Embodiment Construction

[0034] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] figure 1 It is a longitudinal sectional view of a permanent magnet generator with a heater of the present invention. As shown in the figure, a permanent magnet generator with a heater consists of a shaft (1), a heater casing (3), a heater fan (4), a generator casing (6), a first rotor core (7), a first An armature winding (8), a permanent magnet (9), a second armature winding (10), a stator core (11), a second rotor core (12) and a generator end cover (13). The end of the shaft (1) is fixed with a heater fan (4), and the middle of the shaft (1) is successively fixed with a disc-shaped first rotor core (7) and a second rotor core (11), and the first rotor core ( 7) In the middle of the second rotor core (12) is a fan-shaped stator core (11). The stator core (11) is fixed on the generator casing (6); under the action of the bearing, the shaft (1) can drive the...

Abstract

The invention discloses a permanent magnet generator with a heater, which is composed of a shaft, a heater fan, a generator shell, two rotor iron cores, a permanent magnet, two sets of armature windings and a stator iron core, wherein the tail end of the shaft is fixed with the heater fan; two disc-shaped rotor iron cores are sequentially fixed in the middle of the shaft; rotor poles convex along the axial direction are arranged in opposite directions of the two rotor iron cores; the middle of the two rotor iron cores is the stator iron core; two end surfaces, facing the rotor iron cores, of the stator iron core are provided with stator poles; each stator pole is provided with one armature winding; and the permanent magnet is embedded at the fan-shaped root of the stator iron core. According to the permanent magnet generator with a heater, reliable integration of the heater and the generator can be realized; as the disc-type motor structure is adopted, the stator-rotor contact area is large, and the specific power of the motor is high; the rotor has no excitation source and can rotate reliably and at a high speed; and the two stators can form a complementary six-phase winding, and voltage fluctuations are thus reduced.

Description

technical field [0001] The invention relates to a permanent magnet generator with a heater, belonging to the technical field of automobile electric appliances. Background technique [0002] Due to its mechanical and electromagnetic structure, the disc permanent magnet motor is suitable for occasions with special requirements on torque and mechanical structure. A lot has been done in the research and application of disk permanent magnet motors at home and abroad, and the research direction is mainly concentrated in the wind power generators of disk permanent magnet motors and the motors for electric vehicles. [0003] The basic form of a disc motor is composed of a disc-shaped stator and a disc rotor with an axial plane air gap in between. Since the stator is also used as the magnetic circuit of the rotating magnetic poles, a thrust bearing is needed to ensure that the rotor does not move axially. However, because the motor has a single air gap, axial magnetic pull is gener...
