Product Description
AMI series modular three‑phase induction motors deliver outstanding reliability for heavy‑duty industrial working conditions. Built on proven modular platform, these squirrel‑cage motors can be customised to satisfy diverse customer‑specific operating requirements.
The motors conform to global applicable standards, supporting both direct‑on‑line (DOL) startup and variable speed drive (VSD) operation. Adopting welded steel housing structure, AMI motors provide multiple cooling and protection combinations: IC01/IP24W, IC611/IP55, IC81W/IP55. Frame height ranges from 400 mm to 630 mm, supporting horizontal foot‑mounted and vertical flange‑mounted installation.
Though catalogue technical data is displayed under 50Hz condition, the motors run stably at 50Hz and 60Hz, with synchronous speed covering 500‑3600 rpm. Catalog‑covered power reaches 8000 kW while full product range can hit 23000 kW. The AMI 400L8A model featured here is a 280kW‑530kW, 6000V, 8‑pole motor widely used for cement plant mill equipment.
Mounting Arrangements
Standard configurations include IM B3 (IM1001, horizontal foot‑mounted) and IM V1 (IM4011, vertical flange‑mounted with shaft end downward). Special mounting forms are available upon request.
Enclosure & Cooling Options
IC01 / IP24
Weather‑protected design equipped with shaft‑driven internal cooling fan. Optimized air intake path restricts air velocity below 3 m/s with multiple sharp direction turns, stopping rain, snow and airborne debris from entering internal components. Offers full‑direction splash‑water resistance.
IC611 / IP55
Fully enclosed structure fitted with external air‑to‑air heat exchanger. Shaft‑driven internal and external fans serve separate inner‑outer cooling loops. Resists dust ingress and omnidirectional splashing water.
IC81W / IP55
Totally enclosed motor equipped with air‑to‑water heat exchanger. Internal shaft fan maintains inner circulation circuit. Reliable dust‑proof and splash‑proof performance.
IC31 / IP55
Designed with dedicated inlet and outlet pipelines for remote cold air supply, adopting motor main frame without top cover. Provides dust and splash water protection from all directions.
IC01
Variant with asymmetric internal air circulation layout.
Packaging
Export‑oriented seaworthy packing includes plywood case or fumigated wooden case, suitable for long‑haul sea and land logistics.
Warranty
Standard warranty is 12‑month upon commissioning or 18‑month after goods delivery, whichever occurs earlier. Extended warranty service is negotiable, please get in touch for further information.
