Description

Motor heat sink

This creation relates to a heat dissipation device for a motor, especially a heat dissipation device for a motor in which a fan blade is installed in the motor to improve the heat dissipation efficiency of the motor.

A motor is a device that converts electrical energy into mechanical energy and uses the generated mechanical energy to generate kinetic energy to drive a vehicle or equipment. The stator or rotor inside the motor is usually provided with a copper conductor coil, because the copper wire has a certain resistance Therefore, when the power is turned on, before the electrical energy is converted into magnetic energy, some of the electrical energy will be consumed by the resistance and dissipated in the form of thermal energy. When the thermal energy is transferred to the motor coil enameled wire, it will easily cause the outer polymer material of the enameled wire to be damaged, resulting in short-circuit damage to the coil. Cause the motor to be damaged.

As shown in FIG. 1, it is a perspective view of a conventional technique. A motor device 20 includes a yoke 21 outside. To avoid damage to the motor device, the yoke 21 is provided with a plurality of fins 22 for heat dissipation, but when the air field inside the motor device 20 does not flow, light The heat energy transmitted to the fins 22 on the yoke 21 by heat radiation for heat dissipation is limited, so the heat energy is easily accumulated inside the motor device 20 and is not easily dissipated, which may also cause damage to the motor device 20.

Based on the above reasons, there is still room for improvement in the conventional technology. In view of this, the creator is actively researching, adding years of experience in the development of related products, and after continuous experimentation and improvement, this creation has finally been developed.

The main purpose of this creation is to provide a heat dissipation device for a motor, which can improve the heat dissipation efficiency of the motor device and reduce the temperature rise caused by the motor device during operation.

In order to achieve the above object, the present invention provides a heat dissipation device for a motor. A motor device includes a yoke located in the middle of the motor device, a front cover is installed on one side of the yoke, and a rear cover corresponds to the front cover It is installed on the other side of the yoke, the yoke, the front cover and the rear cover are fixed by a combination of fasteners, the two bearings are installed in the front cover and the rear cover, and the stator is installed in the yoke The heat dissipation device of the motor includes: a rotor, installed in the stator, the rotor has a plurality of gas flow channels for gas in and out; a blade, installed in the rotor, When the rotor rotates, the fan blades are driven to rotate synchronously.

In order to further understand the characteristics and technical content of this creation, please refer to the following detailed description and drawings related to this creation. However, the drawings are for reference and explanation only, and are not intended to limit the creation.
