Problems solved by technology
However, in the process of use, it was found that the motor has the problems of large internal ventilation resistance and poor heat dissipation. After various studies, it was found that the hot gas in the inner cavity of the motor frame enters the air duct and participates in the external circulation. The air circulation efficiency is low, and the cooling effect is not as expected

The invention discloses a double-suction divided flow super-efficient motor. The motor comprises a base, stators and rotors, the base comprises a cylinder body, an axial flow inner fan and a centrifugal inner fan are sequentially arranged at the non-driving end of a rotating shaft in the cylinder body, the cylinder body is provided with an inner air duct which protrudes outwards in the radial direction of the cylinder body and communicates with two ends of the inner cavity of the cylinder body, a first air inlet and a first air outlet are formed at two ends of the inner air duct respectively,an arc-shaped flow dividing baffle plate is arranged in the cylinder body and is in a hollow disc shape, the outer edge of the arc-shaped flow dividing baffle plate divides the first air inlet of theinner air duct into two parts, and the inner edge of the arc-shaped flow dividing baffle plate extends to one side, close to a rotor core, of the air outlet of the centrifugal inner fan. The arc-shaped shunting baffle plate reduces gas eddy and resistance loss in the cylinder body, so that the gas circulation efficiency in the cylinder body is improved. The axial flow inner fan enhances the air gap ventilation and heat dissipation of the motor stator and rotor, and enhances the heat dissipation effect.
Description
technical field [0001] The invention belongs to the technical field of motor explosion protection, and in particular relates to a double-suction split-flow ultra-high-efficiency motor. Background technique [0002] With the improvement of the energy efficiency level of motors, large-capacity, high-power-density, and small-volume motors are the development trend of explosion-proof motors, while low-efficiency, large-volume explosion-proof motors will withdraw from the market or be gradually eliminated. High-power motors are small in size and compact in structure at the same output power. The invention patent with the notification number CN 107994734 A discloses a high power density explosion-proof motor, including a base and an inner fan, a stator, and a rotor installed in the base. The inner fan is installed on the rotating shaft, and the front and rear ends of the base are respectively equipped with There are front end cover and rear end cover. The machine base includes a...
