dc step motor
- Posted: January 27, 2014
Q. How hot can we run a step motor without damaging it?
A. The temperature range of our motors is -20 degrees C to +150 degrees C.
Q. Can I get a step resolution smaller than 1.8″?
A. All of our motors are a standard 1.8″ in full-stepping. You can change the size of the step by purchasing drives that either have half-stepping or microstepping capabilities.
Q. How does a step motor work?
A. A step motor has two primary pieces, the rotor and stator. The stator is made out of coils of wire called the windings and the housing. The rotor is a magnet with teeth which rotates on bearings inside the stator. When current is passed through the stator windings, it produces a magnetic force that holds the rotor in a locked position, the amount of torque needed to exceed this force is called the holding torque. As current is switched in the windings, the motor takes “steps” or small movements in one direction. This movement is...Categories: Technical Support
