Abstract: A motor driving device includes a control unit which outputs a pre-driving signal to control a motor based on command information of an input target number of rotations and detection information of a number of rotations of the motor, and a motor driving unit which drives the motor based on the pre-driving signal. The control unit includes a speed control circuit which outputs speed command information based on the command information of the target number of rotations and the detection information, a stop control circuit which when an input of the command information of the target number of rotations is stopped, outputs stop command information after a predetermined time elapses from detection of stop of the motor, and a driving signal generation circuit which generates a control signal based on the stop command information and the speed command information.

Abstract: There is provided a motor driving control device including a state determining unit which determines whether a motor can perform a slow start operation based on a rotating state and a driving state of the motor, a control unit which generates command information corresponding to a speed at which the motor is to be rotated, based on a determination result of the state determining unit, and a motor driving unit which outputs a driving signal corresponding to the command information generated by the control unit to the motor so as to drive the motor. When it is determined that the motor can perform the slow start operation, the control unit generates the command information such that the motor performs the slow start operation.
