Analytical determination of the slot portion of the stator-to-rotor capacitance for the prediction and reduction of bearing voltage in electrical machines

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

Fast-switching inverters enable a low-loss and low-noise variable-speed operation of an electrical machine. The trend towards inverter-fed drives is further strengthened by falling costs. However, the steep voltage flanks ...
Analytical determination of the slot portion of the winding rotor capacity for the prediction of bearing voltage in electrical machines

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

The number of inverter-fed motors is increasing due to the good controllability of the motor and the cost, which by now is low. As a result of the discrete switching states of the power transistors, the average of the three ...
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 ...
Analytische Bestimmung parasitärer Kapazitäten in elektrischen Maschinen

Stockbrügger, Jan Ole (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)

Die Anzahl umrichtergespeister elektrischer Maschinen steigt aufgrund der guten Regelbarkeit des Motors bei mittlerweile niedrigen Anschaffungskosten. Infolge der diskreten Schaltzustände der Leistungstransistoren ist der ...
