    摘要： Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.

    摘要： In a brushless wiper motor, first and second pressing claws (43a and 43b) are formed on an outer periphery (OP) of steel sheets (34a) forming a stator core (34), and press-fitted to an inner periphery (IP) of the motor housing unit (31) so that the stator core (34) is fixed to the motor housing unit (31), base end portions of the first and second pressing claws (43a and 43b) are respectively connected to first and second walls formed on the outer periphery (OP) of the steel sheets (34a), and tip end portions of the first and second pressing claws (43a and 43b) each serves as a free end, and are directed in a circumferential direction of the stator core (34).

    摘要： A magnet 34 for the rotating shaft (first magnet, second magnet) is installed on the extended portion of the rotating shaft 33b in the gear housing 41, and Hall ICs 65a to 65c for the rotating shaft (first sensor, second sensor) are formed on the control board 60 inside the gear housing 41 so as to face the magnet 34 for the rotating shaft. The Hall ICs 65a to 65c for the rotating shaft are adapted to detect the rotation position of the rotating shaft 33b relative to the stator 32, that is, the rotation position of the rotor 33 relative to the stator 32, and the Hall ICs 65a to 65c for the rotating shaft are adapted to detect the rotation number of the rotating shaft 33b.
