Product Details

Brief Introduction 

 

Ex rated motor for underground coal mine is a kind of motor specially designed for coal mine environment, which has the characteristics of explosion-proof, moisture-proof and high-temperature-resistant etc. The motor adopts three-phase asynchronous working principle, which is able to operate stably under high load, high temperature and high humidity, and the IC411 cooling method is one of the highlights of the motor, which is able to effectively reduce the working temperature of the motor and prolong its service life.

 

The IC411 cooling method means that Ex rated motor is cooled by forced ventilation, which is able to keep the temperature of the motor within a safe range during high load operation. This cooling method introduces outside air into the motor through a built-in fan, which removes excess heat and ensures that the motor does not overheat during long periods of operation. This design not only improves the working efficiency of the motor, but also greatly extends its service life.

 

The motor adopts high-efficiency electromagnetic design, which can provide greater output power with lower energy consumption. Compared with traditional motors, Ex rated motor reduces energy consumption by more than 15% under the same load, which is in line with the requirements of modern coal mines for energy saving and emission reduction.
