Product Description

1. Product Overview

AMI Modular Induction Motors Deliver high reliability and outstanding availability for the harshest and most demanding industrial operating conditions.

Built on a proven modular platform, AMI modular induction motors can be custom‑engineered to satisfy individual customer and application requirements. They support a wide spectrum of demanding working scenarios, meanwhile offering high flexibility for highly‑specialized configuration adaptation.

These modular motors comply with relevant international standards, supporting both direct‑on‑line (DOL) and variable speed drive (VSD) operation modes.

AMI motors adopt welded steel frames. Standard available cooling & protection combinations include IC01 / IP24W, IC611 / IP55 and IC81W / IP55, with standard shaft height ranging from 400 mm to 630 mm. Both horizontal and vertical mounting options are supported.

Technical data shown in this catalogue is based on 50 Hz operation; nevertheless, the motors are compatible with 50 Hz / 60 Hz power supply, delivering synchronous speeds between 500 rpm and 3600 rpm. The catalogue covers output power up to 8,000 kW, while the full product portfolio can reach 23,000 kW.

2. Mounting Arrangements

Below are standard mounting forms for AMI motors. Other mounting types are available upon request.

• IM B3 (Code II: IM 1001): Horizontal foot‑mounted
• IM V1 (Code II: IM 4011): Vertical flange‑mounted (free shaft end pointing downward)

3. Enclosure & Cooling Options

IC01 / IP24

Weather‑protected design equipped with shaft‑driven internal cooling fan. The structural design minimizes ingress of rain, snow and airborne particles into electrical components. Air intake is designed to keep average airflow velocity below 3 m/s so that heavy particles can settle down. The air passage features three sharp turns over 90°, optimizing airflow rate. The motor resists water splashes from all directions.

IC611 / IP55

Totally‑enclosed structure fitted with an air‑to‑air heat exchanger. Shaft‑driven fans are installed inside and outside the enclosure to serve internal and external cooling circuits separately. Provides protection against dust and multi‑directional water splashes.

IC81W / IP55

Fully‑enclosed motor equipped with air‑to‑water heat exchanger. An internal shaft‑driven fan circulates air for the inner cooling loop. Dust‑proof and splash‑proof against water from all directions.

IC31 / IP55

Equipped with inlet and outlet pipes for remote cooling air supply. It is essentially the AMI motor frame without top cover. Protected against dust and omnidirectional water splashes.

IC01

Features asymmetric internal air circulation.

4. Packaging

Export‑grade standard seaworthy packaging, adopting plywood case or fumigated wooden case. Suitable for long‑distance sea and land transportation.

5. Warranty

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