The invention relates to a method for determining current in a polyphase machine connected to a DC voltage source.
The invention relates to a detection method for a polyphase machine (1) connected to a frequency converter (10), for adapting the frequency converter (10) to the connected machine (1) before an active productive operation.
A method for determining the rotational speed of a polyphase machine (DM) operating with field orientation and without a sensor is thus achieved, guaranteeing protection against tilting.
The invention relates to a method for actuating a multi-phase machine that is connected to a battery, said machine having a DC link that is provided with a DC link capacitor, phase windings, and for each phase a high side switch and a low side switch.

The invention relates to a method for controlling the active or reactive power output or input of an induction machine (1) in a coordinate system which is fixed for the winding.
The first and the second controller output variables are impinged upon with respective feedback variables which are functions derived from at least one time-dependent system variable of the induction machine.
According to the invention, a direct voltage (es) is initially supplied to the induction machine (DM) and a direct current actual value (is) determined, from which the stator resistance (Rs) is calculated.
