The principles of AC motors are considered specifically from the variable frequency point of view, and this chapter concentrates on the effects of harmonics. The different types of power Reviews: 1. AC motors. Power switching devices. The six-step voltage source inverter for induction motors. The pulse width modulated voltage source inverter for induction motors. The six-step current source inverter drive. The six-step synchro-convertor system for synchronous motors. The current source inverter for the capacitor self-excited induction motor.   Description This book is intended to explain the technical principles involved in the many AC variable speed drive systems available today. It deals with all the DC link inverter and direct AC to AC converter systems that are in commercial use.4/5(1). 6 The six-step current source inverter drive + Show details-Hide details p. – (37) This chapter discusses the design of six-step current source inverter drives. In this system, the inverter switches operate to alter the path the current takes through the circuit and the motor, directing it to those motor windings which will cause the appropriate level and direction of Cited by:

Variable Frequency Ac Motor Drive Systems. Written in straightforward "user" language, this fully revised and updated edition provides an authoritative, yet practical guide for the engineer or technician involved in specifying, applying, maintaining or operating variable frequency drives (VFDs).4/5(2). LAPOND High Performance VFD Inverter VFD Drive KW V 3HP A,Variable Frequency Drive for Motor Speed Control,SVD-PS Series. Excellent value for the money. I'm using one of these to drive a 3 hp 3 phase air compressor I picked up for my home shop. I deal with a lot of VFD's in my profession. Automation Direct is the cheapest. Alternating Current Induction Motor Design Introduction Electric motor systems consume 20% of all energy generated in the United States, 57% of all electrical energy, and 70% of electrical energy consumed by industry. Over billion motors, of all types, are presently in use in the United States at this time.

Features – Controlling variables are voltage and frequency – Simulation of variable AC sine wave using modulator – Flux provided with constant V/f ratio – Open-loop drive – Load dictates torque level Unlike a DC drive, the AC drive frequency control technique uses parameters generated outside of the motor as controlling variables, namely voltage and frequency. Summary: This book is intended to explain the technical principles involved in the many AC variable speed drive systems available today. It deals with all the DC link inverter and direct AC to AC converter systems that are in commercial use. The basics: Variable frequency drives adjust your motor speed to closely match your output requirements, typically resulting in energy savings of 10 to 50%. We offer drives from 1/8 to 1,+ horsepower in all types of enclosures, for almost any application. Our systems integration division can build custom drive panels as well.
