KSM02.1B-076C-35N-S1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. Combining power electronics, feedback, and communication in a single housing, it mounts directly on machinery to save cabinet space and reduce wiring. In automated assembly lines or packaging cells, the unit delivers coordinated motion while reducing the electromagnetic loop area because the amplifier sits at the motor flange.

The drive uses a single hybrid connector that carries DC-bus power, signals, and safety I/O in one molded interface, simplifying installation and maintenance. Heat is removed solely through natural convection, so no fans are required and the housing can be sealed against dust. A shared DC link of 750 VDC feeds the embedded inverter, allowing multiple axes to run from the same supply without separate mains filters. The motor has a frame size of 076, providing a midrange diameter that balances torque density with footprint. Internal winding code 35 adapts the stator copper to the expected current profile and matches the C-length option for the intended duty cycle.

Rotor position is measured through a Hiperface interface, providing high-speed digital feedback at a base resolution of 128 signal periods. The sensing element is an optical disk with low hysteresis, and its single-turn design reports absolute position over one revolution. This arrangement is suitable for point-to-point machines that perform a homing sequence after power-up. For deterministic network traffic, the controller supports Multi-Ethernet, so EtherNet/IP, PROFINET, or EtherCAT can be selected in software without hardware changes. The plain shaft is protected by a factory-installed seal, and the unit is supplied without a holding brake, making it suitable for belt-driven or horizontally oriented loads. The unit has design version 1 and the Basic performance level.
