Opening-closing-body drive motor and opening-closing-body drive system

An opening-closing body driving motor comprising:

• a motor body for automatically opening and closing an opening-closing body of a vehicle;
• a drive circuit that supplies driving power to the motor body;
• and
• a control circuit including a PWM controller, the control circuit being 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, wherein
• 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,
• the information about the opening-closing state of the opening-closing body is information about a low-speed operation of the opening-closing body, and
• the PWM controller is configured to perform a sound producing operation by having the control frequency of the PWM control include a frequency in the audible range so that the motor body vibrates in the audible range in a section where a switching element of the drive circuit is turned on and off to operate the opening-closing body at a low speed rather than being kept on to operate the opening-closing body at a normal speed.
