KSM02.1B-076C-35N-M3-HP0-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M3-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By integrating power electronics, feedback conversion, and a permanent-magnet servomotor into one compact housing, the unit provides decentralized motion control for automated assembly cells, material-handling stations, and other industrial axes that benefit from reduced cabinet space and short cable runs. This arrangement simplifies installation and reduces electromagnetic interference during high-speed indexing tasks. Locating the control electronics at the motor also reduces the amount of wiring required between the machine and the control cabinet.

The drive operates from a bus-fed supply of DC 750 V, allowing multiple drives to share a common intermediate circuit and recover braking energy. Command data reach the drive through a Multi-Ethernet interface that supports several real-time industrial communication protocols without additional hardware. Position feedback uses a Hiperface link connected to a capacitive multi-turn absolute encoder. The encoder produces 16 signal periods per revolution for accurate position interpolation. The integrated safety system provides Safe Torque Off, which disables torque-producing power when a safety stop is requested. Winding code 35 indicates the electrical arrangement used for this motor size, while design version 1 and the Basic performance level identify the drive configuration for the Series 2 platform.

The motor has a frame size of 076 and a length code of C, providing a compact housing for decentralized installation. Its steel output interface is a shaft with a keyway, allowing pulleys or rigid couplings to transmit torque without slipping. A shaft seal protects the internal bearings from coolant and dust entering around the output shaft. Heat is removed through natural convection, eliminating the need for fans and supporting installation outside a conventional control cabinet. Power, signal, and brake conductors are routed through a single hybrid connector, reducing the number of separate cable connections required at the motor. The unit has a standard design option and is supplied without a holding brake, so an external method must secure the load when holding force is required after power is removed.
