The motor control system may include a motor, a power factor correction (PFC) circuit providing current to the motor, and a signal processor. The PFC circuit may limit current provided to the motor based on an output voltage sensed by the PFC circuit. The signal processor may sense input voltage of the PFC circuit to determine a power limit, then compare sensed or calculated drive power of the motor with the power limit. If the drive power sensed or calculated is greater than the power limit, the signal processor may output a signal for reducing the drive power to the power limit. Limiting the drive power provided to the motor limits or decreases a speed of the motor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motor control system and method for input current protection","description":"A motor control system for adjusting motor speed if a current overload condition occurs.
