FSM460
The Kollmorgen FSM460 from the FSM Brushless Servo Motors series is a high-performance brushless servo motor offering a Max operating speed 4000 rpm and a radial load @4000 rpm 44 lb (20 kg). Featuring an exceptionally low rotor inertia 0.0011 kg·m², it delivers rapid acceleration and precise motion. Its thermal management is optimized with a thermal resistance 0.63 °C/W, while the winding resistance 2.24 Ω (±15%) and Poles 8 ensure efficient electrical performance. Weighing just 9.1 kg (20 lb) without brake and 10.9 kg (24 lb) with brake, it balances power and compact size for demanding industrial applications.
