Product Description:

Bosch Rexroth Indramat manufactures the KSM02.1B-041C-42N-S1-HG2-ET-SD-D7-TO-FW as part of the KSM Motor Integrated Servo Drives series. By combining power electronics, feedback, and a 041 frame-size synchronous motor inside one enclosure, it provides decentralized positioning for machines that need compact axis control. This arrangement places the drive directly at the axis, reducing the need for a separate motor cable between a cabinet-mounted amplifier and the motor. It is well suited to machine sections where installation space is limited and distributed motion control is preferred.

The drive is powered from a DC 750 V supply and receives power, safety I/O, and network lines through a single Hybrid Connector, which reduces cabinet wiring. Heat is removed by natural convection, so no fans or liquid circuits are required. Position feedback is delivered through a Hiperface optical encoder that offers 128 signal periods per revolution. This single-turn device supports smooth speed regulation without multi-turn tracking. Multi-Ethernet master communication and a dedicated Multi-Ethernet output coupling are embedded for real-time data exchange with several fieldbus variants. The unit is design version 1 with performance level Basic and series 2. The C-length stack pairs with winding code 42 to balance continuous torque and inertia, and a factory-installed shaft seal protects the internal bearings from splash ingress.

An electrically released holding brake rated at DC 24 V secures the load whenever bus power is absent, while the integrated Safe Motion function with Safe Motion (with SBC) hardware meets stop-category requirements without external relays. Output torque is transmitted through a plain shaft, allowing direct coupling to gears or pulleys. The hybrid connector has a radial cable exit, and the shaft seal supports vertical or horizontal mounting without further adapters. The brake helps hold the axis in place during standstill or power loss, and the radial cable exit can help where there is limited clearance around the motor body.
