Abstract: An opening-closing body is operated toward an end position of the movable range, a section where the motor application voltage is set to a fixed value defines a first section. A section set between the first section and the end position defines a second section. The controller is configured to execute speed reduction control and stop control in the second section. At a point in time when the rotation speed of the motor body becomes less than or equal to a second threshold value, in the first section or the second section, the controller sets the motor application voltage that is applied from the point in time until the opening-closing body reaches the end position and the stop control is executed to a voltage value that is greater than or equal to the motor application voltage applied at the point in time.

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.
