H-Series

Redefining the Electric Inboard Experience
Popular with sailboats and small watercrafts

H-Series Inboard Motors 60-250kW

Highly-integrated Modular Design OEM Capability

The H-Series is our 60-250 kW inboard range, engineered for larger sailing boats and motor vessels between 60 and 100’ (18-30m) with a full displacement up to 200 tons. They can deliver high performance with less noise, fewer vibrations and zero exhaust fumes.

H-100 Electric Motor 100kW

The H-100 is approximately two-thirds lighter and 50% more compact than its diesel equivalent, offering enhanced installation versatility and optimising both payload and passenger space. Its flat wire motor design improves slot fill by 25%, thereby boosting power density.

Modular Design

The H-Series motors features a modular design, providing manufacturers with the flexibility to easily extend both range and power by adding additional motors, controllers, and batteries. This adaptability allows for various power combinations to be selected based on specific needs, making the motors highly expandable.

Boating IoT System: Smart and Customisable

Our boating Internet of Things (IoT) system offers customisable solutions tailored to your needs for remote monitoring and integrated management. Features such as speed, power, tracking, mileage, and safety alerts can be adapted to meet your specific requirements. Boat owners can utilise the web portal for real-time tracking and comprehensive management of their vessels.

Optimum Performance, Pioneering Technology

Armed with pioneering permanent magnet motor technology, the H-100 sets a new standard, outperforming its diesel equivalents. With a maximum torque of 2000 Nm and an impressive 96% efficiency, it surpasses the capabilities of traditional 100 kW AC asynchronous motors.
