are typically fulfilled by a 3-phase motor and an inverter or VFD.  This blog post also introduces another option.

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.

The Differences Between Brushed and Brushless DC Motors

Posted by Johann Tang on Jul 31, 2020 7:32:03 PM

I will never forget my first engineering project involving motors.  I built a small elevator for a science class back in elementary school.  Of course, it worked great during the testing phase, but it failed to perform when it counted.

Minimizing the Effect of Load Fluctuations for Mixers

Posted by Johann Tang on Jun 30, 2020 12:00:00 PM

The viscosity change in liquids can vary the torque required for mixing.  For AC asynchronous motors such as AC induction motors, the rated speed is affected by load torque fluctuations, which may cause inconsistency in the final product.  Is there a better motor for the job?

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?
