    摘要： A motor control system for controlling two or more motor groups includes a power converter that receives power from a power source and converts the power to an intermediate power and an intermediate power link coupled to the power converter. The motor control system also includes at least one motor driver coupled to the intermediate power link configured to provide power to one or more motors and a controller coupled to the power converter and the at least one motor driver. The controller is configured to cause the at least one motor driver to limit the amount of power delivered to the one or more motors based on the amount of power that the power converter can produce.

    摘要： A method of braking a washing machine from an operational speed to a zero speed is provided (as well as a washing machine incorporating the method) for a washing machine driven by one of a synchronous or asynchronous motor. Upon receipt of a stop signal, collapsing the motor rotating magnetic fields are collapsed for a predefined time period. After the predefined time period, DC braking voltage is applied to the motor stator windings at a controlled ramp-up rate to a fixed amplitude to generate a controlled ramped braking torque on the motor. The braking torque is applied until the motor is stopped.

    摘要： A method and device for protecting a power switching semiconductor inverter from thermal cycling is disclosed. The method compares the actual frequency of the inverter to a low fundamental frequency of the inverter and compares the actual current of the inverter to a continuous current rating of the inverter. A thermal cycling condition is detected if both (a) the actual frequency is lower than the low fundamental frequency and (b) the actual current is higher than the continuous current rating. A thermal cycling fault condition is detected when the inverter has been in the thermal cycling operating condition for a sufficient period of time to cause its present stress factor to exceed a predetermined rated stress factor.
