Electric motor units become bearing, and anti-gravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but is not needed in fact in electric motor units
On ontology again additionally increase component, bearing, rotor and stator are all that electric motor units itself are existing, simply by optimization stator around
Group increases extraction wire, produces unique anti-gravity Exciting Windings for Transverse Differential Protection structure, makes to have electric motor units as a huge bob-weight
Power bearing and a more good zero-g inertial flywheel, and cost only has some thousandths of of magnetic suspension bearing, this is exactly originally
The ingenious place of utility model.
It is right by the switch unit in anti-gravity control module when electric motor units need to restore power generation and driving function
The lead of anti-gravity Exciting Windings for Transverse Differential Protection switches over, in the stator winding that anti-gravity Exciting Windings for Transverse Differential Protection is recovered immediately to electric motor units.
The three of innovation：With driven compressor compressor
For air-conditioning, many times need to operate in low load condition, often by frequently stopping compressor, or control
The discharge capacity of compressor is realized；But best mode is to reduce compressor electric motor frequency of supply, reduces the rotating speed of compressor electric motor,
It can get best Energy Efficiency Ratio.But the price of frequency converter is relatively expensive, complicated and reliability is not so good as simple contactor
Control.Particularly with powerful compressor variable frequency device, price is total nearly close to Same Efficieney engine and generator
Valence, and change the rotating speed very simple of engine, also no at all increase any cost, is its basic function.
Existing engine and generator are made full use of in the utility model, by simply changing the hair in heat power compressor
Motivation rotating speed can easily change the working frequency of other compressors, simple and reliable.
In addition when compressor is used for high-speed permanent magnetic synchronous motor, such as centrifugal compressor, wheel speed is up to
15000-30000 r/min need, using extraordinary frequency converter, the 50 Hz or 60Hz supply frequencies promotion of external electrical network to be arrived
250-500Hz, price are even more than the price of high-speed permanent magnet motor.And the utility model is used, by using starting at a high speed
Machine, such as gas turbine, or using technology very ripe gear speedup case and High Speed Permanent Magnet Synchronous Generator, can easily obtain
The power supply of 250-500Hz.
