KSM02.1B-076C-35N-M3-HG2-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M3-HG2-ET-NN-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It combines a servo motor, power stage, and network interface in one housing to provide decentralized motion control for conveyors, pick-and-place axes, and other automated stations. This arrangement eliminates separate cabinet drives and reduces the number and length of cable runs on the machine frame.

A single hybrid connector carries DC bus power, logic power, fieldbus signals, and brake conductors, so installation requires only one molded cable. Heat is removed through natural convection, allowing the drive to operate without forced airflow. The internal inverter accepts a rectified supply of 750 V DC from a shared bus, making it suitable for multi-axis machines that use a central regenerative supply. Feedback is handled through a Hiperface interface, and the capacitive encoder produces 16 signal periods per mechanical revolution to support precise position measurement. The Multi-Ethernet interface supports EtherNet/IP, PROFINET, EtherCAT, and Sercos communication without hardware changes. The unit has design version 1, a Basic performance level, and Series 2 electronics.

The holding mechanism is an electrically released brake that engages when control power is lost and disengages when supplied with 24 V DC. A frame size of 076 and motor length C establish the stator dimensions. The motor has a plain shaft without a keyway for transmitting torque to couplings or gearheads, and a shaft seal helps block dust and oil spray. Winding code 35 identifies the stator winding used with the natural-convection cooling system. The multi-turn absolute encoder retains position information across power cycles, while its capacitive sensing technology resists magnetic interference. The unit does not include integrated safety technology, so any required functional safety must be provided by external devices. Power, communication, feedback, and braking functions are integrated into the motor housing to reduce the number of separately mounted components on the machine.
