Engineering Overview
FA-1650RB ultra-long coreless brushless DC motor eliminates brush friction to extend service life and lower electromagnetic interference. Uniform low rotor inertia delivers fast response and smooth cogging-free rotation at ultra-high speeds. Dual 12V and dual 24V winding options provide flexible speed-torque matching for different power supply systems. Ball bearing structure supports long-hour continuous operation, and matched gearbox & encoder can realize precise heavy-load closed-loop control.
Typical Applications:
• High-speed portable beauty & dental equipment
• Medium-sized robot drive actuators
• Mini industrial automated transmission modules
• Compact high-speed precision testing instruments
