39mm Brushless DC Motor 12V-24V | 3-Phase High-Speed Turbine Fan

Mini 39mm Inner Rotor Brushless DC Motor – High-Speed 3-Phase Turbine Fan

Upgrade your cooling or ventilation project with this compact 39mm inner rotor brushless DC motor. Operating on a wide voltage range of 12V to 24V, this 3-phase motor delivers impressive rotational speed with remarkably low operating noise — making it ideal for DIY builds, RC projects, electronics cooling, and custom turbine fan assemblies.

Key Features

• Neodymium Strong Magnetic Inner Rotor: High-efficiency neodymium magnets drive a powerful and consistent spin inside the 39mm brushless motor core.
• Front & Rear NMB Ball Bearings: Precision NMB ball bearings on both ends ensure smooth, stable rotation and long service life.
• Aluminum Alloy Shell with Heat Dissipation Slots: The robust aluminum alloy housing channels heat away efficiently, keeping operating temperatures in check even during extended use at 12V.
• Transparent Turbine Fan Shell: Well-crafted transparent fan housing provides both visual appeal and structural integrity for the turbine assembly.
• Quiet 3-Phase Operation: Runs significantly quieter than comparable high-speed fan motors, thanks to its brushless 3-phase design and precision-balanced components.
• Wide Voltage Range (12V–24V DC): Flexible input voltage suits a variety of power supplies and project configurations.
• CE Certified: Meets CE certification standards for quality and safety assurance.
• New & Individually Packaged: Each unit ships in protective bubble wrap packaging — new and unused.

Frequently Asked Questions

Q: Does this 39mm brushless motor come with a motor driver or ESC?

A: No, this turbine fan motor does not include a brushless motor driver (ESC). You will need to purchase a compatible 3-phase brushless motor controller separately to operate this motor.

Q: What voltage range does this brushless DC motor support?

A: This motor supports a DC input voltage of 12V to 24V. At 12V operation, the motor runs with minimal heat generation, making it well-suited for lower-power or space-constrained cooling applications.

Q: Is this motor suitable for DIY, RC, or electronics cooling projects?

A: Yes! The compact 39mm form factor, wide voltage range, quiet 3-phase brushless operation, and NMB ball bearing construction make this motor a great fit for DIY electronics cooling, RC vehicles, custom turbine fan builds, and maker board projects.

Q: How quiet is this brushless turbine fan motor compared to similar motors?

A: Thanks to its precision NMB ball bearings and optimized 3-phase brushless design, this motor operates considerably quieter than many comparable high-speed fan motors — ideal for noise-sensitive environments or desktop builds.
