Product Description:

The KSM02.1B-041C-42N-M1-HP2-ET-NN-D7-TO-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining power electronics, communication hardware, and a synchronous motor in one enclosure, it provides decentralized axis control for pick-and-place units, forming presses, and similar automated machinery. Mounting the drive directly on the machine frame shortens feedback and power runs, helping reduce electromagnetic interference in multi-axis systems while keeping cable routing cleaner.

This unit accepts a supply of DC 750 V, allowing it to connect directly to common high-voltage DC bus systems fed by regenerative or front-end converters. A single Hybrid Connector carries motor power and the communication link, so only one cable is needed between the axis and the machine harness. Cooling relies on natural convection, so the housing dissipates heat without fans and avoids added airflow hardware. The integrated encoder uses the Hiperface digital interface and provides 128 signal periods per mechanical revolution; this optical multi-turn device supplies absolute position data to the controller after power cycling. Axis holding is provided by an electrically released holding brake energized at 24 V DC, so the rotor locks automatically when control power is removed and helps maintain load position during emergency stops or power loss.

Mechanical sizing follows motor size 041 with length code C, giving the unit a compact form for light to medium loads. Torque is transmitted through a shaft with a keyway, which supports direct coupling to gearboxes or belt pulleys and helps prevent slip under peak load. The controller function set is rated Basic, and any required safe torque off or safe motion must be provided by upstream equipment. This arrangement suits distributed servo layouts where compact installation and integrated motor-drive packaging are important.
