| Abstract: | The brushless doubly-fed machine (BDFM) is a new type of induction machine, with good application prospects. It is very suitable for driving windmills or water pumps to perform speed-adjusting and energy-saving operation. In this paper, the operational principle of BDFM is analyzed in detail and the equations of the rotor speed, power and rotor frequency are derived. After the harmonic analysis, the approach to decrease higher harmonic is presented by using cross-short-pitch stator windings and adjusting the distributions of rotor bars. Finally, the theory and method of electromagnetic design for BDFM are discussed in detail with examples. |
