Product Description

YRQ is the newest product by our company special for mines, a new series developed by combining a large amount of introduced technologies and our decades of experiences in design and manufacturing of motors for mines, which can be used to drive coal mill, rolling mill, winch, crusher and other machineries in mines.
 With a lot of advantages, including compact structure, slight vibration and low noise, high reliability, strong overload capacity and installation & maintenance convenience, Series YRQ is a new generation of high-performance motor special for mines. This series' mounting dimension is as same as the old Series JR11-15#, whose power level, mounting dimension and electrical performance meet GB755 Basic Technical Requirements for Rotating Motor.
By adopting a box-type structure and an integrated welded frame made of steel plate, the series has a good rigidity and a good shock resistance as well as a light weight. Ventilation pattern: natural air cooling, i.e. IC01; protection class: IP23; rated frequency: 50HZ; voltage classes: 380V, 3KV, 6KV, 10KV. We can design and customize motors with other voltage or frequency values (415V, 690V, 3KV, 10KV, 60HZ), high protection class: IP44, IP54 and to be used in special environment (high attitude, humid tropics, strong corrosion) as required by customers.
