KSM01.2B-076C-35N-S1-HP0-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-076C-35N-S1-HP0-SE-NN-D7-NN-FW motor-integrated servo drive is produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It combines a synchronous motor, feedback electronics, and an embedded inverter in one housing, creating a decentralized axis that connects directly to a DC bus and field network. The device is installed in machinery where compact motion modules shorten cable runs and simplify plant layouts for automated handling, packaging, and assembly stations.

The drive accepts a supply of DC 750 V, so its power stage connects to a common high-voltage bus rather than individual AC mains. Heat is removed solely by natural convection, eliminating the need for fans or liquid cooling in protected mounting locations. A single hybrid connector carries power, logic, and motor temperature leads, which simplifies installation and reduces enclosure bulk. Real-time command and status data move over SERCOS 2 (RS-422), providing deterministic cycle times for coordinated multi-axis motion. Position feedback is supplied by an optical Hiperface encoder that resolves the shaft into 128 signal periods per revolution, providing suitable granularity for moderate-precision indexing applications.

The rotor transfers torque to the load through a shaft with a keyway, and a factory-installed shaft seal protects the internal bearings from dust and coolant splashes. Because the unit is delivered without a holding brake, vertical axes must rely on an external brake or drive torque to maintain position when power is removed. The unit operates at a basic performance level, which is suitable for general-purpose motion tasks rather than highly dynamic applications. The motor uses winding code 35 for its electrical configuration, including the applicable current and torque characteristics. The module follows the standard design option and Design Version 2. It does not include integrated safety technology, so any required safety functions must be provided by external equipment.
