Abstract |
In induction motors supplied from PWM invertersrters appear additional phenomena which do not arise in normal supply from mains. These phenomena are: induced voltage at frame of
insulated motors; earth currents in grounded motors; shaft voltages; bearing currents. Trondheim These phenomena are caused by following reasons: existance of capacitance from stator windings to the rotor end stator iron and change of values of common mode voltages in motor windings. In the paper is present analysis of these phenomena and results of the researchs. |
