Engineering Overview
FA-2260RB flagship 35W coreless brushless DC motor eliminates iron cogging torque and brush mechanical abrasion, delivering ultra-smooth low-vibration rotation, low EMI interference and ultra-long service life. Double heavy ball bearing structure greatly improves radial load resistance, stable under continuous heavy-duty operation. Low mechanical time constant & moderate rotor inertia enable ultra-fast acceleration/deceleration under frequent start-stop cycles. Wide industrial voltage coverage (12V/24V/30V) covers low-speed high-torque and ultra-high-speed heavy-load working modes. Complete matching portfolio including planetary gearbox and dual-type encoders supports high-precision closed-loop torque, speed and position control for high-end industrial micro equipment.
Typical Applications:
• Heavy-load humanoid robot joint actuators
• High-power medical surgical handheld instruments
• Industrial miniature high-torque transmission modules
• High-precision laboratory polishing & grinding equipment
• Portable high-speed carving & engraving power tools
