Product Description:
The KSM02.1B-061C-35N-S3-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining drive electronics with the servo motor housing, the unit provides decentralized axis control in automation lines that favor compact installations. It uses the standard design option in design version 1 and a basic performance level. The product is in Series 2, and its integrated layout reduces the need for a separate drive enclosure close to the axis. This arrangement helps place the power electronics directly at the machine axis, which can reduce cabinet space and shorten motor cable runs in distributed systems.
The drive accepts a DC 750 V supply bus and dissipates heat through natural convection, eliminating the need for forced air or liquid cooling. Power, signal, and brake conductors converge in a single hybrid connector, which shortens wiring runs and keeps the connection point compact. Network integration is handled by a Multi-Ethernet interface, giving the master controller access to real-time status and parameter data. Position feedback is returned over the Hiperface channel for closed-loop control. The combined connection layout also reduces the number of separate cable entry points on the machine frame. Rotor energization characteristics are set by winding code 35, while the mechanical envelope corresponds to motor length C.
An electrically released brake holds the shaft motionless when power is removed and engages at DC 24 V. Motion resolution is provided by the encoder’s 16 signal periods, giving the controller fine incremental positioning. The assembly carries a shaft seal to guard the bearing set against coolant and dust, and it is built on frame size 061, which balances torque capacity with low inertia. A plain shaft output eases coupling to gearheads or belt pulleys without keys. The brake supports load holding during standstill, while the sealed shaft area helps protect internal components in dusty or wet surroundings.
