12174 BLDC 12 Slot 5V Brushless DC Motor 22.5mm 820 RPM Low Cogging for Drone Gimbal
12174 12 Slot Brushless Motor 5V 820RPM
22.5mm stator, 12 slots, 5V DC. Designed for drone gimbals and precision heads that need a smooth, low-cogging rotation at very low current.
12 Slots5V DC820 RPM24 mALow CoggingDesign Focus: 12 Slots Spread the Cogging
Cogging in a small brushless motor is a geometric problem. With 12 stator slots the detent torque is distributed over more positions per revolution, so each step is smaller: a gimbal axis driven by this stator moves through its travel without the visible notch that a 6-slot stator produces. The same geometry keeps the audible noise low at 820 RPM, which matters when the motor sits centimetres from a microphone.
Winding control is the other half of the story. Resistance is held inside 38.13 - 43.87 Ohm with the polar difference under 1.0 Ohm, so all three phases pull almost the same current and the drive does not have to fight an imbalance. Inductance of 8.84 - 10.16 mH suits a PWM driver running in the 20-30 kHz band.
