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

The KSM02.1B-076C-35N-M3-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 a permanent-magnet servo motor, drive electronics, and a fieldbus interface in one housing, allowing installation on a machine without a control-cabinet inverter. This arrangement supplies point-of-use motion power for packaging lines, material-handling systems, and assembly cells while the central controller communicates through the onboard Ethernet network.

The drive accepts a bus voltage of DC 750 V, and power, signal, and brake conductors are routed through a single hybrid connector. The enclosure relies on natural convection for passive cooling, eliminating maintenance components such as fans. Command and diagnostic data pass through the Multi-Ethernet interface, while position data returns through a Hiperface link. The motor has a size of 076, a length of C, and a winding code of 35. It is design version 1 and uses the standard design option. The plain shaft mates directly with couplings, and a shaft seal helps prevent lubricant leakage and contaminant entry. The unit has a basic performance level and belongs to Series 2. It does not include integrated safety technology, so torque-off or safe-motion functions must be provided externally.

The feedback system resolves each rotation into 16 signal periods using a capacitive sensing element that resists interference from stray magnetic fields. Multi-turn absolute tracking retains position across power cycles, simplifying restart routines by removing the need to establish the position again. Load holding is handled by an electrically released brake energized at DC 24 V. The brake clamps automatically when the control supply is lost, helping prevent unintended shaft movement. Shaft sealing protects the bearing area, while passive cooling removes operating heat without requiring an external fan or liquid-cooling circuit.
