Motor mainly is made of stator and rotor two parts, and stator has independently winding construction, and permanent-magnet steel is arranged in the rotor.Stator and rotor are made of the iron core that silicon steel plate stacking forms respectively.It is cylindric that stator is, and circle upwards is provided with groove in it.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the stator cylinder cavity, and certain space is arranged between stator and rotor.Stator has the winding of high strength enamelled wire coiled, and stator winding is connected with external power, outside source current by the time this electric current and the rotor permanent-magnet steel magnetic field interaction that produced, produce electromagnetic torque and drive the rotor rotation.
Stator winding is by constituting as the main winding of running winding with as the auxiliary winding that starts winding, winding is to insert an end of winding on the circle in two grooves in a plurality of grooves and insert the other end in stator in other two grooves, is wound with a plurality of windings in stator core.Therefore, be provided with the upper and lower of winding in the top and bottom of stator core, and be fixed with the top and bottom of fixed part in stator core.
That is, winding is divided into the upper end winding that is provided with on periphery unshakable in one's determination, and the lower end winding that is provided with below periphery unshakable in one's determination and be inserted between a plurality of grooves and connect the winding that is connected of upper end winding and lower end winding.
As shown in Figure 1, 2, stator core 1 is made up of a plurality of core lamination stacks, and the inside of stator core 1 is formed with radial a plurality of wire casing 2, is twining winding (not shown) in the inside of wire casing 2.In the inside of wire casing 2, be the center with the winding, be provided with a plurality of insulating trips (not shown), insulating trip is between core lamination stack and winding, insulating trip will play the insulation between winding and the stator core 1, can not cause short circuit, make that winding is unlikely to sustain damage because of short circuit.Between two wire casings 2, form a plurality of stator tooths 3.
Be formed centrally circular hole 4 in stator core 1, in circular hole 4 rotor be installed, in rotor center axle is installed, rotor and axle are fastenedly connected and rotate together.
But the wire casing of prior art is positioned at the inside of inner peripheral surface of the circular hole of stator core, electric machine winding difficulty, groove, the tooth of motor are interspersed simultaneously, make motor torque ripple in operation process big, thereby cause motor oscillating, noise big, electric efficiency reduces.
Summary of the invention
