Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, electric generating motor double-purpose brushless synchro-electric machine is encouraged device 7, automatic voltage regulator AVR, motor synchronizing adjuster ASR, fan 3, support 4, front end housing 2, rear end cap 11 and bearing 12 by main frame stator 5, main rotor 6, brushless excitation machine stator 8, brushless excitation machine rotor 9, rotating rectifier 10, brushless throwing and is formed.Coaxial-type is arranged the main frame stator 5 and the brushless excitation machine stator 8 of band winding in the support 4, corresponding main rotor 6 and the brushless excitation machine rotor 9 of arranging the band winding with stator core in the rotating shaft 1, front end housing 2 is installed on the support seam of main frame stator side, install by bearing 12 between front end housing and rotating shaft, fan 3 is installed in the rotating shaft in the front end housing, rear end cap 11 is installed on the support seam of brushless exciter stator core side, install by bearing 12 between rear end cap and rotating shaft, the main frame stator has the harmonious wave winding WS of main winding W, the main rotor iron core has main excitation winding WF and starts winding WF, the brushless exciter stator core has a cover excitation winding WE, the brushless exciter rotor core has a cover AC Windings WJ, rotating rectifier XQ is installed respectively in the both sides of brushless exciter rotor core and device is encouraged in brushless throwing, the structure that rotating shaft is stretched for the front and back twin shaft, preceding shaft extension is installed the saxomat auto clutch that cooperates with prime mover can drive generator for electricity generation, and back shaft extension is installed the controllable clutch that cooperates with engine can drive the engine acting.
Do synchronous generator when operation when brushless synchronous machine, must carry out magnetoelectric induction, self-excitation running, whole process by each winding, each iron core, brushless exciter, device is encouraged in brushless throwing and automatic voltage regulator is realized.
Do synchronous motor when operation when brushless synchronous machine, must carry out asynchronous starting, synchronously throw encourage, the synchronous operation process, whole process by start winding, brushless exciter, device is encouraged in brushless throwing and the motor synchronizing adjuster is realized.
Synchronous motor is in the asynchronous starting process, start winding and enter work, make rotor begin asynchronous starting, rotating speed reaches 95% synchronous speed, simultaneously, the rotor magnetic pole winding can induce high-frequency high voltage alternating current, magnetic pole winding (Wf) insulation and the rotating rectifier (XQ) that connected produced impact and damage, brushless technology is at first wanted head it off, for this reason, 10 times of resistance (10Rf) in parallel on the magnetic pole winding to the magnetic pole winding, the restriction high-frequency high-voltage, simultaneously rotating rectifier can be subjected to induced voltage and conducting causes short circuit and damage, but string one rotation keyholed back plate (KX) between magnetic pole winding and rotating rectifier negative electrode link to each other with the rotating rectifier negative electrode but rotate the keyholed back plate negative pole, but rotation keyholed back plate positive pole links to each other with the magnetic pole winding for this reason, solved like this that magnetic pole winding insulation and rotating rectifier are not subjected to induction of high frequency high voltage shock problem in the asynchronous starting process, the asynchronous starting process is finished smoothly.
