Product Description:

The KSM02.1B-041C-42N-S1-HG2-ET-S3-D7-NN-FW is produced by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. It combines a synchronous motor and a drive controller in one housing, reducing cabinet wiring and shortening installation time in distributed automation layouts. Within packaging cells, assembly stations, or compact gantries, the unit delivers torque and closed-loop speed control directly at the axis, allowing motion tasks to be decentralized while still using a central DC-bus power supply.

The drive is powered from a DC 750 V bus, and connections are made through a single Hybrid Connector that carries both power and fieldbus lines. Heat is removed solely by natural convection, so no external fans or liquid circuits are required. Communication with higher-level PLCs is handled by a Multi-Ethernet interface that supports common industrial Ethernet variants. Position feedback comes from a Hiperface optical encoder, and the single-turn design fits applications that index within one mechanical revolution. The standard mechanical option is design version 1, and it is supplied with a plain shaft and a shaft seal. Winding code 42, motor length C, and series 2 correspond to the electromagnetic configuration used for continuous operation with natural cooling.

An electrically released holding brake engages at DC 24 V, preventing axis drift when power is removed. The optical encoder resolves motion into 128 signal periods, supporting fine velocity regulation without high data traffic. Integrated Safe Motion (without SBC) functions permit hardware-based monitoring of speed and standstill for Category 3 safety circuits. With motor 041 frame size, the unit occupies minimal space while still providing the torque expected from this length class.
