Abstract
A motor comprises a coil structure and a plurality of magnetic materials. The coil structure includes three winding groups, each of which has a plurality of winding portions. The winding portions have an interval therebetween, and are electrically connected by a wire. The magnetic materials are disposed adjacent to the coil structure and corresponding to the winding groups. Accordingly, the motor has more magnetic materials within the same bending angle of the enameled wire, so that the motor can output larger torsion and power to enhance the motor efficiency.
Claims11
A motor, comprising:
- a coil structure, including three winding groups, each of which has a plurality of winding portions, wherein the winding portions have an interval therebetween, and are electrically connected by a wire;
