<P>PROBLEM TO BE SOLVED: To provide a motor controller equipped with an inertial moment identifier which can identify the load inertial moment of a motor coupled with a load having a limited movable range only through minute operation with low rigidity. <P>SOLUTION: The motor controller comprises an inertial moment identifier 107 having a torque command Fourier converter 108 outputting torque command Fourier coefficients by receiving a torque command, a motor position amplitude operating unit 109 outputting a motor position amplitude by receiving a motor position, and an inertial moment operation unit 110 for calculating an inertial moment identification value by receiving the torque command Fourier coefficients and the motor position amplitude. <P>COPYRIGHT: (C)2007,JPO&INPIT |
