Stepping Motors Fundamentals - Microchip Technology
AN907. Stepping Motors Fundamentals Author: Reston Condit TYPES OF Stepping Motors . Microchip Technology Inc. There are three basic types of Stepping Motors : Dr. Douglas W. Jones permanent magnet, variable reluctance and hybrid. University of Iowa This application note covers all three types. Permanent magnet Motors have a magnetized rotor, while variable reluctance Motors have toothed soft-iron rotors. Hybrid INTRODUCTION Stepping Motors combine aspects of both permanent Stepping Motors fill a unique niche in the motor control magnet and variable reluctance Technology . world. These Motors are commonly used in measure- The stator, or stationary part of the Stepping motor ment and control applications. Sample applications holds multiple windings. The arrangement of these include ink jet printers, CNC machines and volumetric windings is the primary factor that distinguishes pumps.
