Description

Technical Field

[0001] The utility model specifically relates to the technical field of cryogenic motors, and specifically is a new type of cryogenic-resistant motor. Background Technique

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is represented by the letter M in the circuit (D in the old standard); its main function is to generate a driving torque and serve as a power source for electrical appliances or various machines; while cryogenic motors usually work in a low-temperature environment. Currently, when traditional motors work in a low-temperature environment, they cannot achieve the effect of heat preservation; in this way, during long-term operation, due to the low temperature, it may cause the rotor inside the motor to freeze. When starting the motor, the motor needs to be started multiple times, which reduces the working efficiency of the motor.

[0003] In view of the above situation, we provide a new type of cryogenic-resistant motor. In this device, a roller is attached to the surface of the rotor inside the housing, and a heat preservation pipe is penetrated through the side wall of the roller. In this way, when the motor stops working, the heat preservation pipe effectively preserves the temperature generated between the rotor and the housing, so that there is a certain temperature inside the motor, effectively avoiding the rapid drop of the temperature inside the housing after the motor stops working; the rotor drives the roller to rotate, the roller fits with the anti-rolling frame, and the anti-rolling frame contacts the fixed ring through the rolling ball. In this way, when the rotor is working, the waste heat stored inside the heat preservation pipe can be effectively transferred inwards and outwards. The inward transfer effectively ensures the normal operation of the rotor, and the outward transfer through the anti-rolling frame, rolling ball and fixed ring effectively avoids the freezing of the housing, effectively ensuring the normal operation of the motor in a low-temperature environment.
