KSM02.1B-076C-35N-M1-HG2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines power electronics with a synchronous motor in one enclosure, allowing decentralized control of axes on machines, conveyors, and material-handling systems without a separate cabinet-mounted inverter. Locating the drive near the load reduces the required motor cabling and supports compact machine layouts. The unit belongs to Series 2 and uses a standard design option with design version 1.

The drive stage operates from a DC 750 V supply connected to the high-voltage DC link used in modular automation systems. Motion commands and diagnostic data are transmitted through Multi-Ethernet, which supports communication with compatible real-time Ethernet networks. Rotor position is measured through a Hiperface feedback channel connected to an optical, multi-turn absolute encoder. The encoder provides 128 signal periods per revolution and retains absolute position information across multiple shaft rotations. Heat is dissipated through natural convection, eliminating the need for cooling fans or liquid circuits. The unit has a basic performance level and does not include integrated safety technology. Motor size 076 and frame length C establish the housing dimensions, while winding code 35 identifies the electrical configuration used for this motor frame.

An electrically released brake holds the shaft when the brake coil is not energized, helping prevent unintended movement while system power is removed. The brake operates from DC 24 V and releases after the controller energizes its coil. Power, communication, and brake conductors connect through a single hybrid connector, reducing the number of separate cable connections required at the motor. Output torque is transmitted through a plain shaft, which is suitable for clamping couplings and other friction-based connections. A shaft seal limits the entry of coolant and lubricants around the output shaft, helping protect the internal bearing area during operation. The sealed interface also supports installation near machinery where occasional fluid exposure may occur.
