Specific implementation mode
Design feature：
Referring to Fig. 1 and Fig. 2, the utility model is permanent magnet DC motor, and permanent magnet portion is rotor, and iron core winding is stator
Part.It is that single annular is closed laminated iron that stator core and stator winding have apparent difference, stator core with conventional motors
Core, multiple stator winding are uniform, are symmetrically distributed in entire annular stator core.PM rotor includes central shaft 7, outside rotor
Ring 2, rotor inner ring 5, multiple outer ring magnets 3 and multiple interior ring magnets 4, central shaft 7 (are not drawn by bearing and stator base in figure
Go out) it is rotatablely connected, one end of rotor exterior ring 2 and rotor inner ring 5 is fixed on central shaft 7, is formed accommodate stator iron therebetween
The annular groove of core and stator winding, outer ring magnet 3 and interior ring magnet 4 are located in the annular groove and are separately mounted to rotor exterior ring 2
In rotor inner ring 5, the homopolarity in annular groove is opposite with interior ring magnet 4 for outer ring magnet 3, adjacent outer ring magnet 3 and adjacent inner ring

Electric current.
Rotary principle：
The stator winding of the utility model will not generate rotating excitation field, the magnetic field that stator winding generates as conventional motors
It is predominantly located in the stator core of annular, is attached to the magnetic flux of the permanent magnet (i.e. outer ring magnet 3 and interior ring magnet 4) on rotor
Circuit is：One end passes through rotor core (i.e. rotor exterior ring 2 and rotor inner ring 5), the other end to pass through stator winding and stator core
Form most short magnetic loop.Energization stator winding is acted in magnetic field by Ampere force, and according to Newton's third law, Ampere force is anti-
Rotating torque is formed to rotor is acted on.Among the utility model is completely in the magnetic field of rotor due to hot-wire coil winding, most
The mechanical efficiency for improving to limits winding makes 90% or more of winding coil total length directly participate in acting, greatly reduces
Loss caused by winding leakage field.
Electric circuit characteristic：
Due to all stator winding share an annular stator core, any moment clockwise be powered and counterclockwise
The number of windings that direction is powered is equal, and size of current is almost the same, so the magnetic flux very little in iron core, therefore energization stator
The impedance of winding also very little, close to Coil resistance (i.e. conducting wire internal resistance).The reduction of motor induction reactance can make the power factor of motor
Increase, thereby reduces the reactive loss of motor, improve the efficiency of motor.In order to reduce loss, this practicality to the maximum extent
It is novel that following measure is taken from circuit and structure design：1. stator winding must be even number and symmetrical；2. in rotor
The pole piece spacing N, S of the upper permanent magnet against stator winding is staggered and is even number set；3. the electric conduction of each stator winding
Stream direction is corresponding with vertically opposite permanent magnet polarity, and reversing current direction changes correspondingly；4. stator winding be distributed and forever
The pole polarity distribution of magnet will ensure their symmetry from structure, it is ensured that the stator winding number of two kinds of current directions is equal
And it also to be synchronized when synchronizing appearance in pairs, shutdown when being connected；5. switching off and on time point it has to be noticed that arc only where coil
All (current direction is answered with pole pair) could be connected in magnetic line of force vertical radiation area in degree line segment, and otherwise coil power turns off.
