Servomechanical Power-Electronic Motor Drives
S.Leeb A modern actively controlled motor drive is a system that combines a power-electronic circuit and a motor. The electronics in the drive system control the behavior of the mechanical shaft of the motor. For example, the electronics might be configured to provide the possibility of directly varying the shaft speed or torque based on a low-power, “signal level” command input. The earliest variable-speed drives avoided the need for (the unavailable) highly capable power electronic devices by cascading motors and generators, i.e., an M-G set. In an M-G set, a prime mover, such as a steam turbine or an induction motor runni…
