Description
Technical field
The utility model belongs to motor field, more specifically to a kind of motor compressor motor.
Background technique
Traditional motor compressor is usually driven using permanent magnet synchronous motor due to power density, and utilizes permanent magnetism
Synchronous motor needs to match with sensor, controller, causes motor cost burden larger.
And use asynchronous machine or the current power density of switched reluctance machines smaller, and torque is smaller.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of at low cost, small volume, can increase torque and
The motor compressor motor of power density.
To achieve the above object, the utility model provides following technical solution: a kind of motor compressor motor, including
Rotor and stator, the rotor include iron core and the first winding, and the stator includes several magnetic pole groups, and the magnetic pole group includes forever
Magnet and at least one magnetizer are provided with the second winding on the permanent magnet and magnetizer, and several magnetic pole groups are along circle
Week is uniformly distributed.
The further permanent magnet is rare-earth permanent magnet or iron oxygen permanent magnet.
The material of the further magnetizer is silicon steel.
The further permanent magnet is magnetized by hallbach.
Further each magnetic pole group has a magnetizer or two magnetizers.
Compared with prior art, the utility model has the beneficial effects that increasing the power density of motor, the electricity of unit volume
Machine power square is bigger, and structure is simple, and cost is lower, is more suitable the power unit of motor compressor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model motor compressor motor.
Appended drawing reference: 1, iron core；2, the first winding；3, magnetic pole group；31, permanent magnet；32, the second winding；33, magnetizer.
Specific embodiment
The embodiment of the utility model motor compressor motor is described further referring to Fig.1.
A kind of motor compressor motor, including rotor and stator, the rotor include iron core 1 and the first winding 2, described
Stator includes several magnetic pole groups 3, and the magnetic pole group 3 includes permanent magnet 31 and at least one magnetizer 33,31 He of permanent magnet
The second winding 32 is provided on magnetizer 33, several magnetic pole groups 3 are circumferentially uniformly distributed.
The utility model is using asynchronous machine or switched reluctance machines as original shape, and wherein rotor structure does not make and changes, by stator
Middle part magnetic resistance changes.
When work, rotor rotation enhances the magnetism of permanent magnet 31, phase by the effect of permanent magnet 31 and the second winding 32
Cooperate magnetism stronger compared with original magnetizer 33 and the second winding 32, there is bigger attraction to rotor, increase torque, power
Density, rotor continue to rotate, and attract after magnetizer 33 and the cooperation of the second winding 32 with rotor, can avoid rotor in next position
When obstruction by permanent magnet 31 and the second winding 32, keep rotor to continue effectively to rotate, and compared to permanent magnet synchronous motor,
Cost is lower.
The present embodiment preferably the permanent magnet 31 be rare-earth permanent magnet 31 or iron oxygen permanent magnet 31, it is at low cost, comprehensive
It can be high.
The present embodiment preferably the magnetizer 33 material be silicon steel.
Preferably the permanent magnet 31 is magnetized the present embodiment by hallbach, can be optimized air gap magnetic density waveform, be subtracted
Small loss increases efficiency.
The preferred each magnetic pole group 3 of the present embodiment has a magnetizer 33 or two magnetizers 33.
Preferred each magnetic pole group 3 has a permanent magnet 31 and a magnetizer 33, i.e., the permanent magnet on entire stator
31 and magnetizer 33 successively alternately rule arrangement.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
