Product Description:

The KSD061C-0350-NN-M3-1G2-NNNN is a decentralized servo motor from the KSD IndraDrive Mi Motors series manufactured by Bosch Rexroth Indramat. By integrating drive electronics directly on the motor housing, it simplifies cabling and enables modular machine layouts where motion axes can be added without requiring extra control cabinet space. In automated packaging, handling, or printing lines, the unit delivers position-controlled rotary motion while exchanging power, control, and safety signals over a single hybrid cable.

The motor sustains 6.0 Nm of continuous torque at a 60 K winding temperature rise, allowing stable operation during duty cycles that keep the stator well below insulation limits. During acceleration or shock loading, it can reach a peak torque of 25.0 Nm, providing capacity for rapid indexing moves without oversizing the frame. The drive electronics may draw up to 14.9 A of phase current; this ceiling guides fuse sizing and busbar capacity. With a torque constant of 2.03 Nm/A, each additional ampere contributes predictable mechanical output, simplifying current-loop tuning. The rotor’s mass moment of inertia is 0.00093 kg·m², so speed commands are followed quickly while overshoot is minimized. The integrated brake provides a static holding torque of 10.00 Nm to keep vertical loads secure when power is removed. The back-EMF coefficient of 125.0 V/1000 rpm assists the drive with voltage scaling and regeneration calculations.

Thermal behavior is characterized by a 18 min time constant, meaning winding temperature changes are gradual enough for the drive to react before limits are reached. The motor uses thermal class 155 insulation. Mechanical integration is aided by an M6 centering hole and a shaft with a nominal diameter of 19 mm and a k6 tolerance. The brake adds only 0.0000590 kg·m² of inertia, so stopping performance remains responsive. Torque is transmitted through a keyed connection that accepts a 6 × 6 × 32 mm key, allowing properly sized couplings or pulleys to be fitted to the shaft.
