Abstract: A motor control device includes: a plurality of sensors detecting a rotation position of a rotor and outputting a position detection signal; a rotational speed determination part determining whether a rotational speed of a brushless motor is equal to or less than a predetermined threshold value based on the position detection signal; and a motor control part. An energization control part included in the motor control part uses, between a first mode and a second mode, different sensor signals serving as a trigger for an energization timing of each phase. In the first mode, an energization timing to a second phase is advanced relative to a timing at which the position detection signal of a first sensor turns on. In the second mode, an energization timing to the second phase is retarded relative to a timing at which the position detection signal of the first sensor turns on.

Abstract: A motor device is provided. A grommet member (80) is equipped with a pair of motor-side lip seals (82a1, 82a2) which elastically deform in the insertion direction of an external connector (CN) into a connector member (60), and are adhered to a connector cover part (71) (contact surface 70a) of the cover member (70); hence, it is possible to configure in a manner such that the mounting direction of the grommet member (80) onto a gear case (31), and the adhesion direction of the pair of motor-side lip seals (82a1, 82a2) to the cover member (70), or in other words, the direction in which sealing properties increase, are the same direction.

Abstract: A fan shroud and a blower device are provided. The fan shroud includes a shroud wall surface and a plurality of ventilation openings. The shroud wall surface extends around a fan along a radial direction orthogonal to a rotation axis. The plurality of ventilation openings are formed through the shroud wall surface in a thickness direction of the shroud wall surface to allow passing of wind generated by a fan motor. A width of a wall surface side opening on a downstream side of the wind in the ventilation opening is smaller than a width of a lateral wall side opening on an upstream side of the wind in the ventilation opening.
