摘要：
A method of limiting current to a motor. The method comprising monitoring a speed of a motor, an input voltage of a controller, and a temperature of the controller. Determining a maximum current limit for the motor based on the monitored speed when the motor speed is below a speed threshold. Determining a maximum current limit for the motor based on the input voltage and the temperature when the motor speed is above the speed threshold and the input voltage is below an input voltage threshold. Determining a maximum current limit for the motor based on the temperature when the motor speed is above the speed threshold and the input voltage is above the input voltage threshold. Or determining a maximum current limit for the motor based on the monitored speed when the motor speed is above the speed threshold and the temperature is below a temperature threshold.
