A motor control system includes a drive unit, a backup control unit, and a power unit. The drive unit is electrically connected to the power unit, and is configured to convert a received low-voltage drive signal into a high-voltage drive signal and output the high-voltage drive signal to the power unit. The power unit outputs, according to the high-voltage drive signal, a power supply drive signal provided by a high-voltage battery. The power supply drive signal is configured to drive a motor connected to the power unit to rotate. The backup control unit is electrically connected to the drive unit. The drive unit is configured to output a diagnosis signal indicating a running status of the drive unit to the backup control unit.

A ventilating apparatus includes a panel, a motor, a circuit assembly, and the apparatus stops an operation of the motor and notify a user when the panel is opened independently of a specific driving condition. The circuit assembly includes a switch which is closed when the panel is coupled to a body, and opened when at least a part of the panel is separated from the body, a motor of which an operation is stopped when the switch is opened, and a microcomputer which is connected to the switch and outputs a notification signal in response to the opening of the switch..

Disclosed is a safety system for a stairlift. The Safety system comprises a component for sending and receiving an electromagnetic signal that includes a light emitting device such as an LED and a light receiving device such as a photo resistor, an electromagnetic signal interrupter like a movable vane, a moveable activator, and a processor. The activator is configured to be moved by a user of the stairlift, which in turn causes the signal interrupter to interrupt a first electromagnetic signal.

A motor controller that is configured to switch power supply phases of the motor, to perform a limit-position abutment control by rotating the motor to a movable limit of a movable range of the rotation object to learn a reference position of the motor, perform a power-saving return control afterwards, in which a power supply to the motor is stopped, thereby returning a rotation position of the motor toward a target rotation position, and stop the rotation of the motor by simultaneously supplying power to a preset phase of the motor, when the rotation position of the motor reaches the target rotation position. In such manner, the power consumption as well as the heat generation of the motor are reduced for returning the rotation position of the motor to a preset rotation position after the abutment control of the motor.

A power optimizer system for power closure panels includes a closure panel power actuator system comprising at least a motor operatively connected to a lift-assist member and a closure panel counterbalancing member. A controller is configured at least to determine an optimal electrical current draw for the power actuator system according to one or more inputs relating at least to a vehicle ambient temperature and grade.

An electronic device includes a signal trigger circuit, a flat-motor drive circuit, and a flat motor. The signal trigger circuit sends a starting instruction to the flat-motor drive circuit for instructing to start the flat motor. A processor of the flat-motor drive circuit sends a first triggering instruction to a voltage processing circuit of the flat-motor drive circuit after receiving the starting instruction. The voltage processing circuit provides a first working voltage V1 to the flat motor after receiving the first triggering instruction, and provides a second working voltage V0 to the flat motor after a first time period. V0<V1≤V2, V0 is a rated voltage value of the flat motor, and V2 is a maximum forward voltage value that the flat motor can bear when the flat motor is started.
