Abstract: Disclosed is a vehicular opening/closing body control device including: a positional information acquisition; a storage part; and a motor control part. The motor control part includes: a drive start part that operates the motor based on the positional information so that the opening/closing body in a stopped state is moved; and a drive part that performs feedback control of the motor based on the positional information and the target value so that the movement speed of the opening/closing body which has been started to move by the drive start part reaches the target value. The drive start part generates a first output in the motor when the opening/closing body is at a first position, and generates a second output smaller that the first output in the motor when the opening/closing body is at a second position closer to a fully closed position than the first position.

Abstract: 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.

Abstract: A blower device includes a motor having an output shaft and a housing; a fan rotationally driven by the motor; and a shroud having a shroud body with a fan installation hole, and a motor mounting part for mounting the motor arranged inside the fan installation hole when viewed in an axial direction of the output shaft. The motor mounting part includes an inner cylinder surrounding a periphery of the motor from a radial outer side of the output shaft; an outer cylinder surrounding the inner cylinder from the radial outer side; and spokes connecting the inner and the outer cylinders. The inner cylinder includes a top wall covering the motor from above while the shroud is fixed. A back end edge of the top wall, which is located on a positive pressure side when the fan is rotated, is located closer to the positive pressure side than the housing.
