A method of switched reluctance motor acoustic minimization

Acoording the issue of acoustic with switched reluctance motor(SR motor), we analysed two resourse of the acoustic first. Analyzing the different for two windings providing electric power at the same time and one winding providing electric power at the same time. We get conclusion that two phase windings providing electric power would minimizing acoustic. Experiment with a 5.5 KW Switched Reluctance Motor for four phase prove that the designed SRD with two windings providing electric power at the same time and change angle controlling has excellent minimizing acoustic character.
