1. three-phase alternating-current motor
Change over switch among Fig. 3 is connected on one grade position, the three-phase alternating current supply socket connects power supply, three winding energisings of main stator (4), in main stator, produce the rotational stator magnetic potential, three-phase alternating-current supply links to each other with three inputs of rectifier I (6) by change over switch (2), rectifier I (6) has two outputs, and one is anodal, and one is negative pole.Direct voltage one tunnel after rectification is connected to Direct current power source socket through change over switch (6), outwards output dc voltage; One the tunnel directly provides the electric energy of excitation to the rotor electric supply installation; One the tunnel provides low-voltage electric energy through dc voltage regulator (7) to the rotor magnetic potential control device.Also to frequency, phase place, the phase sequential signal of the input input AC electricity of controller (8), they are basiss of reference of rotor magnetic potential control signal phase shift to three-phase alternating-current supply.
The work of power supply pulse-width modulator (14) in the rotor electric supply installation had both needed input dc power, the control of the pulse-width control signal that controlled again device (8) sends, and it passes to output power oscillator (15) according to the voltage of above-mentioned signal after with pressure regulation.The hunting power element of output power oscillator (15) is high-frequency power transistor or thyristor, and frequency of oscillation is got 20000～30000 hertz as far as possible so that noise is very little, loss is few, in light weight, volume is little.The output of power supply oscillator (15) is connected with the winding of power supply stator (16), make the power supply stator winding produce 20000～30000 hertz alternating magnetic field, thereby in the winding of power supply rotor (17), respond to alternating potential, after rectifier III (18) rectification, supply with each rotor direct current energy.
Controller (8) produces frequency instruction pulse and phase-splitting command pulse after with the frequency of the AC power imported, phase place calculation process, the frequency instruction pulse is sent a pulse when the first phase of each ac cycle is zero, pass to basic homophase cycle counter (9) by an output of controller; The phase-splitting command pulse is sent out a pulse when the first phase of each ac cycle is zero after continue and send remaining pulse in every interval (2 π)/(n), passes to basic phase cycle counter (9) by another output of controller (8).Basic phase cycle counter (9) is the stepping cycle counter, frequency instruction and phase-splitting that it is sent by controller instruct frequency locking to be locked in the frequency and the phase place of AC power, just frequency locking is locked in the stator magnetic potential, its continue one by one output stairstep signal and pass to phase shifter (10) by its each phase-splitting passage is continued one by one by each phase-splitting passage of phase shifter (10) and passes to transducing signal cycle counter (11).

(1) neutral gear
When primary shaft during with the rotation of a certain rotating speed, driven shaft and static load are connected with certain resistance square, and motor of the present invention pre-excitation does not have rotor magnetic potential, be in idling conditions, thereby driven shaft is static under the effect that hinders square.
(2) starting and acceleration
The electric energy that is produced by speed measuring device to rotor electric supply installation and the with light packs electric energy that provides small of putting of rotor magnetic potential system, because of the amplification of speed measuring device, satisfies the self-excitation power demand very soon after rectifier II (21) rectification.The main rotor magnetic potential is under the control of control signal, direction of rotation along rotor body is rotated with lower rotating speed (the automobile-used motor per second 1～5 of the vehicles changes), be the rotating speed of the rotating speed of rotor magnetic potential less than rotor body, at this moment the number of turns is more in the main stator winding, the thinner main winding in line footpath is produced induced potential by main rotor rotating magnetic potential cutting back, flow through the electric current of main stator main winding and the part that the rotor magnetic potential effect forms rotor rotation resistance square, the number of turns less (1～10 circle) in the main stator winding, the thicker main moment of torsion winding in line footpath by short switch (27) short circuit after, under the cutting of rotor rotating magnetic potential, produce bigger electric current, this forms the first of rotor rotation resistance square again, total resistance square of this two parts resistance square sum, rotor body is slowed down, promptly be that the speed governing element of differential gear train is slowed down, thereby make driven shaft starting and acceleration.
(3) speed stabilizing and speed change
The rotating speed that records driven shaft when speed measuring device is greater than setting going up in limited time of rotating speed, controller (8) sends signal reduces the electromagnetic torque between main stator (4), the main rotor (5), the rotor body rotating speed increases, thereby makes output speed decline and get back to the rotating speed interval that sets; If the load of driven shaft reduces suddenly or has added other actuating forces (as the vehicle descending) rotating speed still to be increased and needs when braking, then can make the rotation of rotor magnetic potential inverted rotor body direction of rotation by control signal, at this moment the effect of moment of torsion increases the rotor body rotating speed, form energy storage with the increase of rotor body kinetic energy, the generating of the main stator of main rotor magnetic potential cutting simultaneously winding, to charge in batteries or to other electrical installation power supplies, just can make output speed drop to desired numerical value.
In sum, the stepless speed change device that is combined to form of motor of the present utility model and differential gear train is that the moment of torsion that the size and Orientation of the electromagnetic torque by the sub-main rotor magnetic potential of control signal control motor main stator electric current is regulated the regulating element in the differential gear train makes driven shaft realize infinitely variable speeds.The size and Orientation of control electromagnetic torque can be realized by following measure: the pulsewidth of the signal controlling rotor electric supply installation that a. sends by controller (8) and the pulsewidth of transducing signal cycle counter (11), control the size of rotor magnetic potential with the size of adjusting rotor current; B. the direction of the signal controlling rotor magnetic potential that sends by controller (8) and the size of rotating speed; C. regulate the size of the short-circuit resistance that is serially connected with the main moment of torsion winding in the main stator winding.

When external electrical network substantially just often, the rotor magnetic potential control device just plays compensator and pressurizer, the size that can regulate positive and negative virtual power, the size that also can regulate real merit power.
When external electrical network voltage descends or load when big load impact occurring in short-term, the rotor magnetic potential control device becomes negative with the merit angle θ of motor at once, makes motor make generator operation, descends or big in short-term load impact with compensation network voltage.When external power grid destructive major break down occurs or has a power failure, to control sub-magnetic potential control device and immediately motor and external power source are cut off, this moment, motor can continue to be enough to start stand-by generator group or power set to load power supply 1～15 minute, to guarantee to continue power supply.This motor cuts off the energy of powering behind the external power source and is provided by the stored rotation function of flywheel, though the rotating speed of flywheel constantly reduces because of the power supply power consumption, but, the characteristics of motor of the present invention control by the rotor magnetic potential control device because being amplitude, rotating speed, frequency and the phase place of rotor magnetic potential, irrelevant with the rotating speed of rotor body or flywheel, so voltage, frequency and the phase stabilization of generating.
