<P>PROBLEM TO BE SOLVED: To provide a motor temperature monitor and control system that prevents a motor from overheating, and does not depend on the direct measurement of temperature in the motor, and to provide a method of monitoring and controlling the temperature in the motor. <P>SOLUTION: The method for limiting the dissipation of power in the motor to limit the temperature of the motor to the prescribed maximum value includes: a step for detecting ambient temperature near the motor 206, a step for determining the dissipation 316 of power in the motor, a step for estimating the temperature of motor wiring based on the detected ambient temperature and the determined dissipation of power in the motor, a step for determining the maximum dissipation of power in the motor to raise the temperature of the motor to the prescribed maximum value within a prescribed time period, and a step for limiting the dissipation of power in the motor to the determined maximum dissipation of power in the motor or smaller. <P>COPYRIGHT: (C)2007,JPO&INPIT |
