The method includes the following steps. An actual speed and an actual current of a motor module are sensed by a sensor module. An adjusted speed is kept at a set speed or a speed curve by a speed adjusting circuit. A control signal is provided by a feedback control circuit according to a difference between the adjusted speed and the actual speed. The control signal is converted to a current to drive the motor module, such that the actual speed is kept at the adjusted speed. When the actual speed is decreased and the actual current is increased to a limited current value, a setting parameter of the feedback controller is changed according to the limited current value, such that the control signal enters a saturation state and the actual current is kept at the limited current value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motor apparatus and motor control method","description":"A motor apparatus and a motor control method are provided.
