Abstract:
1. A method of limiting current in an electric motor which is implemented for connection to a DC power network, said motor comprising: a rotor ( a stator having a stator winding arrangement ( a full bridge circuit ( an arrangement for sensing a current in the full bridge circuit ( one winding ( and from the second terminal ( and the method comprises the steps of: a) after a current in the full bridge circuit ( b) after that semiconductor switch has opened, of the totality of second semiconductor switch (LSL) and fourth semiconductor switch (LSR), in addition to the semiconductor switch already made conductive, also rendering the semiconductor switch not conducting at that moment conductive, in order to connect the terminals ( c) when that current has reached a lower value, once again switching on current delivery from the DC power network to the respective winding (
