Asynchronous Operation Analysis of Brushless Doubly-Fed Machine with Magnetic Barrier Rotor

Article Preview

Abstract:

To restrain the influence of armature reaction, flux barriers is added to rotor structure and enhance the output power ability of brushless doubly-fed machine. Design scheme of brushless doubly-fed machine with barrier rotor is provided. Based on field-circuit coupled finite element method, The asynchronous operation performance of brushless doubly-fed machine with barrier rotor is studied under the condition of no-load, including adjusting voltage adjusting speed and series resistance adjusting voltage. The prototype is carried out on the condition of no-load asynchronous operation; comparison analysis of simulation speed values and tested speed values is realized. The designed machine is reasonable and reliable.
