Anti-explosion high-power high-speed motor and fan

Abstract

An anti-explosion high-power high-speed motor and fan comprise a motor rotor, a stator iron core and magnetic bearings installed on the motor rotor, wherein the stator iron core is installed on the motor rotor, positions, on the two sides of the stator iron core, of the motor rotor, are respectively provided with a fan blade and a motor winding adjacent to the fan blade, each fan blade is arranged between the stator iron core and each corresponding motor winding, the magnetic bearings are located on the sides, away from the stator iron core, of the motor windings, the stator iron core is segmented, and the outside of the stator iron core is provided with a heat pipe radiator which is provided with heat pipe fins. The anti-explosion high-power high-speed motor further comprises an anti-explosion shell arranged between the stator iron core and the heat pipe radiator. According to the anti-explosion high-power high-speed motor and fan, due to arrangement of the heat pipe radiator and the heat pipe fins, when a motor operates, heat produced by the stator iron core, the motor windings and the magnetic bearings is led out of the shell through the heat pipe radiator, then radiating is carried out through the heat pipe fins, heat in the device is exhausted and efficient radiating is achieved.

Description

technical field [0001] The invention relates to an explosion-proof high-power high-speed motor and a fan, in particular to a magnetic levitation explosion-proof permanent magnet synchronous high-power high-speed motor and a fan. Background technique [0002] At present, the commonly used cooling methods for high-speed motors include air cooling, liquid jacket cooling and evaporative cooling. The air-cooled high-speed motor system has no leakage problem and is easy to maintain, but the cooling efficiency is very low and the motor is bulky; liquid jacket cooling uses oil or water-ethylene glycol as the cooling medium, which is generally used together with the rotor self-fan air cooling; evaporative cooling Using R123 and other working fluids as the cooling medium has the highest cooling efficiency, but it is difficult to maintain. Among them, the combination of liquid jacket stator cooling and self-fan rotor cooling is the most widely used, and the technology is relatively ma...
