Transfluid-Bellmarine Introduces the New DriveMaster 40W EVO: High-Performance Electric Propulsion at 48V

Combining permanent magnet technology, proven engineering and simplified integration, the new DriveMaster 40W EVO expands the possibilities of low-voltage marine propulsion.

Transfluid-Bellmarine announces the launch of the DriveMaster 40W EVO, a new permanent magnet electric motor delivering 40 kW at 1,500 rpm on a 48V platform.
Developed in response to the growing demand for powerful and efficient electric propulsion, the new motor offers boatbuilders and operators an alternative to higher-voltage solutions, combining substantial power output with the practical advantages of low-voltage technology.
Designed for both recreational and professional marine applications, the DriveMaster 40W EVO reflects Transfluid-Bellmarine’s commitment to developing reliable, versatile and accessible propulsion systems.
Advanced Engineering Built on a Proven Platform
One of the key strengths of the DriveMaster 40W EVO lies in its mechanical design, which shares the architecture of Transfluid-Bellmarine’s established EM300 high-voltage motor series.
This engineering approach allows the new motor to benefit from proven mechanical solutions and common components, ensuring production efficiency and economies of scale.
For customers, the advantages extend beyond manufacturing. Standardised components improve spare parts availability, simplify maintenance and support long-term serviceability, an important consideration for commercial operators seeking to minimise vessel downtime.
The permanent magnet motor delivers high efficiency, excellent power density and responsive torque characteristics. Particular attention has also been given to thermal management and cooling, essential aspects of maintaining reliable performance at this power level within a low-voltage system.
Simplifying Electric Propulsion
By operating at 48V, the DriveMaster 40W EVO offers a practical alternative for applications where high-voltage installations may introduce unnecessary complexity.
Its electrical architecture can simplify system integration, installation and maintenance procedures, while reducing certain requirements associated with high-voltage equipment. In some European countries, this can also mean fewer specialist certification requirements for technicians and boatyards, subject to local regulations.
The motor provides smooth acceleration, precise manoeuvring and quiet operation, contributing to a more comfortable onboard experience.
Versatility Across Marine Applications
The DriveMaster 40W EVO is suitable for a wide range of vessels and operating environments.
For passenger boats and inland waterway transport, electric propulsion provides quiet navigation and zero local exhaust emissions, particularly valuable in urban waterways, lakes and environmentally sensitive areas.
Workboats, harbour service vessels and utility craft benefit from responsive low-speed control and reduced routine maintenance, while leisure boats, sailing catamarans and displacement yachts gain a comfortable propulsion solution with minimal noise and vibration.
A Long-Term Approach to Sustainable Propulsion
Beyond operational efficiency, the DriveMaster 40W EVO has been developed with long-term product value in mind.
Its shared mechanical platform encourages component standardisation and supports maintenance and repair over the motor’s lifetime. Combined with the reduced routine servicing requirements of electric propulsion, this approach helps optimise resource use and limit unnecessary component replacement.
With the introduction of the DriveMaster 40W EVO, Transfluid-Bellmarine continues to expand its electric propulsion portfolio, bringing together advanced motor technology, established engineering expertise and practical solutions for the evolving needs of the marine industry.
