摘要： The axial direction of a worm wheel is defined as a motor short-transverse direction, and a plane orthogonal to the motor short-transverse direction is defined as a motor flat plane. An imaginary plane contacting a first end of a sensor magnet in a motor short-transverse direction and parallel with the flat plane is defined as a first imaginary plane. An imaginary plane contacting a second end of the sensor magnet in the motor short-transverse direction and parallel with the flat plane is defined as a second imaginary plane. A control circuit board is provided with a rotation detecting element that detects rotation of the rotary shaft of the motor. The control circuit board is arranged to be parallel with or inclined relative to the flat plane, and is provided between the first and second imaginary planes.

摘要： 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.

摘要： An open-close body driving device includes a motor configured to open and close an open-close body included in a vehicle and a controller controlling a movement speed of the open-close body driven by the motor. The controller is configured to move the open-close body at a normal speed based on a vehicle-side operating signal output by operation of an operating switch installed on the vehicle and at a speed lower than the normal speed based on a remote operating signal output by operation of a mobile device. The controller is configured so that in a shutting region having a predetermined dimension from a fully-closed position toward an open side, closing movement of the open-close body based on the remote operating signal is slower than closing movement of the open-close body based on the vehicle-side operating signal.
