Abstract

The intelligent ventilation structure comprises a horizontally arranged base, a stator is arranged in an inner cavity of the base, the outer side of the stator is attached to the inner side wall of the base, a plurality of annularly-arranged windings are arranged in an inner cavity of the stator, a rotor is arranged in the inner cavity of the stator, and the stator is provided with a plurality of windings. Through the arrangement of the temperature sensor, when the internal temperature of the machine base is normal, no response can be made, at the moment, the center shaft drives the multiple induced draft fans to rotate through the transmission rod, air is discharged from the rear side of the fan cover, when the internal temperature of the machine base is high, the temperature sensor can start the pump body, and the induced draft fans are discharged from the back side of the fan cover. The pump body pumps out cooling liquid in the water tank through the water inlet pipe, cools the winding, the rotor and the stator through the heat absorption copper plate and sprays the cooling liquid out of the water outlet pipe, and circulating cooling is achieved.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to an intelligent ventilation structure of a semi-driven permanent magnet motor. Background technique [0002] The permanent magnet motor is composed of stator, rotor and end cover, eliminating the need for collector rings and brushes that are prone to problems, improving the reliability of the motor operation; efficiency and power density. [0003] However, due to the high power density and narrow installation space of existing permanent magnet motors, the temperature rise is serious. The temperature rise of the motor directly affects the reliability and service life of the motor. Overheating also has the risk of failure of the windings and permanent magnets. Therefore, it is of great significance to design a good cooling structure for the motor to reduce the temperature rise of the motor. Contents of the invention [0004] In order to achieve the above object, ...
