Abstract

The invention discloses a high-reliability six-phase isolated permanent magnet motor for a start-stop system and belongs to the technical field of vehicle motors. The motor comprises stator iron cores, a rotor iron core, permanent magnets, six-phase armature windings, a stator fixing block, a shell and a shaft; The rotor iron core is formed by stacking and pressing silicon steel sheets; ten convex rotor poles are uniformly distributed on the circumference of the rotor iron core; the pole arc length of each rotor pole accounts for a half of the polar distance of each rotor pole; each stator iron core is formed by three E-shaped sub iron cores; and each E-shaped sub iron core is provided with three stator poles, wherein the pole arc mechanical angle of the middle stator pole is 18 degrees, and the pole arc mechanical angles of the stator poles on the two sides are 12 degrees. According to the technology, one centralized excitation winding can be utilized to excite two armature windings; the armature windings can be divided into six phases according to different phase positions, the isolation performance of each-phase winding is good, and the reliability is high; and in addition, the motor provided by the invention can run as a power generator and also run as an electric motor.

Description

technical field [0001] The invention relates to a six-phase isolated permanent magnet motor for a high-reliability start-stop system, belonging to the technical field of special motors. Background technique [0002] Energy conservation and environmental protection have become the theme of the times today, and the allure of the idling start-stop system is self-evident. The idle start-stop system is considered to be a key technology for future automobile energy saving and emission reduction. Its working principle is to replace the original starter motor with a motor with idle start-stop function, which can realize automatic start-stop when necessary. Therefore, the reliability of the motor used in the start-stop system has become a key technology for the reliability of the start-stop system. [0003] At present, there are not many invention patents related to the motor used in the start-stop system. At the same time, the related patents mainly focus on the cost control and no...
