A New High-Efficiency Stepper Motor Driver for Old Technology Stepper Motors
Authors: N. Greenough and C.C. Kung
Abstract:
Stepper motors have been used to drive
mechanical systems for many decades. Stepper motors require
a current-limited multiphase driver, and techniques have
evolved from simple resistive drivers to complex high
efficiency, high-performance switching devices. The first highefficiency
switching designs were patented over 30 years ago
and have become widely used throughout industry. This has
caused a shift in driver technology from a quad-drive system to
an H-bridge system, and a change in motor design from four
windings to two.
