Rotor structure with multiple pressure difference generating components

Abstract

The invention provides a rotor structure with multiple pressure difference generating assemblies. The rotor structure comprises a rotating shaft, a rotor body, a first pressure difference generating assembly comprising a plurality of first pressure difference generating blocks, and a second pressure difference generating assembly comprising a plurality of second pressure difference generating blocks. A first average width of the first differential pressure generating block has a first trend change in an extension direction. A second average width of the second differential pressure generating block has a second trend change in the extension direction. The first pressure difference generating block generates at least one first air flow which flows from the first pressure difference generating assembly to the second pressure difference generating assembly, and the second pressure difference generating block generates at least one second air flow which flows from the second pressure difference generating assembly to the first pressure difference generating assembly, so that the effects of two-way circulation of the air flow and heat dissipation and cooling are achieved.

Description

technical field [0001] The present invention relates to a structure, in particular to a rotor structure with a plurality of pressure difference generating components. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy and then into kinetic energy through electromagnetic induction. It is quite common and widely used in today's society. A motor usually includes a motor frame, a rotor structure and a stator structure. When the motor converts electrical energy into kinetic energy, the current will be conducted in the stator winding on the stator structure, thereby generating the current magnetic effect. However, during the conduction process, due to the resistance contained in the coil itself, the current will be lost, thereby generating excess heat energy. If the heat energy accumulates too much or the temperature is too high, it may damage the internal components of the motor and cause the motor to fail to operate normall...

Problems solved by technology

[0006] It can also be seen from the drawings that the wind speed levels in the internal passage PA121 almost fall between the wind speed levels 2 and -2, and there is no way to clearly see whether the airflow in the internal passage PA121 is two-way flow or both. flow from one end to the other

If it is flowing from one end to the other, it will cause a problem of higher temperature at the exit air flow

In addition, the wind speed level in the internal channel PA121 is also low
