KSM02.1B-041C-42N-S3-HG2-ET-NN-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-S3-HG2-ET-NN-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It combines drive electronics with a synchronous motor in one housing, allowing distributed axes to operate without separate cabinet-mounted drives. This arrangement reduces wiring between the control cabinet and motor while conserving enclosure space. The unit provides basic performance for controlled motion in assembly lines, packaging equipment, and material-handling systems.

The drive accepts a bus supply of DC 750 V from a shared DC link. Its internally mounted, electrically released brake uses a control voltage of DC 24 V to release the shaft during operation and secure it when power is removed. Heat from the motor and power electronics is dissipated through natural convection, eliminating the need for a cooling fan. Power, feedback, and network conductors pass through a single hybrid connector, which supports compact cable routing and daisy-chain installation. Position data is supplied by a Hiperface encoder with a capacitive single-turn measuring system, providing the drive with rotor position information after startup. The motor uses a plain shaft with a shaft seal, allowing direct coupling while helping prevent lubricant loss and contaminant entry.

Ethernet-based motion commands are exchanged through Multi-Ethernet ports associated with the external master communication option. Encoder feedback provides 16 signal periods per electrical revolution, supporting interpolation for position and speed control. The motor has a size 041 frame with winding code 42N, and its frame length is C. The winding determines the electrical characteristics used by the drive to regulate torque across the operating range. The actuator uses design version 1 hardware and Series 2 electronics. It does not include additional integrated safety technology, so required safety functions must be provided by the higher-level control system or separate safety equipment.
