4123 BLDC 41mm 24V Water Pump Brushless DC Motor 6 Slot Wide Voltage Low Cogging
WIDE VOLTAGE · LOW COGGING SERIES
4123 41mm 24V Wide Voltage Low Cogging Brushless DC Pump Motor
A 41 mm, 6-slot brushless pump motor with an integrated PWM drive board: wide voltage input keeps flow stable, low cogging torque keeps start-up smooth and quiet, and the brushless design reaches 20,000 hours.
Wide Voltage Water Pump Drive
The 4123 41 mm stator is supplied with an integrated PWM drive board that regulates the motor across a wide input window, so pump output stays constant while battery voltage falls or the supply fluctuates.
- 24V nominal, custom winding from 12V to 36V on request
- Integrated brushless drive board with PWM speed input
- Stable flow rate under voltage sag in battery-powered pump sets
Low Cogging Torque for Pumps
A 6-slot stator with matched magnet arc keeps detent torque low, so the impeller accelerates smoothly instead of jumping between cogging steps. The result is quieter priming, less vibration at low flow and longer seal life.
- Low cogging design reduces start-up vibration
- Even torque delivery for stable pressure in diaphragm and centrifugal pumps
- Low EMC and low noise for household and medical pump applications
Stator Electrical Data
Stator size Φ41 mm, 6 slots, phase resistance 1.08-1.12 ohm at 23-26 degrees C with polar difference under 0.01 ohm, inductance 980 +/- 30 uH. All values can be tuned for your pump curve.
- Phase resistance 1.08-1.12 ohm (23-26 C)
- Inductance 980 +/- 30 uH
