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 rotate ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

Encoder specialist POSITAL has expanded its line of kit-style encoders for feedback for servo and stepper motors with new models that utilize the same mounting form factor as incremental kit encoders ...

They do this with greater efficiency and less motor heating because motor phase currents are regulated up and down according to need. Performance of the closed-loop steppers are similar to servo ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...
