Problems solved by technology

However, the magnetic field of the axial magnetic permanent magnet motor is basically constant, and it is generally a surface structure. The reactance of the alternating and direct axes is basically equal. When the motor is running at high speed, it is difficult to control the field weakening
When the motor is running as a motor, the range of constant power speed regulation is small, and when it is running as a generator, it is difficult to generate electricity at constant voltage with the change of the motor speed
The disadvantage of the non-adjustable magnetic field of the axial magnetic field permanent magnet motor has become a bottleneck for the further development of the motor

Embodiment Construction

[0021] The specific implementation of the double-fed hybrid excitation axial field permanent magnet motor will be further described in detail in conjunction with the accompanying drawings:

[0022] 1. The stainless steel frame 11 of the rotor is dug with a plurality of trapezoidal holes to form inner and outer circles of holes. The inner circle holes are staggered to insert permanent magnets 12 with opposite polarities, and the outer circle holes are embedded with iron core poles 13. The iron core poles 13 and The number of permanent magnet poles 12 is equal to the number of motor poles, and the stainless steel between the inner and outer circles of holes is a magnetic isolation area 15 to reduce the magnetic flux leakage between the permanent magnet 12 and the iron core pole 13, specifically as figure 2 shown.

[0023] 2. The left and right stators 3 and 7 have an auxiliary slot 14 at the position corresponding to the magnetic isolation area 15 of the rotor. The radial width...

Abstract

This invention relates to double mixture excitation axis field motor, which comprises One retardant left and right rotors on both sides, wherein, the rotor magnetic electrode is divided into inner and outer rings by isolation area with outer ring as iron electrode, inner ring as electrode alternating permanent part; two rotor iron core outside gear is fixed with magnetic field control coil fixed by motor main coil set. This invention adjusts the motor gas gap size by alternating magnetic control coil set to alternate inductance potensation size.

Description

technical field [0001] The invention relates to a permanent magnet motor, in particular to a double-feed mixed excitation axial magnetic field permanent magnet motor. Background technique [0002] After entering the 1990s, the axial field permanent magnet motor has attracted people's attention and interest due to its advantages of high efficiency, high density and low thermal load, and has been applied to automobile generators and wheel motors for electric vehicles, etc. field. However, the magnetic field of the axial magnetic permanent magnet motor is basically constant, and it is generally a surface structure. The reactance of the alternating and direct axes is basically equal. When the motor is running at high speed, it is difficult to control the field weakening. The range of constant power speed regulation is small when the motor is operated as a motor, and it is difficult to generate electricity at a constant voltage as the motor speed changes when the motor is operat...
