Can be prevented from exceeding the duty upper limit value of the basic sine wave. For this reason, sufficient motor characteristics can be obtained while suppressing magnetic vibration.
  • the inclined surface 33e is formed to be inclined and flat so as to gradually move away from the salient pole 35 as it goes from the radial outer end of the salient pole contact surface 33d toward the outer peripheral surface 33a of the permanent magnet 33.
  • inclined surfaces 33 e on both sides in the circumferential direction are parallel to a straight line L connecting the circumferential intermediate portion 33 c of the permanent magnet 33 and the axis C ⁇ b> 1 of the shaft 31. For this reason, the two inclined surfaces 33e are also parallel to each other.
  • the controller unit 4 that controls the drive of the motor unit 2 includes a controller board 62 on which the magnetic detection element 61 is mounted, and a cover 63 provided so as to close the opening 40a of the gear case 40.
  • the controller board 62 is disposed opposite to the sensor magnet side of the worm wheel 45 (opening 40a side of the gear case 40).
  • the connection method of the coil 24 is the Y connection method
  • the fifth harmonic is superimposed on the basic sine wave.
  • the fifth harmonic is in antiphase with the fundamental sine wave. Therefore, it is possible to prevent the upper limit value of the drive voltage from exceeding the duty upper limit value of the basic sine wave without reducing the output duty of the drive voltage on which the fifth harmonic is superimposed. Therefore, sufficient motor characteristics can be obtained while suppressing the magnetic vibration of the motor unit 2.

Abstract

L'invention concerne : un moteur à l'aide duquel il est possible d'obtenir des caractéristiques de moteur adéquates tout en supprimant une oscillation magnétique dans le cas où le rapport entre les nombres de dents et le nombre de pôles magnétiques des aimants permanents est de 2:3 ; un moteur d'essuie-glace sans balai ; et un procédé de commande du moteur. Ce moteur est pourvu : d'un stator ; d'une bobine qui est enroulée autour des dents du stator ; d'un noyau de rotor qui est fixé à un arbre tournant sur le côté radialement interne d'un noyau de stator du stator et qui a un centre de direction radiale qui coïncide avec l'axe de rotation de l'arbre ; d'une pluralité d'aimants permanents qui sont disposés sur une surface circonférentielle externe du noyau de rotor ; et des pôles saillants qui sont formés entre les aimants permanents dans la surface circonférentielle externe du noyau de rotor de manière à faire saillie radialement vers l'extérieur. Le rapport entre le nombre de dents et le nombre de pôles magnétiques des aimants permanents est de 2:3. La bobine a une structure à trois phases et a une connexion en Y. La forme d'onde de la tension de commande à appliquer à la bobine est obtenue par superposition d'une cinquième harmonique sur une onde sinusoïdale fondamentale. La cinquième harmonique est en opposition de phase avec la phase de l'onde sinusoïdale fondamentale.
