Description
Affiliated technical field
The utility model relates to a kind of high voltage and high power density iron-core less motor, and this motor does not have iron core, and therefore, this motor is the efficient height not only, and caloric value is extremely low.This electric machine structure is simple, the heat balance condition is good, is particularly suitable for making the high voltage and high power density electrical machine.
Background technology
Conventional motors all has bigger copper loss and iron loss, and this has influenced the raising of electric efficiency widely, and amount is excessive to make also that the motor feels hot, influences its dependability.
Summary of the invention
In order to overcome the big shortcoming of conventional motors copper loss and iron loss, the utility model provides a kind of high voltage and high power density iron-core less motor.
The technical solution of the utility model is:
Stator is made tubbiness, motor coil is fixed among the stator, stator closely is connected with the motor metal shell, thereby increased the thermal capacitance of stator coil greatly and by the ventilating heat dissipating hole on the motor metal shell that exposes the heat of coil is distributed, this measure can improve the power density of motor greatly.
With stator that the motor metal shell links to each other outside be provided with rotor, rotor is a twin-tub shape structure, rotor is made by the iron material, on the rotor medial surface, be fixed with some to permanent magnet, by attracting each other and supporting and keep suitable air gap with stator coil by rotor.Stator does not have core structure for the wire-wound tubbiness, drives the rotor that is supported on the bearing and rotate and power output when energising.
The beneficial effects of the utility model are:
1) therefore no iron core does not have iron loss.
2) internal resistance of tubbiness stator coil is extremely low, so caloric value is little.
3) two-sided yoke can be gathered magnetic by the iron motor stator, has improved the magnetic energy utilization rate.
4) electric efficiency height.
5) the output torque is big.
6) no slot effect.
7) rotating speed is steady.
8) moment of inertia is little.
Further specify specific structural features of the present utility model below in conjunction with Figure of description and embodiment.
