Abstract
The utility model provides an armature assembly of an evaporation blower fan, comprising a rotating shaft, a rotor core, a rotor winding and a commutator arranged on the rotating shaft. The commutator comprises an insulation substrate and several commutator segments distributed on the circumferential surface of the insulation substrate and combined with the insulation substrate. Adjacent commutator segments are mutually insulated through separation troughs, one end of each commutator segment is provided with a thread drawing hook, and the periphery of the rotor core is provided with a plurality of rotor core grooves uniformly distributed. The armature assembly of evaporation blower fan is characterized in that the separation troughs on the commutator are corresponding to the rotor core grooves one to one. According to the armature assembly of an evaporation blower fan, the separation troughs on the commutator are corresponding to the rotor core grooves one to one, the production efficiency of the motor is raised, the magnetic field waveform is improved when motor commutation happens, electromagnetic noise of the motor is reduced, commutation spark is reduced, and the service life and the reliability of the motor are raised.
Description
Technical field
The utility model belongs to the evaporation fan field, is specifically related to a kind of armature assembly of evaporation fan.
Background technology
Existing evaporation motor is mainly to adopt permanent magnet DC motor to drive impeller of blower to come Cooling Air-conditioning System.Permanent magnet DC motor adds that direct voltage just starts working, and whole system is simple in structure, compact, is widely used in air conditioning for automobiles.In traditional permanent magnet DC motor, the commutator hook of its rotor and rotor core groove position are corresponding, have that commutation spark is large, the not high defective of production efficiency of rotor.
The utility model content
The utility model provides a kind of armature assembly that can reduce commutation spark, improve the evaporation fan of rotor efficiency for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of armature assembly of evaporation fan, comprise rotating shaft, rotor core, rotor winding and be installed in commutator in rotating shaft, described commutator comprise insulating body and be distributed in insulating body side face and with some commutator segments of its combination, between adjacent commutator segment, by the separation trough mutually insulated, an end of each commutator segment is provided with wire-hanging hook; Be evenly equipped with a plurality of rotor core grooves on the excircle of described rotor core; It is characterized in that, the separation trough on described commutator is corresponding one by one with rotor core groove position.
Further, also be provided with circlip for shaft in described rotating shaft.
Further, be provided with balance mud on described rotor winding.
The armature assembly of evaporation fan described in the utility model has improved the production efficiency of rotor by the separation trough on commutator is corresponding with rotor core groove position, and the field waveform when having improved motor commutation has reduced the electromagnetic noise of motor; Reduced commutation spark; Improved the life and reliability of motor.
