10KW PMG Generator / Sail Drive

HPM-10KW PMG Generator – 48V High Output Permanent Magnet Generator with Alternator Mounting (Sail Drive Conversion Ready)

The HPM-10KW PMG Generator is a high-efficiency permanent magnet generator designed for 48V marine power systems, hydro-generation and electric sail drive conversions. Engineered with a compact aluminium housing and alternator-style mounting, this unit can be installed in place of a traditional alternator or driven via belt or direct coupling to provide powerful DC charging capability.

Operating as a permanent magnet generator (PMG), the HPM-10KW produces 3-phase AC output when mechanically driven, allowing efficient energy conversion for lithium house banks and high-capacity onboard electrical systems. When paired with an EZ Kontrol motor controller, the generator can also function as a propulsion motor, enabling hybrid installations and sail drive conversions from a single compact platform.

Key Features:
• Permanent magnet generator (PMG) designed for 48V systems
• Alternator-style mounting for engine-driven installations
• High output generation capability for large lithium battery banks
• Dual-purpose operation – generator or electric propulsion motor
• Compact aluminium casing with high thermal efficiency
• Compatible with air or liquid cooling configurations
• Ideal for hybrid marine charging and electric sail drive retrofits

Generator Performance:
The permanent magnet rotor delivers strong generating output proportional to shaft RPM, providing efficient power production across a wide speed range. With peak torque up to 80Nm and efficiency around 91%, the unit is suitable for continuous generation when properly regulated and cooled.

Hybrid Sail Drive Integration:
When coupled with an EZ Kontrol controller, the HPM-10KW can transition from a generator into a propulsion motor, enabling electric sail drive conversion or hybrid propulsion systems. This allows regeneration under sail and powered propulsion from the same unit, reducing system complexity while maximising onboard energy efficiency.

Ideal For:
48V lithium marine charging systems, hybrid propulsion retrofits, shaft-driven hydro-generation, engine-mounted PMG charging, electric sail drive conversions and advanced off-grid marine electrical installations.

The HPM-10KW PMG Generator provides a powerful and flexible solution for modern hybrid marine systems, combining high-output generation, alternator-style mounting and propulsion capability in a compact high-efficiency design.
