Drivanordning med en styring for et løfteverk i en løfteanordning, særlig en kompakt løfteanordning

摘要

The method involves at least two parallel stator windings (3b,3c) and a rotor winding (3a) between them, all connected in series to a power supply (2), and both connections of the rotor winding are exchangeable to reverse the direction of rotation. In order to brake the motor, both connections of the rotor winding are exchanged within the series circuit and the series windings are short circuited. An Independent claim is also included for control circuit for stopping an electric motor operated with d.c. and/or a.c. current.
