Induction Motor Drives
Published 2015 · Computer Science
At present, induction motor drives are the most mature technology among various commutatorless motor drives. There are two types of induction machines (IMs): the wound-rotor and squirrel-cage. This chapter discusses various induction motor drives, including their system configurations, IMs, power inverters, and control strategies. There are three main types of control strategies for induction motor drives: the variable-voltage variable-frequency (VVVF) control, field-oriented control (FOC), and direct torque control (DTC). The induction motors for electric propulsion is principally similar to that for industrial application. When the electric vehicles (EV) adopt the single-motor configuration, the induction motor is generally designed for high-speed operation while using a planetary gear to step down the motor speed so as to match with the wheel speed. The Ford Siemens EV motor was one of the most well-developed induction motors for EVs.
