BLDC370 BLDC2430 Brushless DC Motor 5-26V Wide Voltage 24.4mm Low Cogging 20000h

WIDE VOLTAGE · LOW COGGING SERIES

BLDC370 / BLDC2430 5-26V Wide Voltage Low Cogging Brushless DC Motor

One 24.4 mm brushless motor platform that spans 5V to 26V DC and turns with noticeably low cogging torque - built for micro pumps, dosing systems and battery-powered appliances that need smooth low-speed rotation from a single motor family.

Wide Voltage Compatibility

The BLDC370 / BLDC2430 platform runs from 5V up to 26V DC on one mechanical envelope, so a single motor family covers 5V, 6V, 9V, 12V and 24V projects. Winding and driver firmware are matched to the rated voltage you specify, and speed stays stable when supply voltage drifts inside the working window.

• Voltage range 5-26V DC, five standard windings (BLDC370-1 to BLDC370-5)
• Speed regulation by PWM duty cycle, no re-winding needed for voltage changes
• Low-voltage start-up behaviour tested from 4.5V for battery-powered devices

Low Cogging Torque Design

A 2-pole permanent magnet rotor combined with an optimised stator slot profile keeps detent torque small and even, so the shaft turns smoothly at low speed instead of stepping between magnet positions.

• Reduced detent torque for smooth low-RPM rotation and quiet start-up
• Low torque ripple improves speed uniformity in pump and dosing applications
• Low EMC and low audible noise without extra shielding

Stator & Winding

Stator size Φ24.4 x L30.8 mm, shaft Φ2 mm with screw lead or D-cut, shaft length freely customised. Coils are wound in-house on automatic lines for prototype and mass-production batches.

• Rated output 2W-30W, rated torque up to 75 gf.cm
• Built-in driver PCB with MCU available as an option
• Insulation Class A, operational temperature -20°C to +80°C

Mechanical Structure & Life

All-metal brushless construction, permanent magnet rotor, electronic commutation by PWM drive, CW/CCW rotation. No carbon brushes to replace, so service life reaches up to 20,000 hours.

• Weight 25 g, compact 24.4 mm frame fits handheld and portable devices
• Designed for micro pumps, medical dosing units, air valves and personal care appliances
