Description
The BL370-F is a compact high-speed brushless DC motor designed for applications requiring high rotational speed, compact dimensions, and direct DC power connection.
The motor integrates its brushless driver electronics, eliminating the need for a separate external ESC or brushless motor driver. At 11.1V, the motor reaches a no-load speed of up to 44,000 RPM.
Built with N50UH neodymium magnets and a compact 43.6 × 24 × 19.7 mm body, the BL370-F is suitable for compact robotic mechanisms, high-speed rotating equipment, experimental devices, and custom automation projects.
A 2 mm D-shaped output shaft provides secure mechanical coupling, while the 75 mm 20AWG power leads simplify electrical integration.

FAQ
Does this motor require an external brushless motor driver?
No. The BL370-F has a built-in brushless driver.
What is the no-load speed at 11.1V?
The specified no-load speed is 44,000 RPM.
What type of output shaft does it use?
It uses a 2 mm diameter D-shaped shaft with a 9.5 mm output length.
What is the motor weight?
Approximately 52g.
Can the motor be operated continuously at the stall condition?
No. Stall specifications represent a boundary operating condition and should not be treated as a continuous operating point.
