Description
技术领域technical field

背景技术Background technique
传统压缩机由于受电机极限转速限制，只能采用增速齿轮箱等方式驱动，导致压缩机系统体积庞大、能耗高、寿命短、噪声污染严重。高速磁悬浮永磁电机通过直驱工作方式，可大幅度简化增速齿轮式系统结构，显著降低系统能耗、延长使用寿命，减小噪声污染，实现节能减排和环保。Due to the limitation of the limit speed of the motor, the traditional compressor can only be driven by a speed-increasing gearbox, which results in a large compressor system, high energy consumption, short life, and serious noise pollution. The high-speed magnetic levitation permanent magnet motor can greatly simplify the structure of the speed-increasing gear system through the direct drive mode, significantly reduce the energy consumption of the system, prolong the service life, reduce noise pollution, and achieve energy saving, emission reduction and environmental protection.
目前高速电机常用的冷却方式有空气冷却，液套冷却以及蒸发冷却，空气冷却的高速电机系统无漏液问题，维护方便，但冷却效率很低，电机体积大，液套冷却采用油或水- 乙二醇作为冷却介质，一般与转子自扇风冷合用，蒸发冷却采用 R123 等工质作为冷却介质，冷却效率最高，但维护困难，其中，液套定子冷却与自扇转子冷却相结合的方案采用最为广泛，技术也较为成熟。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 is used as the cooling medium, which is generally used together with the self-fan air cooling of the rotor. Evaporative cooling uses R123 and other working fluids as the cooling medium, which 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 The most widely used, the technology is relatively mature.
