Kind Code:
A1
Abstract:
A fan motor system (1) is provided with: a fan motor unit (10) comprising a motor (101) and a controller (100) which controls the rotational speed of the motor (101) in accordance with an input command value; a command value outputting portion (110) which, when the motor (101) in a stopped state is activated, outputs the command value to the controller (100) while increasing the command value from a prescribed initial value; a startup detecting portion (111) which detects the start of rotation of the motor (101) on the basis of the actual rotational speed of the motor (101); and a startup command value recording portion (112) which acquires and records a rotation startup command value, which is the command value output by the command value outputting portion (110) at a time corresponding to the time at which the start of rotation is detected. The command value outputting portion (110) determines the initial value with reference to the recorded rotation startup command value, when the motor (101) is activated.
