Decay Modes for Motor H-Bridge Drivers

Posted on26 Feb, 201728 Nov, 2019

Recently we had a few customers asking about driving our DC gear motors with H-bridges, and specifically, whether they would need additional fly-back diodes for each transistor in the bridge. As it happens – you don’t, and there are a few options that can be Continue reading

5 Methods of Circuit Protection for Gearmotors Part 1

Posted on3 Mar, 201413 Dec, 2019

Note: this is the first of two parts looking at limiting current for gearmotors, our next post will complete the article. Our gearmotors are frequently used to drive a variety of industrial mechanisms, such as linear actuators or pulleys. A common design consideration in such applications is circuit Continue reading

Discrete H-bridge Circuit For Enhanced Vibration Motor Control

Posted on24 Oct, 201113 Dec, 2019

This bulletin covers some more advanced circuitry that is useful if we need better control of the vibration motors we’re using. A prime application for this, is, of course, using a vibration motor to provide haptic feedback. When using vibration motors (or Eccentric Rotating Mass [ERM] Continue reading
