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

The HPM10KW is a 10kW class BLDC motor for serious power: up to 20kW rated output at higher voltages, 91% efficiency and a 17 kg air-cooled body that runs on 48V, 72V, 96V or 120V. It's built for electric motorcycle conversions, performance go-karts, utility vehicles, boats and industrial machines.

Why Builders Choose the HPM10KW

• Big power, simple cooling. Air cooled, so there's no pump, radiator or hoses to add to your build.
• Four voltage options. 48V, 72V, 96V or 120V, with rated power rising from about 8kW to 20kW as voltage goes up.
• Efficient. Up to 91% efficiency for more range per charge.
• Proven with EZkontrol. Our 72V test curve below was run on an EZkontrol B72800, and EZkontrol includes HPM factory presets so no self-learning is needed.
• CE certified. Independently EMC tested and certified (details below).

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

Oversizing the controller is safe, since the motor only draws the current it needs. Keep the controller's max bus current at or below your battery BMS's continuous rating. Running long full-power duty cycles or in a hot, enclosed space? Consider the liquid-cooled HPM10KW.

• Radiated emissions (30 MHz – 1 GHz, tested at 72V DC): passed
• Electrostatic discharge (±8 kV air / ±4 kV contact): passed, Criterion B
• RF field immunity (80 MHz – 6 GHz, 10 V/m): passed, Criterion A
• Magnetic field immunity (30 A/m, Level 4): passed, Criterion A
