Product Description: Modular Induction Motors, Type AMI

High Reliability and Availability
AMI engineered modular induction motors are designed to provide exceptional reliability and availability, even in the toughest and most demanding industrial applications. Built on the motor industry's most successful modular platform, these tailor-made motors offer the flexibility to be adapted to highly specific configurations while meeting a broad variety of rigorous application requirements.

AMI modular induction motors comply with all relevant international standards and are available for both direct-on-line (DOL) and variable speed drive (VSD) operation. Featuring a robust welded steel frame, standard shaft heights range from 400 to 630 mm, and they can be mounted horizontally or vertically. While technical data in this catalog is typically referenced at 50 Hz, these motors operate seamlessly at both 50 Hz and 60 Hz, with synchronous speeds ranging from 500 to 3600 rpm. Output powers covered in this catalog reach up to 8,000 kW, with the complete range extending up to 23,000 kW.

Mounting Arrangements

Standard mounting arrangements for AMI motors include:

• IM B3 (Code II: IM 1001): Horizontal foot-mounted.
• IM V1 (Code II: IM 4011): Vertical flange-mounted (free shaft end facing downwards).
• Note: Other mounting arrangements are available upon request.

Enclosure and Cooling Systems

AMI motors are available with multiple standard cooling methods and protection types to suit diverse environments:

• IC01 / IP24 (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 an average velocity not exceeding 3 m/s. This design allows heavier airborne particles to settle, effectively reducing the ingress of rain, snow, and dust, while protecting against splashing water from any direction.
• IC611 / IP55 (Air-to-Air Heat Exchanger): A fully enclosed design utilizing an air-to-air heat exchanger. Shaft-mounted fans are fitted on both the inside and outside of the casing to supply independent cooling circuits, providing complete protection against dust and splashing water.
• IC81W / IP55 (Air-to-Water Heat Exchanger): A fully enclosed motor equipped with an air-to-water heat exchanger. An internal shaft-mounted fan supplies the internal cooling circuit, ensuring robust protection against dust and splashing water.
• IC31 / IP55 (Remote Cooling Air): Fitted with inlet and outlet pipes to utilize remote cooling air. This version essentially consists of the AMI motor frame without an upper cover, maintaining full protection against dust and splashing water.

Packaging

All motors are shipped in standard seaworthy packaging suitable for long-distance transportation by sea or land. Options include plywood packages or wooden fumigation packages to ensure safe transit.

Warranty Period

• Standard Warranty: 12 months after commissioning, or 18 months after delivery, whichever comes first.
• Extended Warranty: Warranty period extensions are available. Please contact us for more details.
