MOTOR ASSEMBLY AND HOIST DRIVE

摘要

A motor assembly comprising a three-phase asynchronous machine equipped with three stator phases (L1, L2, L3), a capacitor assembly (10) to establish self-excited generator operation of the asynchronous machine, a load resistor assembly (12) to establish resistive load for self-excited generator operation of the asynchronous machine, and a load resistor switch means which is arranged to connect the load resistor assembly (12) to the stator phases (L1, L2). The load resistor assembly (12) is asymmetrical.
