Abstract
The utility model provides a kind of claw-pole type rotor electromotor, comprise stator, rotor, be the 8-12 utmost point, stator winding is a three-phase four-wire system, it is characterized in that: this rotor is a claw-pole type, the magnetic pole that is rotor is divided into two parts up and down, and every part all is claw-like, and wherein the top pawl down, the lower part pawl up, two parts magnetic pole is inserting state, is soft iron core in the middle of the magnetic pole, above the iron core around magnet exciting coil.This motor claw-pole type rotor minor structure compactness that takes up room can be saved a large amount of copper cash and silicon steel sheet; 8-12 utmost point motor coil winding span is little, so the yoke of stator can do very thinly, can save raw material and can alleviate body weight again, and the claw-pole type stator structure is simple, and is easy to manufacture, easy to utilize.
Description
Technical field: the utility model relates to a kind of motor.
Background technology: at present, widely used motor, no matter its rotor is squirrel-cage or Wound-rotor type, all exists the high and big defective of body weight of consumptive material, want under with the situation of constant power, not only to reduce manufacturing cost but also save material, so just must structurally improve.
Summary of the invention: task of the present utility model is exactly at the problems referred to above, and a kind of claw-pole type rotor electromotor is provided, and this motor is not only simple in structure, and body weight is light, and easy to manufacture, saves material, and reduces production costs.Its technical solution is: a kind of claw-pole type rotor electromotor, comprise stator, rotor, be the 8-12 utmost point, stator winding is a three-phase four-wire system, it is characterized in that: this rotor is a claw-pole type, the magnetic pole that is rotor is divided into two parts up and down, and every part all is claw-like, and wherein the top pawl down, the lower part pawl up, two parts magnetic pole is inserting state, is soft iron core in the middle of the magnetic pole, above the iron core around magnet exciting coil.Advantage of the present utility model mainly is: (1) claw-pole type rotor minor structure compactness that takes up room, can save a large amount of copper cash and silicon steel sheet; (2) 8-12 utmost point motor coil winding span is little, so the yoke of stator can do very thinly, can save raw material and can alleviate body weight again; (3) the claw-pole type stator structure is simple, and is easy to manufacture, easy to utilize.
Description of drawings: Fig. 1 is a claw-pole type rotor structure schematic diagram of the present utility model.
Embodiment: as shown in Figure 1, the claw-pole type rotor electromotor that the utility model provides comprises stator, rotor, be the 8-12 utmost point, stator winding is a three-phase four-wire system, it is characterized in that: this rotor is a claw-pole type, and promptly the magnetic pole of rotor is divided into two parts up and down, every part all is claw-like, wherein the top pawl down, the lower part pawl up, two parts magnetic pole is inserting state, is soft iron core in the middle of the magnetic pole, above the iron core around magnet exciting coil.
