Basic Information

Product Overview

The AMI series modular induction motors are engineered to deliver exceptional reliability and availability in the most demanding industrial applications. Built upon a highly successful modular platform, these motors offer the flexibility to be tailored to specific customer needs while fully complying with international standards.

Key features include:

• Versatile Operation: Available for both direct-on-line (DOL) and variable speed drive (VSD) applications.
• Robust Construction: Features a durable welded steel frame with standard shaft heights ranging from 400 to 630 mm.
• Flexible Mounting: Designed for both horizontal and vertical installations.
• Wide Power Range: Output powers covered in this series reach up to 8,000 kW, with the complete platform extending up to 23,000 kW.
• Speed Range: Operates at both 50 Hz and 60 Hz, providing synchronous speeds from 500 to 3600 rpm.

Mounting Arrangements

Standard mounting configurations are designed to fit diverse installation environments. Custom arrangements 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 facing downwards).

Enclosure and Cooling Systems

The AMI motors offer multiple cooling and protection options to suit various environmental conditions:

• IC01 / IP24W (Weather Protected): Features a shaft-mounted cooling fan inside the housing. The air intake path is engineered with three acute direction changes (exceeding 90 degrees) and maintains an average velocity below 3 m/s. This design effectively settles heavier particles and protects against rain, snow, and splashing water from any direction.
• IC611 / IP55 (Air-to-Air Cooled): A fully enclosed design utilizing an air-to-air heat exchanger. Shaft-mounted fans are installed both inside and outside the casing to manage separate cooling circuits, providing complete protection against dust and splashing water.
• IC81W / IP55 (Air-to-Water Cooled): A fully enclosed motor equipped with an air-to-water heat exchanger. An internal shaft-mounted fan supplies the internal cooling circuit, ensuring optimal protection against dust and moisture.
• IC31 / IP55 (Remote Air Cooled): Fitted with inlet and outlet pipes for remote cooling air. This configuration essentially utilizes the AMI motor frame without an upper cover, maintaining IP55 protection against dust and splashing water.

Packaging and Transportation

To ensure safe transit, all motors are packed in standard seaworthy packaging suitable for long-distance transportation by sea or land. Options include sturdy plywood cases or wooden fumigation packages.
