Summary

Written with the maintenance technician in mind, Electronic Variable Speed Drives, 2nd Edition serves as a practical guide to understanding different types of drive circuits, including: brushless DC motor controllers, chopper circuits, variable voltage inverters, current source inverters, and flux vector drives. Emphasis throughout the book's fourteen chapters is on troubleshooting and maintenance, with entire chapters devoted to DC Drive troubleshooting and AC Drive troubleshooting. All explanations and theory are fundamental and presented in a clear, concise, no-nonsense manner, with very little use of formulas. This one-of-a-kind book also features a comprehensive glossary to aid in mastering terminology, as well as chapter-specific objectives and review questions designed to reinforce key points.
