PROBLEM TO BE SOLVED: To provide a controller of a motor which can obtain a torque close to a required torque, even in a starting state or in a very low revolution operating state, while a sensor with a relatively low resolution is employed to suppress cost. SOLUTION: This motor controller controls a current supplied to a motor 1, by using a signal from a rotation position detection means 2 for detecting a rotation angle of the motor 1 for conrolling the motor 1. The controller has a position detection result changing means, which changes an output value from the rotation position detection means 2, according to a comparison result between the revolution of the motor 1 and a predetermined value of revolution speed, so as to reduce the maximum value of a decline of the torque of the motor 1. |
