MT-3000-2S

MT-3000-2S aircraft electric motor

MT-3000-2S is a specialized aircraft electric motor used to convert electrical energy into mechanical rotation for onboard auxiliary equipment. In the supplied context, the motor is associated mainly with high-speed drive units and aviation centrifugal pumps. The unit may be classified as aviation technical property and is historically linked with production by the Dnepropetrovsk Aggregate Plant. MT-3000-2S is used where a compact aircraft motor with high shaft speed and continuous operating capability is required.

Function of MT-3000-2S in aircraft systems

The main function of MT-3000-2S is to provide mechanical drive power for rotating aircraft units. The motor supplies torque to connected pump or auxiliary equipment assemblies and supports operation of onboard systems that require liquid transfer, pressure generation or circulation. In the source context, its primary associated unit is the ECN-17 electric centrifugal pump. Correct motor operation is important for stable pump performance and reliable function of the connected aircraft system.

Use with ECN-17 centrifugal pump

MT-3000-2S is described as a drive motor for the ECN-17 electric centrifugal pump. In this configuration, the motor drives the pump impeller and allows fuel or other working liquid to be transferred or circulated through the aircraft system. The source context describes ECN-17 as a pump used for liquid transfer and pressure generation. When supplied or replaced, compatibility should be checked by the pump assembly documentation, shaft interface, mounting dimensions and electrical connection data.

Series and related modifications

The “2S” index indicates the second series / modification of the MT-3000 motor family. Related versions mentioned in the supplied context include MT-3000-3S and the modernized MT-3000M / MT-3000M-2S. These variants may differ by dimensions, mechanical interface, electrical characteristics or installation requirements. They should not be treated as automatic substitutes without checking the technical documentation of the parent unit. For repair or procurement, the exact designation on the motor label and passport should be used.

Electrical and mechanical characteristics

According to the supplied data, MT-3000-2S operates from a 200 V, 400 Hz three-phase supply in the relevant aircraft / equipment configuration. The motor has a shaft speed of not less than 7600 rpm, current consumption up to 16 A and rated shaft torque of 36 kgf·cm. Its compact body and mass limit make it suitable for integration into aircraft pump units and high-speed assemblies. Exact connection diagrams and phase wiring should be confirmed by the product passport and equipment documentation.

Identification and ordering of MT-3000-2S

Before ordering MT-3000-2S, the buyer should confirm the parent unit, aircraft type, pump model, shaft configuration, mounting interface, condition and documentation requirements. It is especially important to state whether the motor is required specifically for ECN-17 or for another onboard drive unit. The item may be needed for pump repair, replacement of a defective motor, overhaul stock or support of aircraft liquid-transfer systems. Product passport, test records and preservation documents should be checked before shipment.
