The starting-generating system that a kind of winding shown in Fig. 3 automatically switches, during as generator operation, three phase electric machine is sent out
Motivation, which drives, to be rotated at a high speed, and controller control double contact switch disconnects, the switching tube on three-phase inverter also contract fully, three-phase electricity
The end of pivot winding is hanging；It is whole that rectifying tube on rectifying tube and three-phase commutation bridge on three-phase inverter constitutes three single-phase H bridges
Current circuit, carries out rectification, the three phase electric machine exports direct current to a part of coil of three-phase windings.
Schematic diagram during the starting-generating system low speed generator operation that Fig. 4 automatically switches for a kind of winding of the invention.If
Engine is chronically at tick-over after starting, the induced electromotive force that the coil between three-phase commutation bridge and three-phase inverter is produced
Too low, it is impossible to ensure enough charging voltages, controller closes double-contact electromagnetic switch, the end of the three-phase windings of three phase electric machine

Series connection, three phase electric machine is full-bridge rectification, and output voltage is high, it is ensured that charging voltage during low speed.
The explanation of principle is operated to starting-generating system proposed by the present invention below.
When the starter-generator of the present invention is operated in generating state, armature winding has magnetic linkage to pass through.When outer rotor rotates,
The magnetic linkage of armature winding coupling changes, therefore the magnetic linkage of armature winding will change, so as to produce induced electromotive force.
Because now threephase armature winding centre tap is shorted together, therefore armature coil A1, armature coil B1 and armature coil
The induced electromotive force that C1 is produced is externally defeated after the diode rectification on the diode and three-phase commutation bridge on the first inverter
Go out.Armature coil A2, armature coil B2 and armature coil C2 have with vacantly, therefore without current versus output.If armature coil
The A1 number of turn is the half of A phase totals number of turns, therefore it is compared with traditional scheme, its output voltage also drop by half.
When the starter-generator of the present invention is operated in starting state, if passing to positive electricity to the increased phase winding of magnetic linkage
Stream, the phase winding reduced to magnetic linkage passes to reverse current, then motor can produce positive torque, driving engine rotation.Rising
During dynamic state, because the end of threephase armature winding is dexterously shorted together by double-contact electromagnetic switch, therefore armature coil
A1 and armature coil A2 series connection, i.e., all coils can be all energized, and its output torque is big.
Due to engine starting speed be 200r/min, and start with the rotating speed of rear engine can be raised to 700r/min with
On, therefore engine has an accelerator in the meantime, starter-generator is idle running without externally output in the process
Electric current, now double contact switch is closed, and will not produce big electric spark and voltage pulsation.
As the saying goes, main road is to letter.Seem more simply there is technology more to possess practical value, because simple thing
Reliability is high, cost is also low.The technology of the present invention have passed through what many thinkings were just drawn while it seem that simple really.
It is pointed out that the foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not
Be confined to this, any one skilled in the art the invention discloses technical scope in, the change that can be readily occurred in
Change and replace, should all cover within the scope of the present invention.Therefore, protection scope of the present invention should be with the claim
Protection domain is defined.
