摘要： A ripple detecting device for detecting a ripple from an armature current outputted from a motor by overlapping a low band noise having a frequency of one/n (wherein “n” is a natural number more than 1) includes an initial ripple detecting device for detecting a cycle of the ripple in advance, a feature detecting device for detecting a feature of the ripple from the armature current outputted from the motor.
