Abstract

The present disclosure provides a motor including a base, a stator and a rotor. The stator is disposed on the base. The base includes a cylinder. There is a flange disposed on a side of the cylinder neighboring to the rotor. Fins are axially disposed on the flange, and the periphery of the flange has a breach. The breach is partially extended to the cylinder, and there is also a plurality of fins disposed in the breach. A plurality of air-guiding members are annularly disposed on the periphery of the rotor. The air-guiding members are connected to each other through a connecting rim. The fins on the flange and the air-guiding members of the rotor are both extended axially, thus the interference therebetween is avoided. When the motor rotates, the air-guiding members are able to drive the flow passing through the breach for achieving heat-dissipating effect.

Dependent claims

A motor comprising:

a stator having a base and a coil mounted on the base;
and
a rotor sleeved on the stator and rotating along an axis, wherein the rotor comprises a hub, a plurality of air-guiding members extended toward a direction away from the axis are annularly disposed on the hub, the plurality of air-guiding members are connected to each other through a connecting rim, and a through hole is formed between two adjacent air-guiding members and the connecting rim;
wherein the base comprises a flange and a cylinder, and the flange is disposed on a side of the cylinder neighboring to the rotor;
a breach disposed on the periphery of the flange;
and
an installation element having a first side and a second side opposite to the first side, wherein the first side is abutted against the flange,
wherein a plurality of second fins are disposed in the breach,
wherein via the breach, a second heat-dissipating flow flows from the second side to the first side of the installation element passing through the second fins, then, the second heat-dissipating flow flows out of the breach or passes through the through hole.
