Axial Flow Fan Series with Permanent Magnet Synchronous Motor for Subway Tunnel
● The efficiency and power factor of the permanent magnet synchronous motor are higher than those of the level 1 energy-efficiency three-phase asynchronous motor, and the current of the permanent magnet synchronous motor is 10 - 15% lower than that of the asynchronous motor at the same power, making it more energy-saving.
● The motor has centralized winding, greatly shortens the length of the 'inactive part end' of the stator winding of the motor, shortens the length of the motor and reduces the weight of the motor, besides the length and weight of the fan can be further reduced.
● The use of specially designed permanent magnet materials can meet the high-temperature resistance requirements of 280 ℃/1h in subway tunnels.
Impeller diameter: 280 - 2800mm Air volume: 1000 - 900,000m3/h
Total pressure: 40 - 2800Pa
It is used for ventilation and smokes exhaust in subway tunnels.
