TBVF series low-speed high-torque permanent magnet direct drive motor is suitable for underground coal mine environments with explosive mixtures of methane and coal dust. The motor adopts ExdⅠMb explosion-proof grade. It is a low-speed high-torque permanent magnet synchronous motor dedicated to underground mine belt conveyors. Asynchronous motor + reducer drive mode directly drives the drum of the belt conveyor, shortening the transmission chain.
The motor cooling method is water-cooled, with low temperature rise and low loss. Eliminated the reducer with high failure rate, improved the reliability of the system, and reduced maintenance costs.
Applicable environment
● Ambient temperature: －5 ℃ ～ 40 ℃;
● The altitude does not exceed 1000m, the atmospheric pressure of the mine (0.08 ～ 0.11) Mpa;
● The relative humidity of the air is not more than 95% (at 25 ° C);
● In environments where there is a danger of gas and coal dust explosions;
● Pollution level is 3;
● Location without significant vibration and shock.
Technical characteristics
1. Reliable operation and basically maintenance-free.
2. The high torque solves the problem of heavy-duty starting and has no impact on the power grid.
3. When no-load, reduce the running speed, reduce wear and prolong the service life of the belt and idler.
4. Convenient centralized control and unattended operation.
5. It has functions of early warning and pre-action to avoid accidents during startup.
