Engineering Overview
FA-3265RC is our flagship 50W heavy-duty coreless brushed motor designed for long-cycle industrial operation. It features thick graphite brushes and a 13-segment oversized commutator to cut brush wear and extend service life under high current and frequent stall conditions.
Its extra-long rotor delivers large rotor inertia for steady speed under variable heavy loads. Two distinct 12V winding options plus 24V and 48V grades are available; the 48V version provides outstanding 1612mNm stall torque for high starting power. Short mechanical time constant ensures fast dynamic response. Paired with gearboxes and encoders, it supports high-precision closed-loop heavy-load control.
Typical Applications:
• Humanoid robot heavy joint actuators
• Industrial heavy transmission devices
• High-pressure large-flow micro pumps
• 48V heavy-duty industrial portable machines
• Lab precision high-load equipment
