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
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
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]
