A controller is operable in one of a plurality of operational modes, which include an estimated temperature computation performing mode for performing computing of an estimated temperature of the motor and an estimated temperature computation non-performing mode for stopping the computing of the estimated temperature of the motor. An operational mode of the controller is changed from the estimated temperature computation performing mode to the estimated temperature computation non-performing mode according to a predetermined condition in a stopped state of the motor.

Motor control system

A position detecting device of a moving body can detect the position of a window glass of a power window device with high precision, and can set an initial position of the window glass without making any complicated adjustment. Further, this device can be realized with a simple structure and at low cost. Furthermore, the position detecting device and the vehicle door can reliably maintain an original assembly function in a normal assembly state into the moving body. The position detecting device 30 has a pushing button 202. Rotation of a ring gear 46 can be compulsorily prevented by pushing the pushing button 202 even in an operating state of a motor. Thus, if the motor is driven by pushing the pushing button 202, the position detecting device can be reliably assembled into a vehicle body in the normal assembly state irrespective of a rotating position of a motor rotating shaft (e.g., a moving position of the window glass) so that an original function of the position detecting device can be reliably maintained.
