BL-2838 Sensorless DC Brushless Motor 12V 24V, U V W 3-Wire,

BL-2838 sensorless brushless DC motor 12V 24V 3000-10000 RPM

U V W 3-wire no hall brushless motor without driver

10.5mm 15mm shaft micro BLDC motor for CNC RC

Product Description

BL-2838 sensorless DC brushless motor, comes with only 3 phase wires (U, V, W), no hall sensor, driver is NOT included. Supports forward/reverse rotation and speed adjustment with external driver. Dual voltage options:12V / 24V.

Optional no-load speeds:3000,4000,5000,6000,7000,8000,9000,10000,12000 RPM.

Output shaft length optional:10.5mm,15mm.

Spec: BL-2838 Sensorless DC Brushless Motor; Voltage: 12V/24V; Speed: 3000/4000/5000/6000/7000/8000/9000/10000 RPM; Wire: U V W 3-Wire; Shaft: 10.5mm/15mm; No Hall Sensor, Without Driver.
Feature: Ultra-compact 28mm sensorless brushless design for high-speed direct drive (up to 10k RPM); U/V/W 3-wire output requires external ESC/driver; lighter & cost-effective vs Hall models; pairs with external PWM/ESC & full HH/MK/JQX/LC1D control stack.
Use: Mini CNC spindles, drones/RC, cooling fans, smart agriculture ventilation, robotic direct-drive, tachometer-tested speed loops.
Pairing: Drive via external ESC/PWM (DM556/YMS7-B not native, use BLDC ESC); power by 3-60V/3-90V PSU; logic via HH52P/MK2P → JQX-38F/LC1D for main power; wire UL2464 (power) & UL2547 (signal); test 4mm banana; coupler GX/M12; read XD tachometer; clean with cordless washer.
Note: Sensorless = no Hall feedback (vs BL-3657); needs proper ESC for startup; 24V for higher speed/torque; 10.5/15mm shaft; ideal lightweight high-RPM micro-drive bridging GP reducers & heavy AC gear.
