SRMP Generator
(1) Generator terminal strip
(2) Main armature (stator)
(3) Main field (rotor)
(4) Rotor shaft
(5) Permanent magnet pilot exciter (PMG)
(6) Exciter
(7) Bearing
(8) FanThe SRMP generator has the following characteristics:
three-phase alternating current
brushless type
four pole or six pole designStationary main armature (2) bolts to the engine flywheel housing. A flexible plate type coupling connects rotor shaft (4) to the engine flywheel. Rotating main field (3) is keyed directly to the rotor shaft.The SRMP generator is a self-ventilated generator. Air enters the generator through screened orifices that are at the rear of the generator. Air exits the generator through screened orifices that are at the drive coupling end of the generator. Fan (8) attaches to rotor shaft (4). Bearing (7) supports the exciter end of the rotor shaft.Note: Some larger generators have two bearings. In this case, there will be a bearing at each end of the generator shaft.
