Submersible asynchronous electric motors of unified

Asynchronous two-pole submersible oil-filled motors with squirrel cage rotor PED series in 117 mm size, climatic version B, placement category 5 according to GOST 15150-69 and GOST 15543-70, designed for continuous operation mode S1 according to GOST IEC 60034-1-2014 from AC network with frequency 50 Hz. When using a frequency regulator, the motors can operate at AC frequency from 35 to 70 Hz with recalculation of the supply voltage for each value of the mains frequency. The rated current remains unchanged when the mains frequency and voltage values change proportionally, i.e.

it must not exceed the rated current value for the particular motor. The motors are used as a drive for submersible centrifugal pumps of ECNA type TU 3631-025-21945400-97 for pumping formation fluid from wells with an angle of deviation from the vertical not exceeding 60°, and submersible centrifugal pumps of ECNAV type TU 3631-081-48687408-2005 for water injection into the formation (installations for...).
