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 assembling an electric drive system includes providing a power conversion assembly and coupling an electric power source and a motor to the power conversion assembly. The method also includes coupling a computing device that includes a processor and a memory device operatively coupled to the processor to the power conversion assembly. The method further includes configuring the computing device to record at least one measurement related to a speed of the motor. The method also includes configuring the computing device to calculate a power output limit of the power conversion assembly and limit the power output of the power conversion assembly by limiting torque induced by the motor as a function of the speed of the motor.
