More Information
Summary:The utility model discloses a DC brushless multi-speed motor, and is mainly technically characterized in that the DC brushless multi-speed motor is provided with at least two groups or more than two groups of windings. In the case of many motor windings, a unit current produces a large torque, and the rotation speed is low, so the climbing capacity is strong. In the case of few windings, a unit current produces a small torque and the driving speed is high.
