YRKK series high-voltage three-phase asynchronous motors have the advantages of compact structure, light weight, high efficiency, energy saving, low noise, low vibration, high reliability, long service life, convenient installation and maintenance, etc.
This series of motors is suitable for driving all kinds of fans, compressors, water pumps, crushers, chip machine tools, transportation machinery and other general machinery and other mechanical equipment. For motors, such as motors used to drive blowers, coal mills, rolling mills, hoists, and belt conveyors, relevant technical data must be provided when ordering, and a technical agreement must be signed as the basis for special design of the motor to ensure the reliable operation of the motor .
The motor adopts a box-shaped structure, and the frame is welded into a box-shaped structure from steel plates, which is light in weight and good in rigidity. There is a window on the top of the base, which is convenient for the maintenance of the motor on the one hand, and on the other hand, installing different coolers on the top can derive motors with different cooling methods and different protection levels.
The stator adopts an external pressure structure, the stator winding adopts F-class insulating material, the winding ends are reliably fixed and bound, and are treated by vacuum pressure impregnation solvent-free paint (VPI), so the motor has good insulation performance, high mechanical strength, moisture-proof Strong capability and long service life.
The winding rotor is treated with F-class insulating material and vacuum pressure impregnation solvent-free paint process VPI, and the rotor welding head and the wiring are all reliably insulated.
The bearing adopts two forms of rolling bearing and sliding bearing, which are determined by the power and speed of the motor. The protection level is IP54. The rolling bearing is equipped with a non-stop oil injection and discharge device.
The main junction box is placed on the right side of the motor (viewed from the shaft extension end), or it can be placed on the left side according to user requirements. There are separate grounding terminals inside and outside the junction box.
According to user requirements, temperature measurement devices can be added to important parts such as stator windings and bearings to facilitate on-site observation and long-distance monitoring to ensure safe and reliable operation of the motor.
