An arrangement contains an asynchronous machine, which, in generator operation, is configured to feed electric power into an AC network. Accordingly, the asynchronous machine can be dual-fed by a modular multi-stage converter in a matrix configuration. The asynchronous machine has a rotor and the modular multi-stage converter is connected to the rotor of the asynchronous machine.

A motor control apparatus includes: a gate control voltage output unit that outputs a drive signal based on a corrected Hall edge that constitutes each of six Hall stages; a counter value acquisition unit that acquires a counter value which is represented by a time period between two Hall edges from the position detection signal; and a switching control unit that allows a value obtained by multiplying a previous counter value of each of the Hall stages by a preset correction coefficient to be a first delay time of each of current Hall edges and allows the gate control voltage output unit to output the drive signal based on each of the Hall edges obtained by correcting each of the Hall edges corrected by the first delay time by a second delay time that advances a Hall edge corresponding to a predetermined sensor among the plurality of sensors.

A drive system includes a power converter and a motor powered from the power converter via supply leads. An electromagnetically actuatable brake is disposed on the motor. The brake is able to be supplied and is therefore controllable from an AC/DC converter, which is powered via lines from a DC/AC converter that is powered and/or controlled by signal electronics of the power converter.
