Title: Controller for motor
Inventor: SHIMAZAKI MITSUYOSHI
IPC: H02P6/12
Filed: 2002-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a controller for motor in which temperature rise of an armature coil or a switching circuit can be suppressed. SOLUTION: Temperature-sensitive resistor elements Rtu-Rtw, coupled thermally with the three-phase armature coils Lu-Lw of a motor 1, are connected in parallel, and a voltage signal Vt obtained across the parallel circuit of the temperature-sensitive resistor elements is inputted to the CPU of a controller 13. Temperature rise suppression control is made to limit the output from the motor, when the voltage signal Vt, expressed in terms of the temperature exceeds a set level. Since different voltage/temperature conversion tables are employed, when the motor is locked and operated steadily, protective operation can be effected either when the temperature of the three-phase armature coils Lu-Lw is increased abnormally and similarly during steady operation and when only the temperature of armature coil of a specific phase increases, when the motor is locked.
