4123 BLDC 41mm 24V Water Pump Brushless DC Motor 6 Slot High Torque Custom Drive Board OEM
4123 BLDC 41mm 24V Water Pump Motor with Drive Board
6 slot 41mm stator with integrated PWM driver, matched phase resistance and a polar difference held within 0.01 Ohm for low vibration pump duty.
Why buyers choose this motor
Torque headroom without a bigger frame
The 6 slot stator and matched magnet layout give the torque reserve needed to start against pump head pressure, while resistance stays in the 1.08-1.12 Ohm window.
Drive board inside the motor
Integrated PWM brushless driver removes the external controller, shortens phase leads and cuts EMI. Speed input and protection thresholds are set per project.
Low vibration for pump duty
Polar difference is held at or below 0.01 Ohm and inductance is controlled to 980 +/- 30 uH, keeping current balance tight and vibration low at running speed.
Technical specifications
All values are typical for the standard build. Winding, shaft and driver can be re-tuned to your target torque, speed or duty cycle.
Customization options built into the tooling
- Drive board firmware set for your speed curve, soft start and protection thresholds
- Pump flange, mounting holes and pilot diameter machined to your drawing
- Shaft length, D-cut and impeller fit produced per sample
- Winding turns and wire diameter tuned for flow and head pressure targets
- Voltage variants across the 12V-48V range using the same 41mm platform
- Connector, lead length and sealing options for wet or damp enclosures
Typical applications
Automotive auxiliary water pumps, circulation pumps, boiler and HVAC pumps, garden and pressure boosters, coffee machine pumps and industrial dosing systems.
Quality control and documentation
- Phase resistance and inductance matched per unit, polar difference logged
- Drive board function test with load emulation before assembly
- Hi-pot, insulation resistance and running current check on 100% of units
- Vibration and noise sampling per lot
- ISO 9001 control with RoHS and REACH declarations on request
