Title (EN) METHOD FOR MACHINING PERMANENT MAGNETIC DIRECT-CURRENT BRUSHLESS MOTOR
(FR) PROCÉDÉ D'USINAGE D'UN MOTEUR SANS BALAI À COURANT CONTINU MAGNÉTIQUE PERMANENT
(ZH) 一种永磁直流无刷电机的加工方法
Abstract:
(EN) Provided is a method for machining a permanent magnetic direct-current brushless motor, the method comprising the following steps: machining a semicircular acceleration notch (3) having a magnetic flux control function at the middle position of a groove tooth between two adjacent stator grooves (5); forming semicircular isolation between the two adjacent stator grooves by means of the acceleration notch having a magnetic flux control function; and forming a local eddy magnetic field in the acceleration notch having a magnetic flux control function. By means of the machining method, the magnetic flux and rotation speed can be precisely controlled, and the control difficulty is lowered. Moreover, the accuracy of Hall signal acquisition is improved, the reliability of Hall signals is guaranteed, and the motor consistency is improved.
(FR) La présente invention concerne un procédé d'usinage d'un moteur sans balai à courant continu magnétique permanent, le procédé comprenant les étapes suivantes consistant : à usiner une encoche d'accélération semi-circulaire (3) ayant une fonction de commande de flux magnétique au niveau de la position centrale d'une dent de rainure entre deux rainures de stator adjacentes (5) ; à former une isolation semi-circulaire entre les deux rainures de stator adjacentes au moyen de l'encoche d'accélération ayant une fonction de commande de flux magnétique ; et à former un champ magnétique de Foucault local dans l'encoche d'accélération ayant une fonction de commande de flux magnétique. Au moyen du procédé d'usinage, le flux magnétique et la vitesse de rotation peuvent être commandés avec précision, et la difficulté de commande est réduite. De plus, la précision de l'acquisition de signaux de Hall est améliorée, la fiabilité de signaux de Hall est garantie, et la consistance du moteur est améliorée.
(ZH) 一种永磁直流无刷电机的加工方法,步骤为:在相邻的两个定子槽(5)之间的槽齿中间位置上加工出半圆形的带磁通控制加速槽口(3),通过带磁通控制加速槽口在相邻两定子槽之间形成半圆形隔断,在带磁通控制加速槽口内形成局部涡流磁场。能够实现对磁通量及转速精确控制,降低控制难度,同时提高霍尔信号采集精准度,保证霍尔信号可靠性,提高电机一致性。
