There are numerous advantages of a permanent magnet synchronous generator which are enlisted below: 1: They are relatively secure and stable during their operation and don't require any external power supply, to excite their set-up.The permanent magnet synchronous generator is regarded as the primary source of electrical energy which is used commonly to convert mechanical output power of gas turbines, steam turbines, hydro turbines, wind turbines and reciprocating engines into electrical power for various purposes. 3: These generators offer high efficiency and power coefficient. The synchronous generator is excited by permanent magnet system with high energy or current carrying field windings. 6: In order to maintain the power factor, the condensers aren't required in synchronous generators as in the case of inductive generators. . Due to relatively higher number of poles, the permanent magnet construction would enable reduction in back iron and stator yoke. The development of low speed and innovative synchronous generators especially with permanent magnet excitation has received China 12v DC Motors Wholesalers attention from numerous individuals around the world. Commonly these generators are referred to as synchronous generators as they function at a synchronous speed, which equals the speed of rotor matches with the supply frequency. 5: Voltage regulation can be achieved in permanent magnet synchronous generators which aren't accessible in induction type generators. 2: The synchronous generators don't use slip rings as in case of other traditional generators, hence they are maintenance free and simple. 4: The synchronous generators are preferred to asynchronous generators especially for their high capacities, as asynchronous ones would consume enormous reactive power and thus they are suitable for smaller capacities.
