A motor includes: a stator having an annular stator core and multiple teeth protruding radially inwards from the stator core; a coil wound around the teeth; a shaft rotating around the rotation axis radially inside of the stator core; a rotor core fixed to the shaft; magnets positioned on the outer peripheral surface of the rotor core; a salient pole positioned between magnets adjacent to each other in the circumferential direction; an applying portion applying a voltage to the coil; and an applying control portion controlling the applying portion. The ratio of the number of magnetic poles of the magnets and the number of teeth is 2:3. The voltage is a rectangular wave, and its application is started when the tip of the salient pole does not face an opening in the teeth.

A device, and a corresponding method, for controlling a wiper of a vehicle may include: a storage that stores a reference table, wherein each wiper operation mode corresponding to each rainfall and each sensitivity level is recorded in the reference table; a rain sensor that measures the rainfall; a wiper switch that receives a wiper operation mode and a sensitivity level input from a driver; and a controller that detects a wiper manipulation pattern of the driver based on the measured rainfall and that changes the reference table to a driver-customized-table based on the wiper manipulation pattern of the driver.

A wiper system for a vehicle is provided. The wiper system includes a driving assembly. The wiper system further includes a supplementary wiper having a first end that is coupled to a first pivot point of the driving assembly. When the wiper system is activated, the driving assembly is configured to swing the supplementary wiper about the first pivot point from a resting position to an extended position. The supplementary wiper is configured to be statically disposed at the extended position to prevent water from passing over one of two A-pillars of the vehicle to a side window of the vehicle. When the wiper system is deactivated, the driving assembly is configured to stow the supplementary wiper back from the extended position to the resting position.

A motor control device for controlling a brushless motor including a rotor and a three-phase armature coil includes: a position detection unit which detects the rotational position of the rotor; a control unit which outputs, in a first control mode or a second control mode, a first drive signal or a second drive signal to an inverter at a current-supply timing based on the rotational position of the rotor; and the inverter which outputs a first current-supply signal or a second current-supply signal to the three-phase armature coil when the first drive signal or the second drive signal is input. For any two of the three phases, a duty value when the duty of the applied voltages is the same is larger in the second control mode than in the first control mode.
