Specifications:

All motors are Permanent Magnet AC with high efficiency and IP65 rating.
Intermittent power is defined as S3 10% - 10’ (1 minute at intermittent power, then reduced for 9 minutes).
Motors are available with air or liquid cooling, suitable for different duty cycles (Light, Medium, Heavy).
Battery voltage ranges from 48V to 144V, with specific minimum and maximum values provided for each range.

Components Included:

Motor with mounting brackets and silent blocks.
Integrated thrust bearing (up to 20kW).
Vector control inverter IP65.
Built-in DC-DC converter 12 Vdc for internal use.
Precharge circuit and 5m cable for display, lever, and key.
Key panel with OFF-ON-ECO modes.

Optional Components:

Main switch and fuse for specific battery configurations.
Drop box DP280 with various gear ratios.
Regeneration kit for energy recovery.

Performance Ratings:

Cruising speed is 70% of rated motor rpm.
Light Duty: Air-cooled, up to 200 hours/year, intermittent kW allowed.
Medium Duty: Air-cooled, up to 500 hours/year, nominal kW allowed; Liquid-cooled, up to 1000 hours/year, intermittent kW allowed.
Heavy Duty: Liquid-cooled, up to 3000 hours/year, intermittent kW allowed, max 80% of time at rated rpm and load.

Additional Notes:

Motors are designed for installation on shaft lines, offering maximum efficiency and compactness.
Regeneration via dragged propeller is possible.
Selection of display and control lever is necessary to complete the propulsion system.
