SRM PERFORMANCE AND DIAGNOSTICS ANALYSIS
Jakub Lorencki , Stanisław Radkowski
AbstractThe Switched Reluctance Motor Drive (depicted on Fig.1) is considered to be very attractive for Electric Vehicles or Hybrid Vehicles due to its variable speed control, low cost, rugged structure, reliable converter topology, high efficiency and simplicity in control This drive is well-known for its resistant structure for possible faults and wear because it is made from iron. It does not have permanent magnets, thus it does not convey its flaws, as: magnet demagnetization from opposite magnetomotive forces or high temperatures, high cost of rare-earth magnets, limited constant power range, danger of high magnetic forces from magnets, lack of high-speed capability and possible inverter failures. The SRM drive can be applied to military and strategic applications, as independent platforms, military vehicles, nuclear power plants where reliability and maintenance-free are the most essential aspects. Thus the drive with motor can be diagnosed for its fault resistance. In the Vehicle Institution at Warsaw University of Technology a special test station was designed in order to simulate some “real-life” faults and diagnose its resistance. The faults that can be forced are rotor and load imbalance and bearing damage, be means of special station configuration. The spectrum of current signal and vibration will be measure in order to determine the change of machine performance.
