KSM01.2B-071C-24N-M1-HG2-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

Bosch Rexroth Indramat manufactures the KSM01.2B-071C-24N-M1-HG2-SE-NN-D7-NN-FW as part of its KSM Motor Integrated Servo Drives series. This motor-integrated servo drive combines a 071-frame permanent-magnet servo motor with embedded power electronics, reducing cabinet space in modular machines. The unit controls position, speed, and torque directly at the axis, enabling decentralized motion in packaging, handling, and assembly cells.

Power and control wiring are combined in a single hybrid connector, which simplifies installation and limits the number of separate cable runs to the axis. Heat from the integrated inverter is removed by natural convection, eliminating the need for fans. Feedback is processed through a Hiperface interface, which transfers position data and stored parameters to the drive. The optical scale inside the encoder is divided into 128 signal periods, providing fine incremental data for smooth velocity regulation. Real-time commands reach the drive over SERCOS 2 (RS-422), supporting deterministic update cycles across multi-axis networks. Winding code 24 and the basic performance level support applications with moderate throughput requirements.

The holding mechanism is an electrically released brake that clamps the rotor whenever control power is lost and disengages when commanded. Its coil is energized at DC 24 V, allowing the brake interface to operate with common machine control supplies. DC bus energy for the power stage is supplied at DC 750 V, supporting high peak torque without requiring higher motor current. A plain shaft allows direct coupling to gearboxes or belt pulleys, while an integrated shaft seal helps protect the enclosure from contaminants. The unit has motor length C and design version 2, and it does not include integrated safety technology.
