KSM02.1B-061C-35N-M3-HP0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M3-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By housing the power electronics directly on the motor, it simplifies decentralized motion axes and eliminates the need for long motor cables or cabinet-mounted inverters in production lines and packaging machines. This compact unit processes torque and position commands close to the mechanical load, supporting responsive control while reducing the amount of equipment installed in the main control cabinet.

The drive operates from a supply of 750 V DC, allowing it to connect to the common DC link of a compatible multi-axis system without an additional converter. Power, feedback, and Ethernet lines pass through a single hybrid connector, reducing the number of wiring points and simplifying cable routing. A natural convection cooling system transfers heat through the cast housing without fans or liquid cooling equipment. Position data is exchanged through a Hiperface interface, which supports electronic motor data and automatic scaling within the controller. Network traffic uses Multi-Ethernet communication, allowing the drive to operate with SERCOS III, EtherNet/IP, or PROFINET when configured for the selected industrial network.

Rotor angle is measured by a capacitive sensor system that provides multi-turn absolute tracking across 16 signal periods, so the axis can retain position information after a loss of power. Mechanical output is transmitted through a shaft with a keyway, providing positive engagement with a compatible coupling or driven component. A shaft seal protects the internal bearings from oil spray and other contaminants near the drive end. The product is a Series 2 device with winding code 35, motor size 061, and motor length C. It has a basic performance level, design version 1, and a standard mechanical option, and it is supplied without a holding brake or integrated safety technology.
