Golden Motor 10kW Liquid-Cooled BLDC Electric Motor (48V-120V)

The liquid-cooled HPM10KW gives you 10kW class power that can keep running hard: up to 20kW rated output at higher voltages, 91% efficiency, and water cooling that holds temperatures down through long, heavy-load runs. It's the pick for electric boats, heavy utility vehicles, enclosed motor bays and any build that spends a lot of time near full power.

Why Choose Liquid Cooling

• Sustained power. Liquid cooling pulls heat out of the motor far better than air, so it can hold high output longer without hitting thermal limits.
• Great for boats and enclosed spaces. Ideal where there's little airflow, like an engine bay or a hull.
• Easy plumbing. NPT 1/4-18 water ports, 12 mm hose, and swappable water fittings.
• Four voltage options. 48V, 72V, 96V or 120V, with rated power rising from about 8kW to 20kW as voltage goes up.
• CE certified. Independently EMC tested by EMTEK (Shenzhen), an ISO/IEC 17025 accredited lab.

Choosing a Controller

Pick your controller by the power you'll use continuously and match it to your battery voltage:

• 72V: EZkontrol 72V in the B72800 size (7–12 kW) or B721000 (9–14 kW)
• 48V: EZkontrol 48V in the B481000 size (6–10 kW) or larger
• 96V / 120V: EZkontrol 96V or EZkontrol 120V

EZkontrol includes HPM factory presets, so no self-learning is needed. Keep the controller's max bus current at or below your battery BMS's continuous rating. Don't need liquid cooling? The air-cooled HPM10KW skips the plumbing.
