Description

Single-phase capacitor operation asyn. motor
Technical field
The utility model relates to motor technology field, especially relates to a kind of single-phase capacitor operation asyn. motor.
Background technology
Present air compressor motor, electrical machine for vacuum pump, to its startability and rotation speed requirements relatively high, conveniently design of electrical motor thinking in theory, be difficult at high speed ensure startability, two characteristics are conflicting a kind of states.
Utility model content
The technical problems to be solved in the utility model is: the problem being difficult to ensure startability in order to overcome motor of the prior art at high speed, provides a kind of single-phase capacitor operation asyn. motor.
The utility model solves the technical scheme that its technical problem adopts: a kind of single-phase capacitor operation asyn. motor, comprise casing, axle, front end housing, rear end cap, stator, rotor, the two ends of described casing fixedly mount front end housing and rear end cap respectively, described stator is fixedly mounted in casing, described rotor is connected with axle, described rotor turns is arranged in stator, described stator is wound with enamelled wire, described casing, front end housing and rear end cap all have some ventilation holes, under the prerequisite ensureing integral rigidity structure completely, increase end cap and the enclosure vent hole of motor, and then further reduce electric machine temperature rise, 50k is reduced to by conventional 80k, improve the electric efficiency of 20%, the diameter of described enamelled wire wire diameter is 0.25mm, and the described enamelled wire number of turn is 498 circles, and enamelled wire wire diameter is optimized for minimum, and the number of turn is minimum, so realize motor stator low copper factor, reduce costs, described epitrochanterian skewed slot width is 1.8 times of rotor tooth well widths, by adjustment rotor chute, coordinate stator parameter designing, use the skewed slot of 1.8 times of rotor tooth well widths, optimize rotor harmonic performance, allow the startability of motor and breakdown torque performance reach most perfect condition further.
The beneficial effects of the utility model are: the utility model, under the prerequisite ensureing integral rigidity structure completely, increases end cap and the enclosure vent hole of motor, and then further reduces electric machine temperature rise, be reduced to 50k, improve the electric efficiency of 20% by conventional 80k; Enamelled wire wire diameter is optimized for minimum, and the number of turn is minimum, so realize motor stator low copper factor, reduce costs; Use the skewed slot of 1.8 times of rotor tooth well widths, optimize rotor harmonic performance, allow the startability of motor and breakdown torque performance reach most perfect condition further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is two-dimensional representation of the present utility model;
