Product Description

The series JR is a wound rotor 3-phase asynchronous motor meeting technical specifications of ministerial standard JB563-64, which can drive ventilator, compressor, water pump, crusher, ball mill, cutting machine, transportation machinery and other equipment and can be used as a primary mover in mechanical industry, power station and various industrial & miming enterprises. The ratings of the series are based on the values in continuous duty (S1): power 50HZ, rated voltage 220V/380V, 380V, 3000V & 6000V. And we can design motors with voltage rating 3300V/10000V as required by customers.This series adopts a protection class IP23 for its enclosure; a cooling mode IC01; and ordinarily adopts a structuring and mounting mode IMB3. And we can design it into a vertical mount as required by customers.The series JR guarantees, at rated voltage, the ration of the maximum torque to rated torque not less than 1.8.A starting rheostat must be connected into the rotor circuit in advance before the series JR is started, the starting mode based on short direct connection to rotor windings may not be allowed.

The deviation of the rated voltage of the YRQ ball mill motor does not exceed 5%, the allowable deviation of the frequency is 1%, and the sum of the absolute values of the deviations does not exceed 5%.

YRQ ball mill motor adopts rotor string resistance full-voltage start-up, which has the advantages of small starting current, large starting torque, high efficiency, low noise, low vibration, good ventilation performance, reliable operation and convenient installation and maintenance.

The company has large-scale laboratory, intelligent CNC winding machine, CNC rising machine, automatic wrapping machine, VPI high pressure vacuum immersion system, large-scale dipping paint drying furnace, 60 tons test platform, large vertical car, milling machine, grinding machine, Each type of dynamic balancing machine, double-feedback test and detection system with 6MW (12MW) motor and other motor production professional equipment more than 500 sets, sound mechanical equipment processing capacity, to lay a good foundation for customers to improve good quality motor products.

Main process flow of the motorMotor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint dryingElectronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balanceMotor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage

 

There are many types of motor products manufactured and sold by our company. The main products are high- and low-voltage three-phase asynchronous motors. The motor structure types include squirrel-cage type and winding type. Among them, high-voltage synchronous motors mainly support air compressors and mine ball mill equipment. use. We adhere to the service tenet of "focus on products, service with heart" and provide high-quality motor products to customers.
