Explanation of type designation

1. PRODUCT INTRODUCTION OF YFKK ELECTRICMOTOR

YFKK series are medium-sized high-voltage three-phase asynchronous motor, are news products that our company made on the basis of digesting and absorbing similar design and manufacture technique in the world, we made a lot of improvements and innovations, the performance of the product is more optimized, the structure is more reasonable and reliable. YFKK motors’s design, manufacture, testing are in line with IEC standards.

YFKK motors frame base is welded with steel plate into box structures, and at the same time, I strengthened the hardness of 45º position of frame. At the top of the electric-motors, there can be choosed air-air or water-air cooler for heat exchange, easy disassembly and maintenance. The stator coil adopts copper wire with F grade insulation, heat resistance and pressure resistance are better. In production, multiple turn to turn impulse voltage tests and to-ground high voltage tests are performed, the stator is VPI treated with advanced German vacuum pressure impregnation solvent-free varnish equipment and process. Therefore, the motor has excellent and reliable insulation property, strong damp-proof property .Cold-rolled silicon steel sheet is adopted for iron core, unit volume loss is significantly reduced, the external press fitting structure of sator iron facilitates inserting coil and entire dip coating. Rotor has shaft collar structure,strengthening the rigidity of the shaft, increasing the area for air inletting of the rotor, cage rotor is adopted by cast aluminum technology.

2. PRODUCT USE OF YFKK ELECTRIC MOTOR

YFKK series electric motor has high efficiency, low noise, little vibration, reliable operation, easy installation and maintenance, etc. YFKK electrical motor can be used to drive various kinds of general machinery, such as: fan, water pump, compressor, crusher, cutting machine, transport machinery, etc., Available for mining, machinery industry, petrochemical industry, power generation and other industrial enterprises.

If the electric motor is used to drive blower, coal mill, rolling mill or winding machine, the customer should specify the use and technical requirements in order, we will use a special design to protect the reliable operation of the electric motor.
