Product Description:

The KSD061C-0610-NN-M1-1G0-NNNN is a compact servo motor-drive module produced by Bosch Rexroth Indramat for the KSD IndraDrive Mi Motors series. By integrating the inverter stage with the synchronous motor, the device mounts close to the work axis and reduces cabinet wiring in multi-axis automation. It is used in packaging, material-handling, and assembly lines where decentralized drives shorten installation runs and support coordinated motion through a shared DC bus. This arrangement also helps keep motor and drive components together in one machine-mounted unit.

The drive develops a continuous shaft torque of 5.5 Nm under rated thermal conditions. This output comes from a winding design with a torque constant of 1.16 Nm/A, so phase current is converted into proportional mechanical torque. At the operating point, the electromagnetic system delivers 800 W of mechanical power, while the internal voltage generator produces 71.5 V/1000 rpm as back EMF during operation. Current peaks are limited to 14.9 A, which affects inverter sizing and conductor cross-section. Supporting components include a DC-bus capacitor for link-voltage stabilization during load changes, and the listed rotor inertia supports a balance between acceleration response and position stability.

Dynamic reserve is available through a peak torque ceiling of 18.0 Nm, allowing short bursts to overcome friction or start inertial loads. Position data are captured by an optical encoder that provides 128 × 2¹³ counts/rev resolution across 4096 turns, enabling fine interpolation over extended travel. The assembly weighs 9.5 kg, which helps provide a solid mounting mass while remaining practical for integrated machine axes. Thermal equilibrium is reached with a time constant of 18 min, giving the controller time to respond to intermittent overload before winding temperature rises too far. The multi-turn feedback system also supports applications that need precise position tracking over repeated revolutions.
