Product Introduction
This series of motors are suitable for driving all kinds of general machinery such as fans, compressors, water pumps, crushers, chip cutting machines, transportation equipment, etc. At the same time, it is used as the prime mover in various industrial and mining enterprises such as mines, machinery, petroleum, chemical industry, power stations, ships, etc.
This series of motors adopts Class F insulation, temperature rise is assessed according to Class B, rated frequency is 50Hz, and rated voltage is 3kV, 6kV and 10kV.
The basic installation type of this series motor is horizontal with foot (IMB3) structure.
The Y/YR series is the basic series of motors, and the YKS/YRKS/YKK/YRKK series is a series of products derived from the different cooling methods and protection levels of the motors. Among them, YKS/YRKS is an air-water cooling method, and YKK/YRKK is an air-air cooling method.
This series of motors comply with the relevant standards of the International Electrotechnical Commission IEC, in line with the provisions of GB755 "rotary motor quota and performance. Y basic series in line with JB/T7593-1994 "Y series high voltage three-phase asynchronous motor technical conditions". YR basic series conforms to JB/T7594-1994 YR series high voltage three-phase asynchronous motor technical conditions
Seat
The frame of this series motor adopts box structure, which is formed by welding steel plate, with light weight and good rigidity. There are windows on both sides and the top to facilitate the maintenance of the motor. At the same time, different coolers are installed on the top to derive motors with different cooling methods and protection levels.
Stator
The stator adopts external press-fit structure, and the stator winding adopts Class F insulation material, and reliable anti-corona measures are taken. The stator slot of this series of motors is embedded with winding temperature measurement PT100 for reliable monitoring of motor temperature rise. The embedded stator winding is treated by vacuum pressure impregnation (VPI) and rotary baking insulation process. The motor has good insulation performance, high mechanical strength and long service life.
Rotor
The rotor has two structures of cage and winding, both of which are manufactured by advanced and reliable technology, and after dynamic balance check, the motor runs smoothly and reliably.
Bearing
The bearing adopts two forms of rolling bearing and sliding bearing. The rolling bearing is equipped with non-stop oil injection and drainage device. The sliding bearing generally adopts self-lubricating method or forced lubrication according to user requirements. The degree of protection of the bearings is IP54. This series of motors are equipped with a small PT100 screw-in resistance thermometer on the bearing for reliable monitoring.
Junction box
The protection level of the motor junction box is IP54. The structural design of the junction box meets the explosion-proof requirements. The main junction box is placed on the right side of the motor (viewed from the shaft extension end) or on the left side according to user requirements. Separate grounding terminals are provided inside and outside the junction box to ensure reliable grounding.
