The NL0242 motor kit is the mechanical heart of NOVAL’s ATC sliding sunroof systems. Installed within the central rail, it drives the belt mechanism responsible for the precise and fluid movement of the roof panel.

Operating on a 24V DC power supply, the motor delivers a nominal current of approximately 5A, with peak start-up currents reaching up to 20A depending on installation conditions. This ensures sufficient torque to overcome environmental resistance such as wind pressure, salt buildup, or structural loads encountered at sea.

The motor is supplied ready for installation, complete with its drive output pulley and a fully assembled power cable featuring a dedicated marine-grade connector, ensuring seamless integration with the NOVAL control system.

Fully integrated into a complete system, the motor works in coordination with:

Control unit NL0129
Open position sensor NL0241
Closed position sensor NL0243

This synchronized system ensures:

Accurate and repeatable roof positioning
Protection against overtravel and mechanical stress
Extended lifespan of belts, rails, and moving components

The motor operates through a belt-driven transmission system, where correct tensioning and alignment are critical. Proper installation guarantees smooth motion, reduced wear, and consistent performance over time.

This motor is widely used across premium yacht brands equipped with NOVAL ATC sunroof systems, including Beneteau, Jeanneau, Prestige, Galeon, Sessa Marine, and Filippetti Yachts.
