Synchronous vs. induction alternator

An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC induction motor usually can be used as a generator, without any internal modifications. Because they can recover energy with relatively simple controls, induction generators are useful … WebAnswer (1 of 9): The same as the differences between a synchronous motor and an induction motor, because they’re the same things. A synchronous motor/generator has a rotor with either a permanent magnet or an electromagnet energized through slip rings from an external DC source. An induction mot...

WebMay 23, 2024 · 4 Answers. The synchronous speed of the rotor in RPM N = 120f/P where f is the frequency of the stator current and P is the number of poles. The operating speed No = N - Ns where Ns is the slip speed. The frequency of the rotor current fr = Ns x P/120, so fr = 0 if the slip is zero. If the operating speed is zero, Ns = N and the frequency of ... WebFitting a PMG will increase the length of the alternator. So we'll show you the difference on a Stamford HCI544D1 alternator and what the PMG looks like. So this is the non-drive end of the alternator as it arrives, without the PMG fitted.
