Submersible AC electric motors
Hit
RINPO LLC, a subsidiary of Sistema-Service Group of Companies, produces submersible AC electric motors.
Details
Submersible AC electric motors
Purpose
Submersible AC electric motors with a size of 4.61 in are used as a motor for cavity pumps at a rotation speed of up to 1500 rpm and centrifugal pumps at a rotation speed of up to 4200 rpm. Rotation speed control ranges from 500 to 4200 rpm.AC electric motors represent a new generation of energy-efficient equipment. They are produced in three-phase, oil-filled, and single-section versions. The poles on the rotor are formed by permanent magnets made from alloys of rare earth elements.
Application
Used as part of an oil production unit and is a pump drive.Work principle
The work principle of an AC motor is based on a clear positioning of permanent magnets on the rotor in relation to the formed peak of the electromagnetic pulse on phase electrical windings. When the magnets move, the sensors receive information about their position and change the capacity of the reactive valve converters, which allows the shaft to rotate further.Package contents

At customer’s request, motors can be equipped with a telemetry system for submersible electric motors, which allows you to obtain real-time data on the operation and the well conditions in the motor mounting area and to promptly shut down the unit in case of overstress. Transmission of signals from the submersible unit of the telemetry system to the control station is carried out via a power cable of the electric motor.
Advantages
AC electric motors, compared to asynchronous motors:• High efficiency and power factor,
• Overall length and weight less by 40% with the same power,
• Reduced heat generation,
• Because of reduced current – less power loss in the cable line, control unit, and three-phase transformer,
• Because of shorter length, the centrifugal electric pump can be operated in highly deviated and horizontal wells,
• Adjustable RPM range at constant torque,
• Significantly increased power in the singlesection version,
• Reduced power consumption.
