Analytical Determination of the Slot and the End-Winding Portion of the Winding-to-Rotor Capacitance for the Prediction of Shaft Voltage in Electrical Machines

Stockbrügger, Jan Ole; Ponick, Bernd (Basel : MDPI, 2020)

Common-mode voltage, caused by a 2-level inverter, is a source of discharge currents in motor bearings. Due to the capacitive coupling, between the stator winding and the rotor, an image of the common-mode voltage is ...
Analytical determination of the winding stator capacity for the prediction of high-frequency common mode current in electrical machines

Stockbrügger, Jan Ole; Ponick, Bernd (Wien [u.a.] : Springer, 2020)

The use of frequency converters provides easy variable speed operation of electric machines. However, parasitic and high-frequency phenomena occur in inverter-fed drives. As a result of the discrete switching states of the ...
Analytical determination of the winding-to-stator capacity for the prediction of high-frequency common mode current in electrical machines

Stockbrügger, Jan Ole; Ponick, Bernd (Wien [u.a.] : Springer, 2020)

Parasitic, high-frequency effects occur in electric drives during operation of fast-switching converters. In a two-point inverter, the mean value of the three output voltages is a non-zero common mode voltage due to the ...
