Underground Coal Mines Permanent Magnet Synchronous Machine 1000kw

TBVF PMSM For Underground Coal Mines With Methane Explosive Mixture And Coal Dust

TBVF series low-speed and high-torque permanent magnet direct drive motors are suitable for the underground environment of coal mines with methane explosive mixture and coal dust. The drive mode of asynchronous motor + reducer directly drives the drum of the belt conveyor and shortens the transmission chain.
The motor cooling method adopts water cooling method, which has low temperature rise and low loss. The reducer with high failure rate is cancelled, which improves the reliability of the system and reduces the maintenance cost.

Applicable environment
● Ambient temperature -5℃～40℃;
● The altitude does not exceed 1000m, and the atmospheric pressure of the mine is (0.08～0.11) Mpa;
● The relative humidity of the air is not more than 95% (at 25℃);
● In environments where there is a danger of gas and coal dust explosions;
● The pollution level is 3;
● Places without significant vibration and shock.

Technical Features
1. Reliable operation and basically maintenance-free.
2. The torque is large, which solves the problem of heavy load starting and has no impact on the power grid.
3. When there is no load, reduce the running speed, reduce the wear and prolong the service life of the belt and idler.
4. It is convenient for centralized control and can be unattended.
5. It has functions such as early warning and pre-action to avoid accidents during startup.
