Abstract
An opening-closing body driving motor includes a motor body, a drive circuit, and a control circuit. The motor body is provided to automatically open and close an opening-closing body of a vehicle. The drive circuit supplies driving power to the motor body. The control circuit includes a PWM controller. The control circuit is configured to adjust the driving power by PWM control and control an operation mode of the opening-closing body through the motor body such that the operation mode is changeable. The PWM controller is configured to have a control frequency of the PWM control include a frequency in an audible range based on a predetermined trigger so that the motor body vibrates in the audible range, thereby performing a sound producing operation. The predetermined trigger includes information about an opening-closing state of the opening-closing body or information about activation and deactivation of a child lock.
