Description

A kind of new forms of energy car AC permanent magnet synchronous motor
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of new forms of energy car AC permanent magnet synchronous motor.
Background technology
Now, people improve day by day to the cry that the new forms of energy car requires, and the development of new forms of energy car must drive the continuous progress of new forms of energy car motor manufacturing technology.Automobile motor is different from the power set of other field, has higher requirement,, efficient high, low speed high pulling torque little, in light weight as volume, the permanent power of high speed, speed-regulating range width etc., and then embody the comfortableness of new forms of energy car, improve market recognition rate and occupation rate.
Characteristics such as AC permanent magnet synchronous motor is little with its volume, performance good, efficient is high, reliability height obtain application more and more widely in new forms of energy car field.Motor can produce heat in use, if can not timely and effective heat is distributed and make the motor cooling, will influence service efficiency and the life-span of motor, even burn out motor.
Have the heat radiation of motor now, often rely on the heat sinking function of motor self, radiating effect is not good.Therefore, those skilled in the art is devoted to develop a kind of new forms of energy car AC permanent magnet synchronous motor of good heat dispersion performance.
The utility model content
The purpose of this utility model proposes a kind of new forms of energy car AC permanent magnet synchronous motor of good heat dispersion performance exactly.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts: a kind of new forms of energy car AC permanent magnet synchronous motor, comprise a casing, at described casing inner wall motor stator is arranged fixedly, in described motor stator, be provided with rotating p-m rotor, described p-m rotor is fixed on the machine shaft, described machine shaft is connected on the described casing by bearing and stretches out an end face of described casing, wherein, the other end that the casing end face that stretches out with described machine shaft is relative is provided with a cooling fan, and be arranged with in the shell of described casing cooling pipe and with water inlet and the delivery port of described cooling pipe conducting.
As further improvement of the utility model, described water inlet and delivery port all are arranged on the casing end face that has cooling fan, have made things convenient for external its circulatory system of cooling pipe, do not hinder the normal mounting of motor to use simultaneously.
As further improvement of the utility model, the circumferential lateral surface of described casing also is provided with the radiating fin to outer lug, further strengthens radiating effect, and can effectively be combined with enforcement cooling fan and cooling pipe.
As further improvement of the utility model, described cooling fan is arranged on the described casing by an installing rack is dismountable, further facilitates installing and using of cooling fan.
As further improvement of the utility model, described motor stator is provided with two stacked windings, has further improved the electric property of motor.
In sum, the utility model can act on the radiating efficiency that casing improves motor respectively by described cooling fan and cooling pipe, and simultaneously, cooling fan also can act on cooling pipe and radiating fin, can further improve the cooling rate of cooling pipe, improve the integral heat sink effect.
