The Impact of Rotor Slot Wedge Material on Turbo-generator Parameters and Performance
The material of rotor slot wedge has a significant impact on performance of turbo-generators,including rotor losses and operating capacity.Consequently,the influence of the material selection for rotor slot wedges is crucial in a tur-bo-generator design.This study investigated the impact of rotor slot magnetic material on electromagnetic parameters such as synchronous reactance,rated excitation current,and air gap magnetic density distribution.Moreover,it compara-tively analyzed the effects of different slot wedge materials on electromagnetic parameters,out-of-step torque,short-cir-cuit torque,and power generation loss of the motor.The numerical results indicated that the use of magnetic slot wedges resulted in decreased synchronous reactance,increased rated excitation current,more uniformly distributed air gap mag-netic field,and altered corresponding generator losses.
