Title: Controller for ac motor
Inventor: SHINDO TOMIO
IPC: B60L9/18
Filed: 1986-04-22
Abstract: PURPOSE:To contrive pulsation not to be generated on an AC motor and prevent oscillation from being applied to the side of a load or the like, by controlling the increment or reduction of motor torque when the rotation and stop of the AC motor are repeated. CONSTITUTION:When a vehicle in a specified load state is run at a slight and constant speed and when the rotation and stop of an induction motor c are repeated, then motor torque is increased as well as or more than load torque to be controlled, and so the induction motor c is continuously rotated and driven, and so the pulsation of an induction motor 10 is suppressed, and accordingly, the oscillation of the vehicle is extremely attenuated. As a result, without generated oscillation, the vehicle can be driven at a slight speed suitable for the operation of an accelerator.
