Product Description:

The KSM02.1B-041C-42N-M1-HG0-ET-S3-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servo motor with an onboard power stage, it streamlines installation in modular automation cells and packaging lines that require distributed, synchronized motion. The 041 frame size provides continuous torque for small indexers and pick-and-place axes where compact dimensions and direct axis integration are important.

Power is supplied from a DC bus at 750 V, which reduces the need for additional inverter hardware inside the cabinet and supports shorter cable runs. Heat from the electronics is removed through natural convection, so no external fan or liquid loop is required. The single-cable layout uses a hybrid connector for power, control, and safety signals. The drive uses winding code 42, which indicates the electrical winding arrangement for this motor version. Rotor position is transmitted through a Hiperface interface that uses 128 signal periods from an optical scanning system, and a multi-turn track keeps count of revolutions.

The motor uses the longer C stack to increase continuous torque without widening the flange. It is assigned the Basic performance level, which suits applications that need synchronized motion without added feature complexity. Integrated SafeMotion provides Safe Motion (without SBC) functions through dedicated inputs and complies with EN 61800-5-2. Communication is handled over Multi-Ethernet through the external master interface. The servo is delivered without a holding brake, so vertical axes require external mechanical locking. A shaft seal helps protect the output end from coolant splash and dust, and the output uses a plain shaft for straightforward coupling alignment.
