STARTING SYSTEM FOR AN ELECTRICALLY-COMPENSATED CONSTANT SPEED DRIVE |
摘要 |
Prior generating systems utilizing electrically-compensated constant speed drives (ECCSD) have typically required a separate starter motor for starting a prime mover which supplies motive power to the ECCSD, thereby increasing the size and weight of the system. In order to overcome this problem, a generating system is provided with circuitry coupled to the electrical power windings of a permanent magnet machine (PMM) forming a part of the ECCSD for causing the PMM to develop motive power which causes an output shaft of a differential of the ECCSD to rotate at increasing speeds. When the output shaft of the differential reaches a predetermined speed, a generator coupled to the output shaft of the differential is supplied external or ground power which in turn causes the generator to operate as a motor and return motive power through the differential to the prime mover to start same and bring it up to operating speed. |
