Brushless motor RB-29-62 series

BLDC100 V12 V

Product overview
The RB-29-62 is a 29 mm class brushless DC motor (BLDC) engineered for high-speed air-moving applications. Typical capabilities include nominal speeds around 110,000 rpm (variants up to 120,000 rpm), a compact 28.8–29 mm effective diameter and an 11‑blade aluminum alloy impeller optimized for airflow and pressure. Available in configurable voltage ranges with deep OEM/ODM customization options.

Customization and sourcing notes
OEM/ODM customization is supported across electrical and mechanical domains: voltage and speed ranges, required torque, shaft length and profile, impeller design and assembly, mounting hole patterns, cable/connector options, gearbox integration, and optional pre-installed driver board (PCBA) or housing. Final pricing and lead times depend on specified requirements, quantities and customization scope.

Core applications & solutions

• Professional salon-grade hairdryers (100 V / 220 V variants): high-power direct-drive versions with 11-blade impeller for strong instantaneous airflow.
• Industrial cooling & high-power portable fans (12 V variants): low-voltage options (up to 150 W) for powerful cooling of equipment and battery-powered fans.

Technical specifications (examples)
*Data source: KWC RB-29-62 specification sheet.
RB-29-62-N-01 — Operating range 90–120 V — Nominal 100 V — Rated speed 110000 ±5000 rpm — Current ~2 A — Output 100 W
RB-29-62-N-02 — Operating range 180–260 V — Nominal 220 V — Rated speed 110000 ±5000 rpm — Current ~1.5 A — Output 100 W
RB-29-62-N-03 — Operating range 9–16 V — Nominal 12 V — Rated speed 120000 ±5000 rpm — Current ~12 A — Output 150 W

Comparison highlights
The RB-29-62 offers a larger effective diameter (~28.8 mm) and an 11‑blade impeller, delivering higher airflow and pressure versus typical 25 mm high-speed motors; maximum power reaches 150 W on selected variants compared with commonly <120 W on smaller motors.

Characteristics / additional notes
