Motor construction with heat dissipation

The present invention is a heat-dissipating motor structure, in particular, a motor having multiple heat-dissipating paths to exert a more effective heat-dissipating effect, so that the inside of the motor casing can exhibit the highest output power of the motor due to the inability to accumulate heat. In turn, the operating efficiency of the motor is improved, and the service life of the motor is also extended.

In today's technology industry, the motor is a commonly used power object. However, whether it is a large motor with high power or a small motor with low power, it is easy to drive inside the motor casing after the motor starts the rotor. Accumulated high heat, due to the lack of a heat dissipation structure that can eliminate the high temperature generated by the motor operation in a timely manner, the high heat accumulated inside the motor will cause the magnetic force of the magnet to decay, and the running efficiency of the motor will gradually decrease, when the temperature rises. After a certain degree, the insulation of the enameled coil in the armature is more damaged, which causes a short circuit of the enameled coil to burn the entire motor, and even derive other dangers. In order to prevent such a deficiency, the currently widely used technology attaches a heat-dissipating fan to one end of the rotating shaft of the motor to suppress the rapid increase of the temperature of the motor during operation. However, this technique only allows the cooling fan to advance. The airflow is blown through the peripheral surface of the casing of the motor, and it is practically impossible to directly convey the forward airflow into the inside of the motor casing, which cannot effectively dissipate the inside of the motor at a timely time, so the inside of the casing of the motor used at this stage is The shortcomings of easy heat accumulation are still unable to overcome the solution.

The high temperature generated inside the casing during motor operation is eliminated in a timely manner.

Another main object of the present invention is to provide a heat-dissipating motor structure, the motor having at least one fully penetrating convection hole on the circumferential surface of the casing, so that the inside of the motor casing and the motor casing Externally, airflow can be generated. When the motor is operated, the high-temperature airflow generated in the internal space can be led out through the convection hole of the casing, and the internal space of the motor can be effectively cooled and cooled.
