Engineering Overview
FA-2060RB ultra-long 20W coreless brushless DC motor completely eliminates iron cogging torque and mechanical brush abrasion, realizing ultra-smooth low-vibration rotation and extremely long continuous service life with low electromagnetic interference. The thickened ball bearing structure greatly improves radial load resistance, making it suitable for high-speed impact working scenarios. Low rotor inertia delivers ultra-fast acceleration and deceleration response under frequent start-stop cycles. Multi industrial voltage options (12V/24V/36V) match mainstream industrial power supply standards, and huge stall torque provides powerful overload capacity. Matched gearbox amplifies output torque for heavy-load micro robots, dental polishing equipment and portable carving power tools.
Typical Applications:
• Heavy-load micro robot joint actuators
• Dental polishing & manicure grinding handheld equipment
• Mini jade carving and engraving power tools
• Industrial miniature automated transmission modules
