MOTOR ASSEMBLY AND HOIST DRIVE |
| 摘要 |
A motor assembly includes a three-phase asynchronous machine equipped with three stator phases, a capacitor assembly to establish self-excited generator operation of the asynchronous machine, a load resistor assembly to establish resistive load for self-excited generator operation of the asynchronous machine, and a load resistor switch which is arranged to connect the load resistor assembly to the stator phases. The load resistor assembly is asymmetrical. |

1. A motor assembly comprising:
a three-phase asynchronous machine equipped with three stator phases; a capacitor assembly; a capacitor switch for symmetrically connecting the capacitor assembly to all three stator phases to establish self-excited generator operation of the asynchronous machine; a load resistor assembly to establish resistive load for self-excited generator operation of the asynchronous machine; and a load resistor switch arranged to connect the load resistor assembly to the stator phases, wherein the load resistor assembly is asymmetrical. |
