Title:
PERMANENT MAGNET TYPE SYNCHRONOUS MOTOR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2014239583
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a permanent magnet type synchronous motor control apparatus capable of directly detecting power supplied to a motor while using a power detector and performing control so as to maximize output torque of the motor using the value.SOLUTION: A permanent magnet type synchronous motor control apparatus 100 comprises: a torque/current converting part 10 for converting a torque command into a command current; a current control part 15 for calculating a control current on the basis of the command current; a current/voltage converting part 25 for converting the control current from the current control part 15 into a command voltage; a three-phase inverter 35 for outputting power corresponding to the command voltage to a motor 50; and a rotational position detector 55 for detecting a rotational position of a rotor of the motor 50. At an output side of the three-phase inverter 35, a power detector is provided for measuring output power to the motor 50, and a current advance control device 75 is provided for controlling a current advance so as to maximize output torque of the motor 50 on the basis of the measured output power.
