The encoder is attached to the motor shaft and delivers signals that will indicate speed or position. Rotary encoders come in two basic flavors: incremental and absolute.

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rot… ...

A rotary encoder is an electro-mechanical device for converting the angular position of a shaft or axle to a digital code. For many applications and equipment that need to track object location, ...

Motion control is hardly a small matter to get to grips with in today’s ever-more automated age. Indeed, it has been ...

– Make your stepper motor applications extremely compact ! – Make sure that you never miss a step again, thanks to the on-board encoder and control algorithm !

By counting pulses from the optical sensors, he’s able to precisely position the tube in the jig for cutting and drilling operations. See it in action in the video after the break.

Oriental Motor of Japan is offering stepper motors with battery-free multi-turn absolute position encoding that can ride through power-loss. The encoder, dubbed ‘mechanical absolute encoder’, combines ...
