IC01 / IP24W: Weather-protected design with an internal shaft-mounted cooling fan. The air intake path incorporates three acute direction changes exceeding 90 degrees, maintaining an average velocity below 3 m/s to prevent ingress of rain, snow, and heavy airborne particles. Provides protection against splashing water from any direction.
IC611 / IP55: Fully enclosed motor equipped with an air-to-air heat exchanger. Shaft-mounted fans are installed both inside and outside the casing to supply internal and external cooling circuits independently. Provides protection against dust and splashing water from any direction.
IC81W / IP55: Fully enclosed motor fitted with an air-to-water heat exchanger. An internal shaft-mounted fan supplies the internal cooling circuit. Provides protection against dust and splashing water from any direction.
IC31 / IP55: Designed with inlet and outlet pipes for remote cooling air supply. This configuration utilizes the AMI motor frame without an upper cover. Provides protection against dust and splashing water from any direction.

Packaging: Standard seaworthy export packaging using plywood cases or fumigated wooden crates, suitable for long-distance sea and land transportation.
Warranty: Standard warranty period is 12 months after commissioning or 18 months after delivery, whichever occurs first. Extended warranty periods are available upon request.
