Need to make to change, there is tooth socket on two sides and is fixed on base embedded with the discoid iron core periphery of coil, magnetic field also axially across
Iron core.
The course of work (principle) is as follows:
The connection of stator winding guarantees that the stator core of opposite face after being powered forms opposite polarity magnetic field, and rotor disk is also that height is led
Magnet steel just forms the magnetic field for passing through rotor disk, and when leading to three-phase alternating current in stator winding, this passes through the magnetic field of rotor disk
It will rotate, rotor speed generates electricity with regard to induced current, electric current and magnetic fields in rotor disk when rotating excitation field revolving speed difference
After magnetic force can in shaft output torque to by electromagnetic energy be mechanical energy.
Conventional motors winding is conductive, and iron core magnetic conduction, the electric current in iron core for having alternating magnetic field to pass through all generates loss, this hair
Bright magnetic field is not turned directly through rotor disk, all work done electric currents of the electric current of induction, substantially without non-work done electric current, because
The innovation of this principle of the present invention is that both magnetic conduction is also work done current conductor to solid rotor disk, rotor disk do not need lamination and setting around
Group, structure can greatly simplify.The resistivity of steel is about 5.6 times of copper and 3.5 times of aluminium, but is led under solid disc rotor condition
Electric area is much larger than independent winding, and the difference of resistivity can be fully compensated in the increasing of conductive area when rotor disk has suitable thickness
Away from rotor is smooth circular plate, and windage loss is small, and bearing spacing also substantially shortens, and mechanical loss is smaller than conventional motors, therefore electricity
Engine efficiency can be improved.In the case where cost allows and motor is needed to have greater efficiency, radial tank is processed on disk, is processed
Copper or aluminium are filled after inside and outside two parallel connected end annular grooves, form a grill-shaped winding, rotor disc thickness can be thinned and improve electricity
Engine efficiency.
It magnetizes after adding permanent-magnet steel, motor just becomes permanent magnet synchronous motor, and motor is by magnet steel excitation at this time, and rotor is without electricity
Stream, rotor portion do not have a resistance loss, motor power factor can achieve 1.0 thus stator current it is also much smaller, the ruler of motor
Very little and weight reduces, and efficiency will have very big promotion.Motor asynchronous starting, permanent magnetic field can lead motor when revolving speed is close to synchronous rotational speed
Enter synchronization, motor desynchronizing when having more than the load disturbance of maximum synchronous torque, motor enters asynchronous operation, does not surpass in load disturbance
Motor asynchronous operation when crossing maximum asynchronous electromagnetic torque, is returned to synchronous operation after disturbance, motor has very high reliability.
The present invention is a kind of and the entirely different motor of conventional motors structure, can be in asynchronous machine field and permanent-magnet synchronous
Motor field is all applied, and novel point first of the invention is that operating fields are become axially from radial；Second is also most important
Be some rotor using the homogeneous solid slab without lamination, solid slab can not only make iron core magnetic conduction but also can make in the structure of the present invention
Winding is conductive, and can simplify structure reduces cost；The efficient operation of magneto can be taken into account after the embedding permanent-magnet steel of third solid slab
Starting with asynchronous machine is convenient.No permanent-magnet steel solid rotor alternating current generator can replace cage induction motor；Band permanent-magnet steel is real
Heart rotor has the characteristics that permanent magnet synchronous motor is efficient in unloaded and certain power bracket, while can be as cage induction motor
It equally starts, needs complicated starting device to apply than conventional synchronization motor more convenient and economical；Tandem motor can be applied
In original long iron core high-capacity and high-speed motor field, the present invention will bring the big variation of electric machine structure and weight.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
