FANUC A06B-0202-B400 α1/5000i Straight Shaft AC Servo Motor with Brake

The FANUC A06B-0202-B400 α1/5000i is a straight shaft 0.5kW AC servo motor with a 24VDC brake and α1000iA pulsecoder. It is designed for CNC machines requiring both a straight shaft mechanical interface and brake holding support. This model is often used on compact feed axes, vertical or holding axes, positioning units, and industrial automation equipment using FANUC CNC systems. The brake function helps support axis position retention, while the straight shaft structure must match the machine coupling. It is suitable for CNC repair, spare parts replacement, and machine tool maintenance.
