This motor is a three-phase asynchronous motor of the dry type, specifically designed for reliable operation with submersible pumps. Cooling is achieved through water circulation along the external casing, ensuring stable performance under challenging conditions. The motor is designed for vertical installation, with a continuous duty rating (S1) that guarantees long-term reliability and high efficiency.
Basic parameters
1. The rated frequency of the motor is 50 Hz, and the rated voltage is 380 V, 660 V, 3 kV, 6 kV, 10 kV.
2. The relationship between the motor frame number, speed, and power should comply with the specifications in Tables 1 and 2.
