AMI 630L8AB High Voltage a c Electric Induction Motor 3150kW,4200kW,750RPM,3000V 50Hz IP55 IC611 Cooling

The AMI series are high‑performance modular induction motors built for outstanding reliability and uptime under harsh, demanding industrial operating conditions.

Custom‑engineered to satisfy individual customer and application requirements, these motors are developed on a proven mature modular platform. They can fulfill diverse heavy‑duty operating needs and support highly customized configurations.

AMI modular induction motors conform to relevant international standards. They support both direct‑on‑line (DOL) and variable speed drive (VSD) operation modes.

Constructed with welded steel frames, the motors offer standard combinations of cooling systems and protection classes: IC01 / IP24W, IC611 / IP55 and IC81W / IP55. Standard frame sizes cover 400 mm to 630 mm, with horizontal and vertical mounting options available.

This catalogue lists technical data under 50 Hz condition only. Nevertheless, AMI motors run at both 50 Hz and 60 Hz, delivering synchronous speeds ranging from 500 rpm to 3600 rpm. The power range shown in this catalogue reaches up to 8 000 kW, while the full product portfolio extends to 23 000 kW.

IM B3 (IM 1001): Horizontal foot‑mounted (standard) IM V1 (IM 4011): Vertical flange‑mounted, free shaft end pointing downwards

Other mounting forms can be supplied upon special request.

Weather‑protected design fitted with a shaft‑driven internal cooling fan. The air intake path limits average airflow velocity below 3 m/s to allow heavy particles to settle, with three sharp turns over 90° to optimize airflow. This structure minimizes ingress of rain, snow and airborne contaminants into internal electrical components and provides protection against splashing water from all directions.

Fully‑enclosed unit equipped with an on‑board air‑to‑air heat exchanger. Shaft‑mounted fans are installed inside and outside the motor casing to drive internal and external cooling circuits separately. Provides full‑range protection against dust and splashing water.

Fully‑enclosed high‑voltage motor equipped with air‑to‑water heat exchanger. One shaft‑driven internal fan circulates air for the inner cooling loop. Rated IP55 for dust and splash‑water resistance.

Designed with dedicated inlet and outlet pipe interfaces for remote cooling air supply. The top cover is removed for this version. IP55 protection against dust and splashing water from all directions.

Features asymmetric internal air circulation for effective internal heat dissipation.

Export‑grade standard seaworthy packaging is adopted. Options include plywood case or fumigated wooden package. Packages are well‑suited for long‑distance sea and land transportation.

Standard warranty: 12 months after commissioning or 18 months after delivery, whichever occurs earlier. Extended warranty service is available. Please contact our sales team for further information.
