Product Description
1. Product Overview
AMI series are engineered modular induction motors featuring high reliability and operational stability, well‑suited for harsh and demanding working conditions.
Custom‑configurable to satisfy diverse customer and application requirements, these motors are built on a proven mature modular platform. They can fulfill a wide range of demanding operating scenarios and support highly‑specialized customized configurations.
AMI modular induction motors comply with relevant international standards. They support both direct‑on‑line (DOL) startup and variable‑speed drive (VSD) operation modes.
The motor adopts welded steel frame construction. Standard available combinations of cooling system and protection grade include IC01 / IP24W, IC611 / IP55 and IC81W / IP55, with standard shaft heights ranging from 400 mm to 630 mm. Both horizontal and vertical mounting types are optional.
The technical data shown in this catalogue is based on 50 Hz operation. Nevertheless, the motors can run under 50 Hz and 60 Hz power supply, delivering synchronous speeds from 500 rpm to 3600 rpm.
The power range covered in this catalogue reaches up to 8000 kW, while the full product portfolio extends to 23000 kW.
2. Mounting Arrangements
Below are standard mounting forms for AMI motors; other mounting types are available upon customer request.
- IM B3 (Code II: IM 1001): Horizontal foot‑mounted
- IM V1 (Code II: IM 4011): Vertical flange‑mounted, free shaft end pointing downwards
3. Enclosure & Cooling Modes
IC01 / IP24
This weather‑proof motor is equipped with a shaft‑driven internal cooling fan inside the housing. Its structural design minimizes ingress of rain, snow and airborne particles into electrical components.
The air intake is designed to keep average airflow velocity below 3 m/s for heavy particles to settle down. The air passage contains more than three sharp direction changes over 90°, further optimizing airflow rate. The motor provides protection against water splashes from all directions.
IC611 / IP55
Fully‑enclosed structure fitted with an on‑board air‑to‑air heat exchanger.
Shaft‑driven fans are installed inside and outside the housing to drive internal and external cooling circuits respectively. It offers protection against dust and omnidirectional splashing water.
IC81W / IP55
Fully‑enclosed motor equipped with air‑to‑water heat exchanger. An internal shaft‑driven fan circulates air for the inner cooling loop. It provides protection against dust and splashing water from all directions.
IC31 / IP55
Designed with dedicated air inlet and outlet pipes for remote cooling air supply. This variant is based on AMI motor frame without top cover. Dust‑proof and splash‑proof against water from any direction.
IC01
Adopts asymmetric internal air circulation design.
4. Packaging
Export‑grade standard seaworthy packaging.
Options include plywood case or fumigated wooden case.
Suitable for long‑distance sea and land transportation.
5. Warranty Terms
Standard warranty: 12 months upon commissioning or 18 months after delivery, whichever occurs earlier.
Extended warranty service is available. Please contact our sales team for further information.
