1. Field of the Invention
This invention relates to a motor device, more particularly to a motor device capable of dissipating heat in an efficient manner.
2. Description of the Related Art
A conventional motor device has a motor casing that defines a chamber, a stator, and a rotor. The stator is fixedly disposed in the chamber, and the rotor is rotatably disposed in the chamber.
However, the conventional motor device suffers overheating, which can be detrimental to proper functioning of the motor device. Therefore, there is a need for a novel construction of a motor device that can facilitate efficient heat-dissipation.
SUMMARY OF THE INVENTIONThe object of the present invention is to provide a motor device that can overcome the above drawback of the prior art.
According to the present invention, a motor device includes a motor body and a set of heat-conducting pipes. The motor body includes a motor casing that defines a chamber, a stator that is disposed in the chamber, and a rotor that is rotatably disposed in the chamber. Each of the heat-conducting pipes has a heat-absorbing end that extends into the motor body, and a heat-dissipating end that is opposite to the heat-absorbing end and that extends outwardly of the motor body.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Referring to
In other embodiments, the heat-absorbing ends 21 of the heat-conducting pipes 2 extend between the stator 12 and the motor casing 11, as illustrated in
While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
