Embodiment Construction

[0031] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] figure 1 It is a longitudinal sectional view of the hybrid excitation starter generator of the present invention. The shown hybrid excitation starter generator consists of shaft (1), bearing (2), motor end cover (3), field winding (4), first rotor core (5), first armature winding (6), casing ( 7), stator core (8), permanent magnet (9), second armature winding (10), second rotor core (11), belt pulley (12). The first rotor core (5), the second rotor core (11) and the stator core (8) are all disk-shaped and coaxial with the shaft (1), and the stator core (8) is located axially on the first rotor core Between (5) and the second rotor core (11), the first rotor core (5) and the second rotor core (11) are fixed on the shaft (1).

[0033] The sides of the first rotor core (5) and the second rotor core (11) opposite to the stator core (8) have 4N fan-shaped annula...

Abstract

A hybrid excitation starter generator proposed by the present invention includes a shaft, an excitation winding, two rotor cores, two sets of armature windings, a stator core, a permanent magnet and a pulley, etc.; 4N fan-shaped raised rotor poles; the stator core has 6N fan-shaped raised stator poles on the side opposite to the two rotor cores, and each stator pole is wound with an armature winding; the stator core is embedded with There are field windings parallel to the axis, the field windings are wound around three stator poles and the winding directions of adjacent field windings are opposite; a permanent magnet is embedded in the root of the fan ring where the three stator poles wound by the same field winding are located, The permanent magnets are also parallel to the axis. The hybrid excitation starter generator of the present invention realizes the brushless motor, can effectively utilize the advantages of small axial size and compact structure of the disc motor, and also effectively utilize the advantages of the hybrid excitation motor for convenient adjustment of the air gap magnetic field.

Description

technical field [0001] The invention relates to a hybrid excitation starter generator, which belongs to the technical field of automobile electric appliances. Background technique [0002] In traditional automotive electrical appliances, starting and power generation are completed by two independent systems. Generally, there are large starting noise, low speed, incomplete combustion, serious emission pollution and low generator power, which cannot meet the increasing power consumption of automotive electrical appliances. Increased needs are not enough. With the rapid development of electronic and computer control technology, inspired by the integrated motor system of starter and power generation in aircraft, starter generators have begun to be used in automobiles. The starter generator can not only be used as a motor to start the engine, but also can be used as a generator to supply power to electrical equipment. With the development of automobile technology, starter gener...
