<P>PROBLEM TO BE SOLVED: To provide a motor controller for accurately and always correcting a torque instruction by simply calculating a change in torque constant, and correcting the torque constant if actual torque (i.e the torque constant) is changed relative to the torque instruction by a change in motor temperature (i.e. a temperature rise in a winding), and its torque constant correcting method. <P>SOLUTION: The motor controller is provided with means 15, 16 and 17 for correcting the torque constant based on acceleration and the torque instruction when the acceleration is fixed in the motor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
