Product Description:

The KSM01.2B-041C-42N-S1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It unites a synchronous motor, power stage, and feedback package in one enclosure, so fewer external components are required on the machine frame. The product is intended to provide precise torque and position control for decentralized axes in material-handling and assembly lines where cabinet space is limited. Because the inverter electronics are integrated into the motor housing, the unit supports compact machine layouts and short motor-side connections. This arrangement places the drive section directly at the axis for distributed automation tasks.

The drive draws from a DC 750 V intermediate circuit and routes both supply power and low-level signals through a single Hybrid Connector, which simplifies cable routing on moving or rotating tooling. Thermal energy is removed by natural convection, so no fans or liquid cooling plates are fitted. Rotor position is reported through a Hiperface encoder that uses 128 signal periods per revolution in an optical single-turn system, supporting fine interpolation inside the controller. The encoder feedback gives the controller the position data needed for stable speed and torque regulation during motion. The C-length stator keeps the motor section compact, and a shaft seal is installed to limit particle ingress at the output journal. Design version 2 uses the basic performance level and omits an internal brake.

Field networking is handled over SERCOS 2 (RS422), so cyclic position, velocity, and diagnostic telegrams stay synchronized with the system master without separate wiring. The communication link supports coordinated operation across distributed automation axes. The motor side uses a plain shaft, permitting direct coupling to gearheads or belt pulleys without key chatter. Size code 041 is paired with winding code 42 for mid-range continuous torque while keeping current demand suitable for decentralized power systems. This layout is useful where compact axis modules are mounted close to conveyors, transfer units, or indexing mechanisms.
