An insulation seat of a slim reel-type brushless motor includes a ring-shaped bottom plate, an inner plate and an outer plate. The ring-shaped bottom plate has an opening. The inner plate is arranged around the opening. At least one upper locking element is protruded upwardly from the inner plate. At least one lower locking element is protruded downwardly from the inner plate. The upper locking element and the lower locking element are staggered. The outer plate is arranged around an outer periphery of the ring-shaped bottom plate. An accommodation space is defined by the ring-shaped bottom plate, the inner plate and the outer plate. A coil is disposed within the accommodation space. The at least one upper locking element of the inner plate is engaged with a first magnetic seat. The at least one lower locking element of the inner plate is engaged with a second magnetic seat.

Slim reel-type brushless motor and insulation seat thereof

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.

Motor and coil structure thereof

A fan including an impeller structure, a rotor structure and a stator structure is disclosed. The impeller structure includes a hub and a plurality of blades disposed around the outer periphery of the hub. The rotor structure includes a shaft and a magnetic element. The shaft is disposed through the magnetic element and connected to the hub. The magnetic element includes at least one terminal surface in the axial direction, and at least one receptacle is formed on the terminal surface. The stator structure is disposed around the outer periphery of the magnetic element. The heat dissipation system and the fan thereof can improve the reliability of the motor at high rotating speed effectively and prolong the lifetime of the shaft.
