Submersible low-speed motor EDSS (System-Service electric motor) for operation of progressive cavity pumps
Purpose
Designed for long-term 50 Hz AC line operation, as well as work with control stations with frequency converters in the range from 20 Hz to 80 Hz as a motor for submersible progressive cavity pumps for pumping reservoir fluid from oil wells.Application
Used as part of an oil production unit and is a pump motor. The greatest effect is achieved when used aspart of installations:
• In low-rate and medium-rate well production;
• In complicated wells with high-viscosity oil and water-oil emulsion, contamination, etc.
• In wells with limitations for rod pumps due to well curvature and landing depth;
• In wells with no possibility of arranging the foundation for the sucker-rod pumping unit.
Work principle
In the stator winding, when it is connected to a three-phase current, a rotating magnetic field arises, which crosses the rotor rods and induces an electromotive force in them. Since the rotor rods are closed, a current will appear in them under the action of this force. This current, interacting with the magnetic field, creates a torque, under the influence of which the rotor will begin to rotate. The direction of rotation will coincide with the direction of rotation of the stator field, however, in terms of rotation speed, the rotor will slightly lag behind the stator field, therefore these motors are called asynchronous. Thus, the electrical energy supplied to the stator winding from the network is converted into mechanical energy of rotation of the motor shaft.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.
Purpose
• Optimum frequency – from 50 to 480 rpm;• Use of a standard control station for asynchronous motors;
• High adaptability of the installation to the well flow rate (accuracy in up to 0.43 rpm increments);
• Possibility of using progressive cavity pumps designed for top drive.
