Height, there is energy index higher；And motor is when being operated in high speed invariable power area, should be able to weaken air-gap field sufficiently low, make
Motor has speed adjustable range wider.Conventional axial magnetic field permanent magnet synchronous motor is due to the intrinsic spy of the permanent-magnet materials such as neodymium iron boron
Property, air-gap field is held essentially constant in motor, limits its application that occasion is directly driven in wide range speed controls such as electric automobiles.Mesh
Preceding people are expanded forever using weak magnetism speed expansion technology one after another in order to keep magneto output-constant operation in velocity interval wider
Magneto power output at high speeds.Realizing the scheme of weak magnetic control to magneto in the prior art mainly has two
Kind, one is to adjust armature supply by controller, and the demagnetization magnetic potential produced using direct-axis current component in armature winding goes to offset
The excitation magnetic potential that a part of permanent magnet is produced, the purpose of main flux is weakened so as to reach；Two is using composite excitation scheme, that is, to exist
A direct-flow magnet exciting coil is further added by the basis of conventional permanent magnet motor, the magnetomotive force that this DC coil is produced more than base speed is made
The purpose for weakening magnetic flux is reached for demagnetization magnetic potential.Although such scheme can reach the purpose for weakening magnetic flux, however it is necessary that increasing
Controller or direct-flow magnet exciting coil, can cause the increase of copper loss, and then cause system in the reduction of high velocity efficiency, and may
Cause permanent magnet irreversible demagnetization.
Therefore, the adjustable study hotspot as machine field in recent years of air-gap field of magneto how is realized,
One kind realizes that air-gap field is adjusted by changing permanent magnet magnetization level, is referred to as variable flux permanent magnet electricity truly
Machine.Such motor uses remanent magnetism high, the permanent-magnet material of low-coercivity -- aluminium nickel cobalt, fixed using DC pulse winding current or three-phase
D-axis armature magnetomotive force that sub- winding current is produced controls its intensity of magnetization, and its level of magnetization to be remembered, so that
The flexible modulation in air gap permanent magnet magnetic field is realized, under the premise of motor other performance indications are not sacrificed, wide speed regulating range fortune is realized
OK.Because the adjustable magnetic of the motor is the magnetized state of directly change permanent magnet, offset rather than using additional magnetomotive force, therefore
Can be described as a kind of controllable magneto of magnetic flux truly.
Southeast China University's woods crane cloud etc. proposes a kind of axial magnetic field Magneticflux-switching type durface mounted permanent magnet memory electrical machine, the motor
Though can realize that motor gas-gap magnetic field is adjustable by applying different electric currents on monophasic pulses if winding, the motor use only strong
The relatively low Al-Ni-Co permanent magnet of stupid power, the maximum air gap magnetic flux of motor is extremely difficult to the level of Nd-Fe-B permanent-magnet motor, electricity
Machine energy index is not fully up to expectations；Or in order to obtain enough magnetic fluxs, it is necessary to use thicker permanent-magnet material, and increase magnetic and
Degaussing magnetic flux further through motor air gap, this result in needed for adjustable magnetic pulse magnetomotive force it is larger, increase coil volume.
