FA-2330RD Two-Pole Coreless Brushless DC Motor
FA-2330RD is a high-performance 25W two-pole coreless brushless DC motor with Φ23 outer diameter and 30mm long body. Equipped with precision double ball bearings for heavy load and long service life, two-pole slotless rotor delivers ultra-fast dynamic response and zero cogging torque. Built-in 3-channel hall sensor supports stable closed-loop speed regulation. Four winding options cover 7.4V lithium, 12V, 24V, 30V industrial voltages. Matched G22MF planetary gearbox and EM22 incremental/absolute encoders are available for medium-load precision equipment.

Engineering Overview
FA-2330RD two-pole coreless BLDC adopts ball bearing structure, greatly improving load capacity and service life compared to sleeve bearing micro motors. Two-pole low-inertia rotor brings fast start-stop and smooth low-variable rotation without cogging torque. Split power & signal wiring effectively avoids electromagnetic interference. Wide voltage range covers lithium handheld devices and 12/24/30V miniature automation systems. Matched G22MF gearbox amplifies torque for medium-load polishing, grinding and precision adjustment equipment.
Typical Applications:
• High-power nail drills, jade miniature carving handheld tools
• Portable medical beauty instruments, facial deep cleaning equipment
• Miniature industrial deburring & surface polishing devices
• Small automated optical focusing and testing modules
