全国服务热线Structure and characteristics of YLKK high-voltage vertical three-phase asynchronous motor
YLKK series motors adopt the internationally popular box-type structure with high process performance. After removing the protective cover (or cooler), you can observe and touch the inside of the motor, which is convenient for installation and maintenance of the motor. The junction box has a compact structure and a high protection level. While the connection of the terminal is reliable, the wiring method is flexible and can be connected in multiple directions.
The rotor of the motor is generally made of cast aluminum rotor, without the phenomenon of broken copper bar rotor, and the operation is reliable; the stator adopts an external press-fit structure, F-class insulation material and anti-corona material and vacuum impregnation treatment, so that the motor has excellent and reliable insulation performance and moisture-proof and anti-corrosion. impact capability.
The bearing selection is based on the axial thrust of the motor. Generally, the upper bearing adopts two sets of rolling bearings, one of which is a thrust bearing, and the lower bearing structure is a rolling bearing. The motor with rolling bearing structure has non-stop refueling and oil discharge devices, which improves the operating efficiency of the motor.
YLKK high-voltage vertical three-phase asynchronous motor operating conditions and working methods
The altitude does not exceed 1000m;
The maximum ambient air temperature range does not exceed 40°C, the minimum ambient air temperature for rolling bearing motors is not lower than -15°C, and for sliding bearing motors is not lower than 5°C;
When the motor is running, the motor operating voltage deviation is allowed to be ±5%
Rated frequency is 50Hz, allowable power frequency deviation ±1%
For YLKS series motors, the temperature of the cooling water at the cooling inlet should not exceed 33°C, and the minimum is 5°C
