Embodiment Construction

[0014] The following examples refer to Figure 1~5 .

[0015] The disc-type three-phase magnetism-concentrating transverse magnetic permanent magnet motor of the present invention includes E-type silicon steel 1, permanent magnet 2, permanent magnet panel 3, winding 4, E-type silicon steel auxiliary plate 5, winding auxiliary plate 6 and rotating shaft 7.

[0016] The shape of the motor is disc-shaped, and the radial dimension of the motor is larger than the axial dimension, which is similar to the shape of the hub of an automobile. The motor is composed of E-type silicon steel 1, permanent magnet 2, permanent magnet panel 3, winding 4, E-type silicon steel auxiliary plate 5, winding auxiliary plate 6, rotating shaft 7, bearing 8, end plate 9, and shell 21. The rotor disk composed of permanent magnets 2 and permanent magnet panels 3 is located in the middle of the stator structure on both sides, and is fixed on the rotating shaft 7 by clips 20; the shell 21 and the single-sid...

Abstract

The invention discloses a disc type three-phase magnetic gathering type transverse magnetic field permanent magnet motor which is used for solving the technical problem of low permanent magnet utilization rate of existing transverse magnetic field permanent magnet motors. The technical scheme includes that a combined bilateral stator structure is adopted, stators on two sides are staggered to form a mechanical angle of 360/2N, wherein the N refers to the number of motor poles, a stator on one side is provided with three phases which are distributed circumferentially, a stator of each phase consists of 'E'-shaped silicon steel and a winding, permanent magnets are circumferentially embedded in a disc-shaped permanent magnet panel and are distributed into three circles, polarities of two adjacent permanent magnets on the permanent magnet panel are opposite, and the permanent magnets, the permanent magnet panel and a motor shaft form a rotating portion of the permanent magnet motor. The permanent magnets and the 'E'-shaped silicon steel forms the disc type three-phase magnetic gathering type transverse magnetic field permanent magnet motor with different polarities and different power levels, so that utilization rate of the permanent magnets, magnetic flux density of air gaps and output torque are improved, and axial volume of the motor is reduced.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to a disk-type three-phase magnetism-concentrating transverse magnetic field permanent magnet motor. Background technique [0002] With the rapid development of electric vehicles, hub motors have also been vigorously developed. The most researched is the permanent magnet synchronous motor. This type of motor belongs to the traditional two-dimensional magnetic circuit motor. It can only be applied to electric vehicles with the corresponding deceleration mechanism; sometimes in order to achieve a certain low-speed operation, a weak magnetic speed regulation scheme is adopted, but this is at the expense of the output torque of the permanent magnet motor. The permanent magnet hub developed by Harbin Institute of Technology Motors fall into this category. Professor H. Weh of Germany proposed the design idea of ​​transverse magnetic field motor, which is characterized by low speed and high out...
