FSM430
by Kollmorgen
The Kollmorgen FSM430 from the FSM Brushless Servo Motors series is a high-performance servo motor engineered for precision motion control in industrial automation. This compact 8-pole unit delivers a maximum speed of 4000 rpm and features a low rotor moment of inertia of 0.0010 kg·m² for rapid acceleration and deceleration. With a torque constant (sine wave) of 0.54 Nm/A, it provides accurate, repeatable torque output for demanding positioning tasks.
Designed for robust industrial applications, the FSM430 offers a winding resistance of 2.24 Ω and a winding inductance of 6.8 mH to ensure stable current regulation. Its KE voltage constant of 66 V/krpm optimizes back-EMF control, while a damping coefficient of 0.06 Nm/krpm and friction torque of 0.063 Nm minimize oscillations and enhance steadiness. The 8-pole configuration contributes to smooth operation and high resolution, distinguishing this motor in precision servo systems.
Durable and efficient, the FSM430 withstands harsh conditions with a dielectric strength rating of 1500 VACrms and a thermal resistance of 0.63 °C/W for improved heat dissipation. Weighing 9.1 kg, this unit balances structural rigidity with manageable mass for diverse machine integrations. With both sine and square wave torque constants of 0.54 Nm/A and 0.56 Nm/A respectively, it adapts to varied drive architectures. The FSM430’s reliable insulation and low thermal rise ensure long service life and reduced maintenance. Ideal for precision indexing, robotics, and CNC applications, it enhances throughput and process stability in industrial environments.
