2. Product Overview
The AMI series represents a modular induction motor platform engineered for reliability and uninterrupted availability in the most severe industrial environments. Each unit is custom-built around the customer's precise specification and application profile, drawing on one of the most proven modular platforms in the motor industry. This design balances broad adaptability across demanding operating requirements with the flexibility to accommodate highly specific configurations.
Fully compliant with all applicable international standards, the AMI range supports both direct-on-line (DOL) and variable speed drive (VSD) operation. The motors feature a robust welded steel frame, with standard cooling and protection combinations covering IC01 / IP24W, IC611 / IP55 and IC81W / IP55. Standard shaft heights span 400 to 630 mm, and the motors can be installed either horizontally or vertically. While the catalogue data is presented at 50 Hz, the AMI motors operate equally well at 50 Hz and 60 Hz, delivering synchronous speeds from 500 to 3,600 rpm. Power ratings covered here extend to 8,000 kW, with the full product family reaching up to 23,000 kW.
3. Mounting Arrangements
Standard mounting configurations for the AMI series are listed below; alternative arrangements are available on request.
| Code I | Code II | Configuration Description |
|---|
| IM B3 | IM 1001 | Horizontal foot-mounted |
| IM V1 | IM 4011 | Vertical flange-mounted (free shaft end facing downward) |
4. Enclosure and Cooling
IC01 / IP24 — Weather-protected motor with a shaft-mounted cooling fan integrated inside the housing. The internal design limits the ingress of rain, snow and airborne particles into the electrical components. Along the air intake path, the average velocity is kept below 3 m/s so that heavier particles settle out, and the path incorporates three acute directional changes exceeding 90° to further reduce airflow to the optimal level. The motor is protected against splashing water from any direction.
IC611 / IP55 — Fully enclosed construction fitted with an air-to-air heat exchanger mounted on the motor. Shaft-mounted fans are installed both inside and outside the casing to drive the internal and external cooling circuits respectively. The motor is protected against dust and splashing water from any direction.
IC81W / IP55 — Fully enclosed motor equipped with an air-to-water heat exchanger. A shaft-mounted fan inside the casing supplies the internal cooling circuit. The motor is protected against dust and splashing water from any direction.
IC31 / IP55 — Fitted with inlet and outlet pipes for connection to a remote cooling air supply. Essentially the AMI frame without an upper cover. The motor is protected against dust and splashing water from any direction.
Note: IC01 versions are also available with asymmetric internal air circulation.
5. Packaging
Export-grade seaworthy packaging, delivered in plywood or fumigated wooden crates, designed for reliable long-distance transport by sea or land.
6. Warranty
Standard warranty: 12 months from commissioning, or 18 months from delivery, whichever occurs first. Extended warranty terms are available on request — please contact us for details.
