Turbo blower technology derived from breakthrough technology in high speed motor, high speed motor is called permanent magnet synchronous motor in terms.
Permanent magnet synchronous motor is great progress of motor industry when previous motor speed is few thousands, permanent magnet synchronous motor can reach more than 100000 rpm.
How could it do this?
1. Breakthrough of material used in motor.
2. Bearing technology breakthrough.
Here let's talk about bearing.
Before, bearing used for rotation machine is mechanical bearing and can be good for low rotation speed. later ceramic bearing is developed for high rotation speed at around 10000 rpm, but high cost and easy broken.
Air foil suspension bearing and magnetic suspension bearing is developed, which is completely friction free and get rid of parts contact.
Impeller is equipped directly on the shaft of high speed blower which make up the core parts of turbo blower.
Key words: turbo blower, permanent magnet synchronous motor, Air foil suspension bearing, magnetic suspension bearing
