PURPOSE:To provide a controller for a motor which can always control a stable motor speed by preventing a reset windup generated in a control system irrespective of a motor using speed to be a target and an input value of a motor using acceleration. CONSTITUTION:A first comparator 71 inputting part of a torque command signal 21 to be supplied to a power source 9 to compare it with a torque set threshold value 71a to generate and output an ON/OFF signal 22 responsive to the comparison result, and a second comparator for comparing a signal level of a rotary speed detection signal 20 from a towing truck 10 with a speed set threshold value 73a to generate and output an ON/OFF signal 24 responsive to the comparison result are provided in an integrated controller 8. A logical switch 74 for generating an integration ON/OFF command signal 25 for controlling an operation of an integrator 6 is generated based on a logical product of the signals 21, 24 output from the first and second comparators 71, 73 to feed back it to be supplied to the integrator 6 is provided. |
