Bosch Rexroth KSM01.2B-041C-42N-M1-HP2-SE-NN-D7-NN-FW Servo Motor

The Bosch Rexroth KSM01.2B-041C-42N-M1-HP2-SE-NN-D7-NN-FW is a motor-integrated servo drive from the IndraDrive Mi family, combining a high-performance servo motor and drive electronics in a compact, single housing to simplify installation, wiring, and tuning in demanding automation environments. In the 041C-42N variant, the integrated unit delivers precise, variable-speed torque with a maximum speed of 5,500 rpm, a stall torque of 2.2 Nm, and a peak torque of 9.4 Nm, providing robust response for fast positioning and load changes. Electrical characteristics include continuous current at standstill of 1.5 A and a maximum current of 6.8 A, while inertial load is 0.00017 kgm² and the complete assembly weighs around 5.5 kg, translating to a compact footprint suitable for mounting in tight spaces. The device supports SERCOS 2 (RS-422) communication and uses a hybrid connector for streamlined connectivity, enabling reliable closed-loop control and easy integration into Rexroth automation architectures, making it a compelling choice for applications requiring precise motion, repeatability, and simplified wiring.
