Description
Submersible Motor is a robust, high-performance motor designed to drive submersible centrifugal pumps for pumping underground crude oil. This advanced system utilizes a diode three-phase squirrel-cage asynchronous motor, making it suitable for complex applications. The motor features a vertical suspension structure composed of a stator, rotor, bearings, couplings, and ancillary components, ensuring efficient operation. With a length range of 1.5 to 10 meters and the ability to connect multiple motors in series, it can adapt to various well casing sizes, including 4½”, 5½”, 7″, and 8⅝”.
The submersible motor operates effectively within a voltage range of 200V to 3500V and a current of 10 to 120A, with power proportional to length. Operating at a speed of 2850-2900 r/min at 50Hz, this motor is designed for durability and efficiency, featuring refined mineral oil for insulation, lubrication, and cooling.
Additionally, it offers two types of insulation treatment: dipping paint and epoxy, with temperature grades suitable for environments up to 180ºC. For specific applications exceeding 150ºC, custom specifications are available. The motor’s design also includes a self-starting capability and can accommodate special requirements for heat dissipation, ensuring optimal performance in various conditions.

Additional Information
The submersible motor is designed to operate efficiently in conditions where the surface flow rate is not less than 0.3 m/s. Should the surface flow velocity be lower than this threshold, the motor selection should be adjusted accordingly. In specialized applications, a heat radiating device may be required to enhance the motor’s heat dissipation capability.
