Abstract
(EN)
The invention provides a rotor for a doubly-fed generator. The number of conductors in each slot of the rotor is an even number greater than 2, the conductors in each slot is distributed into multiple columns, each column includes two conductors which are arranged up and down, and insulation material is filled between adjacent conductors. Accordingly, the invention further provides a doubly-fed generator and a wire winding method. With the rotor, the doubly-fed generator and the wire winding method of the invention, the consequences of rotor tooth flux density increase, rotor excitation current increase, motor efficiency reduction and the like can be avoided while the blocking open-circuit voltage can be increased.
