KSM02.1B-061C-61N-M3-HP0-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M3-HP0-ET-NN-D7-TO-FW is a motor-integrated servo drive from Bosch Rexroth Indramat that belongs to the KSM Motor Integrated Servo Drives series. It combines a synchronous servo motor and a compact inverter in one housing, reducing the amount of equipment required in the control cabinet. The integrated arrangement also shortens the external wiring needed for distributed automation systems and provides closed-loop control at the machine axis.

The drive operates from a 750 V DC power bus and dissipates heat through natural convection, so it does not require forced-air fans in the field enclosure. Power, communication, and feedback lines are routed through a single hybrid connector, which reduces the number of separate cable connections. Motion commands reach the device through a Multi-Ethernet interface, allowing communication with compatible machine control networks. The product is part of Series 2 and uses design version 1. Rotor position is monitored by a Hiperface encoder that delivers 16 signal periods per mechanical revolution. Its capacitive sensing element resists interference from magnetic dust and oil encountered around industrial machinery. The encoder stores feedback through a multi-turn absolute counter, allowing the axis to retain position data after a power cycle. The motor has size 061, length C, and winding code 61, which indicate its physical configuration and electrical characteristics.

The output uses a shaft with a keyway for positive engagement with gears, pulleys, or rigid couplings. A shaft seal helps prevent coolant spray and oil mist from reaching the bearing assembly. The unit is supplied without a holding brake, so an external holding mechanism is required if the load must remain fixed after motor torque is removed. This arrangement is suitable for horizontal axes that do not require brake-assisted parking. Its performance level is classified as Basic. Integrated safety technology is not included, so external safety devices must provide functions such as safe torque off or safe stop 1 when those functions are required by the machine design.
