Abstract
A direct current permanent magnetism motor comprises a stator and a rotor, wherein the stator is fixed on a shaft, and an electrical grade sheet is arranged on the stator, an opening groove is arranged on the electrical grade sheet, windings are arranged in the opening groove, the outer surface of the electrical grade sheet is evenly provided with a plurality of permanent magnetisms, and the inner surface of the rotor is also evenly provided with a plurality of permanent magnetisms, slot gaps are arranged among the permanent magnetisms, and the windings are arranged in the slot gaps. Because the inner surface of the rotor and the outer circle face of the stator are evenly provided with permanent magnetisms and windings, and magnetic force exists between the rotor and the stator, which is beneficial for reducing the drag torque, and the starting performance of the direct current permanent magnetism motor of the utility model is effectively improved, and torque moment the output horsepower are improved.
Description
Technical field
The utility model belongs to electric motors, specifically a kind of direct current permanent magnet motor.
Background technology
Existing direct current permanent magnet motor comprises stator and rotor, on stator or the rotor winding is arranged, generate an electromagnetic field after the energising, magnetic field and magnetic field interphase interaction and realize circular motion, this electric vehicle motor needs bigger starting current when starting, consume more electric energy, especially under the condition of work of frequent starting, power consumption is bigger.
Summary of the invention
The purpose of this utility model provides a kind of direct current permanent magnet motor that improves startability.
The purpose of this utility model is achieved in that direct current permanent magnet motor of the present utility model, it comprises stator and rotor, stator is fixed on the axle, silicon steel sheet is arranged on the said stator, open slot is arranged on the silicon steel sheet, winding is arranged in the open slot, on the outer surface of silicon steel sheet, be provided with some permanent magnets uniformly, inner surface at rotor also is provided with some permanent magnets uniformly, and the groove crack is arranged between permanent magnet, and groove has winding in the crack.
Direct current permanent magnet motor of the present utility model because rotor inner surface and stator outer peripheral face all have permanent magnet and winding, has magnetic force between rotor and stator, helps to reduce the moment of resistance, can effectively improve the startability of motor, improves torque and power output.
Description of drawings
Fig. 1 is the structural representation of direct current permanent magnet motor of the present utility model.
Fig. 2 is the left TV structure schematic diagram of direct current permanent magnet motor of the present utility model.
Fig. 3 is the connection diagram of direct current permanent magnet motor stator of the present utility model and rotor winding.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2 and shown in Figure 3, direct current permanent magnet motor of the present utility model, it comprises stator 9 and rotor 5, and stator 9 is fixed on the axle 1, and silicon steel sheet 10 is arranged on the said stator 9, on the silicon steel sheet 10 open slot is arranged, winding 3 is arranged in the open slot, on the outer surface of silicon steel sheet 10, be provided with some permanent magnets 7 uniformly, also be provided with some permanent magnets 6 uniformly at the inner surface of rotor 5,6 of permanent magnets have the groove crack, and winding 4 is arranged in the groove crack.The electric machine controller that electric machine controller adopts Xieli Vehicle Components Co., Ltd., Jiaxing City to produce.
