YLBVF series motors are high-voltage cage rotor three-phase asynchronous motors. This series of motors are equipped with additional axial downthrust in accordance with IEC and NEMA technical conditions, and in accordance with UL, CE, CSA, Canada and SASO Saber certification in the United States. It can drive various types of vertical pumps, such as vertical mixed flow pumps, long-axis deep well pumps, axial flow pumps, mixing tanks and other equipment, and can be used for water conservancy facilities such as high-rise buildings, industry, agricultural drainage, farmland irrigation, etc.
The rating of YLBVF series motors is based on continuous working system (S1). The rated frequency is 0-100HZ (variable frequency operation), and the rated voltage is 220/380V, 380V, 3000V, 6000V, which can be designed into 3300V and 10000V according to the needs of users.
The enclosure protection grade of YLBVF series motors is IP23,IP54 IP55 TEFC;
YLBVF series motors can be rated for operation under the following environmental conditions:
1. The altitude shall not exceed 1000-2000 meters.
2. The lowest ambient temperature is -15 ℃, and the highest temperature changes with the seasons, but not more than 60 ℃.
3. The air is clean and there is no acid, alkali and other corrosive gases in the room. It is not allowed to work in an environment containing explosive gas or dust.
4. The monthly average maximum humidity in the wettest month is 90%, and the monthly average minimum temperature in that month is not higher than +25 ℃.
The guaranteed value of the ratio of the maximum torque to the rated torque of the YLBVF motor at the rated voltage is 1.6.
