Product Description:

The Bosch Rexroth Indramat KSM02.1B-041C-42N-M1-HP2-ET-S3-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series and combines a synchronous motor with an onboard inverter. This motor-integrated construction lets machine builders place the unit directly on moving axes while eliminating separate drive cabinets. Designed for single-axis control in automated packaging, handling, and assembly equipment, it receives DC bus power, generates torque through its permanent magnets, and returns absolute position data to the higher-level controller.

The drive operates from a DC 750 V supply delivered over a single Hybrid Connector that carries power, Ethernet, and safety signals. Rotor position is measured through a Hiperface optical encoder that produces 128 signal periods per mechanical revolution, providing fine resolution for velocity and position loops. An electrically released brake is installed, and its coil is energized with DC 24 V to hold loads when power is removed. The motor has size 041, length C, and winding code 42, which give the axis its continuous torque and speed range. The design option is Standard, the performance level is Basic, and the device is design version 1 in series 2. Optical sensing, multi-turn absolute tracking, and a shaft seal complete the feedback and shaft-end arrangement.

Control data reach the unit through a Multi-Ethernet interface that supports EtherNet/IP, PROFINET, and other real-time fieldbuses. Integrated safety complies with Safe Motion (without SBC), enabling certified functions such as safe stop and limited speed without extra relays. Heat is removed solely by natural convection, so no fan maintenance is required. A shaft with keyway transfers torque to couplings or pulleys, while the built-in shaft seal helps prevent lubricant escape and particle ingress. The single-connector layout keeps power, communication, and safety connections together at the unit.
