Product Description:

The KSM02.1B-041C-42N-S1-HG0-ET-NN-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics with the servo motor in a single housing, it allows decentralized motion control on machines where cabinet space is limited. This unit is intended to position and regulate the velocity of individual axes directly on moving machine parts, reducing wiring and improving modularity in automated assembly, packaging, and handling equipment.

The drive draws energy from a DC 750 V shared supply bus, giving it the headroom required for rapid torque transients. Power, encoder signals, and fieldbus wiring are consolidated in one Hybrid Connector, which shortens installation time and reduces potential connection errors. Thermal management relies on natural convection; no fans are fitted, so operation remains quiet and there are no moving parts to maintain. Feedback is provided through a Hiperface optical encoder, ensuring digital position data that is not affected by analog drift. Resolution is fixed at 128 signal periods per mechanical revolution, so the control loop can detect very small incremental changes in position.

The encoder is a single-turn device, so absolute position is retained for one revolution, while multi-revolution tracking is handled at the controller level when needed. The motor has a plain shaft with an integral shaft seal that helps prevent lubricant escape and blocks dust ingress. Electromagnetic characteristics follow winding code 42, matched to drives that deliver rated current in the medium torque range. Frame dimensions correspond to motor size 041 and the C length class, balancing continuous torque with compact depth. The design omits a holding brake and advanced safety functions, reflecting its placement in the basic performance level where external mechanics or higher-level controls handle those tasks.
