The driving circuit outputs a driving current according to multiple control signals. The motor device drives a rotor unit to rotate according to the driving current, and includes a first sensor and a second sensor to sense the polarity of the rotor unit in different directions to generate polarity data. The control circuit receives the polarity data. When the polarity data is in a first state, the control circuit records a first maintenance time. When the polarity data changes from the first state to a second state, and a second maintenance time for the second state corresponds to the first maintenance time, the control circuit sets the polarity data to a third state, until the polarity data is changed from the third state to a fourth state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motor system and motor control method","description":"A motor system includes a driving circuit, a motor device and a control circuit.
