Title:
MOTOR CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2013/108356
Kind Code:
A1
Abstract:
Provided are a torque-limit output unit for outputting a torque-limit value such that the power consumption of a motor is within a predetermined motor power limit value and the voltage amplitude required for driving the motor is within a predetermined voltage limit, a position command generating unit for generating a position command with respect to a target position in accordance with the torque-limit value, and a power/voltage-limiting unit for performing a process in which a motor torque current is corrected on the basis of an excess amount of motor power consumption relative to a motor-power-consumption limit value and a process in which a motor-excitation current is corrected on the basis of an excess amount of a motor torque component voltage relative to a motor torque component voltage limit value. It is thereby possible for power consumed by the motor and the voltage required for driving the motor to be kept within a predetermined range.
