New Rotor Structure Mitigating Vibration and Noise in Switched Reluctance Motor
Vibration and noise are the fetters which restrict the development of switched reluctance motor drive; this paper presented a new rotor structure which mitigates motors vibration and noise effectively. Based on the permeability theory, set holes on the rotor without filling materials in order to reduce the magnetic flux at the aligned position, further more, reduce the radial force amplitude from the motors noise origin. Also, finite element software is employed to analysis motors performance under different controlling modes including single phase excited mode, double phase excited mode. Parametric simulations are carried out to analysis how the key structure parameters influence the motors output performance. The simulation results form the basis of new structure optimization. And, a prototype 8/6 switched reluctance motor is tested, and the obtained test results show that motor with this kind of rotor structure keeps the output capability while has a less acoustic noise and vibration.
