FA-3264RD Two-Pole Coreless Brushless DC Motor
FA-3264RD is a high-performance 300W two-pole coreless brushless DC motor with 32mm outer diameter and an extended 64mm housing length. Reinforced double precision ball bearings deliver outstanding shock resistance and extended service life under heavy cyclic cutting loads. The two‑pole slotless rotor brings low rotor inertia, snappy dynamic response and zero cogging torque. A built‑in 3‑channel hall sensor offers reliable closed‑loop speed regulation. Four winding grades cover mainstream 24V, 36V, 40V and 48V industrial power supplies. Custom planetary gearboxes and EM22 incremental /absolute encoders are available for high-torque precision drive assemblies.

Engineering Overview
FA-3264RD two‑pole coreless BLDC eliminates cogging torque to achieve quiet, low-vibration rotation under heavy workloads. Upgraded heavy-duty ball bearings enhance anti-shock capability and service lifespan for long-duration high-load carving tasks. The extended rotor body delivers drastically higher continuous torque and stall torque, supporting demanding material cutting scenarios. Diverse speed-torque winding profiles accommodate lithium-powered heavy handheld tools and medium industrial automation hardware. A paired planetary gearbox multiplies output torque for rugged grinding jobs; encoders implement precise closed-loop position control.
Typical Applications:
• High-load cordless metal, stone and jade engraving handheld power tools
• Heavy-duty salon polishing machines and commercial-grade beauty care equipment
• Benchtop automated deburring fixtures and medium-load material processing modules
• Mid-sized robotic joint actuators needing strong torque output
