KSM02.1B-076C-35N-M1-HG2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HG2-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By placing the power electronics directly on the motor body, the device reduces the need for remote control cabinets and supports decentralized automation on packaging, assembly, and material-handling lines. This integrated arrangement shortens the connections between the motor and drive electronics while reducing the amount of cabling routed through the machine. The unit provides closed-loop speed and position regulation for automated axes that require basic performance and compact installation.

Thermal management relies on natural convection, so the housing requires unobstructed airflow but does not need an active fan. Rotor position is monitored by a Hiperface optical encoder that generates 128 signal periods per revolution and retains multi-turn position data when power is removed. An electrically released brake grips the shaft after power is removed from its coil, allowing the motor to hold a stationary load. The brake coil operates at DC 24 V while the shaft is released for motion. The motor has a plain shaft with a shaft seal that helps prevent contaminants and splashing liquids from reaching the internal components, while winding code 35 provides the electrical characteristics required by the integrated drive.

Power, control, and feedback lines terminate in a hybrid connector, simplifying cable routing on linear machines and other distributed automation systems. The drive operates from a DC 750 V bus, allowing compatible units to share power through a common DC connection. Commands and status data are exchanged through Multi-Ethernet communication, which supports connection to EtherCAT, PROFINET, or EtherNet/IP control networks without separate interface cards. Integrated Safe Motion without SBC provides safety functions through dedicated inputs but does not include Safe Brake Control. The motor has size 076 and length C, providing the physical format associated with this model. It uses the standard design option, design version 1, and Series 2 configuration while maintaining the basic performance level assigned to the KSM platform.
