Abstract
The invention discloses a washer pump motor, which comprises a rotor and a magnetic shoe, wherein the arm width of each rotor sheet of the rotor is more than or equal to 2.4mm; the slot width of each rotor sheet is less than or equal to 1.4mm; and the centers of the inner and outer circles of the magnetic shoe are non-concentric. The washer pump motor has the advantages that by adoption of the non-concentric magnetic shoe and the rotor with narrow slots, the motor has high electromagnetic compatibility and low vibration noise, can completely meet the special requirements of the automobile industry and can be applied to a spraying washer pump for front and rear air windows of an automobile and a liquid circulating pump for automobile cooling.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of motor for automobile cleaning pump.
Background technology
Automobile cleaning pump and cooling are widely used in automobile industry with liquid circulation pump, and its power-actuated core derives from the motor that pump uses.Along with the development of automobile industry, motor is proposed following specific function require: during the work of a motor rotation, the electromagnetic interference of generation the smaller the better (electromagnetic compatibility EMC); During the work of b motor rotation, the vibration/noise of generation is the smaller the better; The reliability of service life of c motor rotation work is more high better.Find after deliberation, the strength member of these and motor: the motor magnetic tile of motor-field is provided and provides the rotor of the required magnetic field of motor path in close relations, and existing rotor rotor sheet arm wide be 2.0mm, the rotor sheet groove width is 1.8, the motor magnetic tile inside and outside circle center of circle is concentric, see Fig. 1, it can't guarantee that automobile industry is to the above-mentioned specific (special) requirements of motor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of washing pump motor for the above-mentioned deficiency that overcomes prior art, makes it reach the specific (special) requirements of automobile industry.
The present invention solves the problems of the technologies described above the technical scheme that adopts:
The washing pump motor comprises rotor and magnetic shoe, it is characterized in that: the rotor sheet arm of described rotor is wide 〉=and 2.4mm, rotor sheet groove width≤1.4mm, the round heart of described magnetic shoe inner-outer is non-concentric circles.
Inside and outside circle distance of center circle 〉=the 0.6mm of above-mentioned magnetic shoe.
Compared with prior art, the invention has the advantages that: adopt that non-its Electro Magnetic Compatibility is good with core circle magnetic shoe, narrow groove rotor, vibrating noise is little, the specific (special) requirements of automobile industry be can satisfy fully, front and rear windows of automobile water spray washing pump and automobile cooling liquid circulation pump can be applicable to.
Description of drawings
Fig. 1 is the structural representation of existing rotor.
Fig. 2 is the structural representation of embodiment of the invention rotor.
Fig. 3 is the structural representation of embodiment of the invention magnetic shoe.
Embodiment
Embodiment is described in detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 2, washing pump motor, its rotor adopt narrow groove structure a rotor sheet arm wide 〉=2.4mm; B rotor sheet groove width≤1.4mm.
As shown in Figure 3, its magnetic shoe of washing pump motor adopts non-with core circle structure, the distance 〉=0.6mm in the inner circle center of circle and the cylindrical center of circle.
Prove that after tested the performance of the motor that present embodiment obtains is as follows:
1. running noise of motor decibel (db) value reduces: under following equal conditions, and the unloaded noise decibel value decreased average 3 db:a same power supplies voltage 13.0V of motor; The b same rotational speed; The dynamic balancing of c rotor mechanical is identical. noise test case background noise 30 db.
2. EMC (electromagnetic compatibility) the harassing and wrecking levels (db) during motor rotation obviously descend.
According to the EN55025 standard, motor is under equal conditions being specified harassing and wrecking level and drop-out value such as the following table of respectively testing under the frequency range.
From showing and can finding out, although rise to some extent in 0.16MHz frequency range present embodiment EMC test harassing and wrecking level, but still in rating of electric machine limit value, and its EMC test harassing and wrecking level of most of frequency range declines to a great extent.
Claims (2)
1. the washing pump motor comprises rotor and magnetic shoe, it is characterized in that: the rotor sheet arm of described rotor is wide 〉=and 2.4mm, rotor sheet groove width≤1.4mm, the round heart of described magnetic shoe inner-outer is non-concentric circles.
2. washing pump motor according to claim 1 is characterized in that: the inside and outside circle distance of center circle 〉=0.6mm of described magnetic shoe.
