12174 BLDC 12 Slot 5V Brushless DC Motor 22.5mm 820 RPM Wide Voltage Low Cogging

WIDE VOLTAGE · LOW COGGING SERIES

12174 12 Slot 5V Wide Voltage Low Cogging Brushless DC Motor

A 22.5 mm 12-slot brushless stator with 820 RPM no-load speed and only 24 mA current draw - engineered for gimbal, drone and portable device drives that need a wide voltage window and smooth, low-cogging rotation.

Wide Voltage Operation

The 12174 12-slot stator is wound for 5V nominal use and accepts an extended working window through custom winding, so the same 22.5 mm stator serves 3.7V, 5V and 6V battery platforms without changing tooling.

• 5V nominal, custom winding for 3.7V-6V battery packs
• Flat no-load current of 24 mA or less keeps voltage sag low
• PWM wide-range speed control from a simple driver IC

Low Cogging Torque Winding

Twelve slots combined with a skewed magnet layout spread the detent torque into a smooth curve, so the rotor starts cleanly and rotates without visible stepping - the key requirement for gimbal, drone and optical stabilisation drives.

• Low cogging torque for smooth low-speed positioning
• Balanced 12-slot winding limits torque ripple under light loads
• Low EMC and low audible noise for indoor and camera applications
