A stepper motor is a “digital” version of the electric motor. The rotor moves in discrete steps as commande rather than rotating continuously like a conventional motor. When stopped but energize a stepper (short for stepper motor ) holds its load steady with a holding torque.

Wide spread acceptance of the stepper motor. AC Input stepper motor drivers offer superior torque characteristics over a wide speed range, from low to high speeds, providing a large speed ratio.

Supports Closed Loop control without gain tuning or hunting problems when used with the AZ Series (absolute mechanical encoder) motor or the AR Series (built-in resolver) . Five geared type stepper motor solutions, encoder and brake options and various motor windings are offered. Oriental Motor offers a wide range of single-phase and three-phase VAC input stepper motor drivers. Our closed loop and absolute type stepper motor drivers offer advanced functionality and features for your position control application. A full-step waveform is a gross approximation of a sinusoi and is the reason why the motor exhibits so much vibration. Various drive techniques have been developed to better approximate a sinusoidal . Electrical Engineering.

That is kind of like AC.

STEPPER MOTOR CONVERSION TO THREE PHASE AC PERMANENT MAGNET GENERATOR 1. With features that include high torque, high bus voltage and microstepping performance, and versions that accept an encoder to the rear shaft provides unparalleled AC . A servo motor can supply roughly twice their rated torque for short periods, providing a well of capacity to draw from when needed. In addition, servo motors are quite, available in AC and DC drive, and do not vibrate . We can also make motors that work using AC (alternating current) instead of DC. Speed-torque curves highlight the difference between stepper and AC permanent magnet (PM) servo motors of equal volume (Figure A). Steppers typically generate higher continuous torque at lower speeds than servo motors.

However, servo motors produce intermittent peak torques in this same low-speed range and . A Typical Small DC Motor. AC Motors are generally used in high power single or multi-phase industrial applications were a constant rotational torque and speed is required to control large loads such as fans or pumps.

In this tutorial on electrical motors we will look only at simple light duty DC Motors and Stepper Motors. AC Stepper Motor , Bipolar Stepper, and Unipolar stepper connection diagrams from Hansen Corporation.
