KSM02.1B-061C-61N-S3-HG0-ET-NN-D7-ES-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-S3-HG0-ET-NN-D7-ES-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. This device combines a servomotor, power electronics, and a fieldbus interface in one housing, allowing it to mount directly on the machine frame. It provides distributed motion control for conveyors, pick-and-place gantries, and other industrial automation axes that benefit from reduced cabinet space and simplified wiring.

It accepts a DC-link bus voltage of DC 750 V, matching the intermediate circuit used by IndraDrive power supplies, and it is part of design version 1. Heat produced by the electronics is released through natural convection, eliminating the need for fans. Power, signal, and brake conductors terminate in a single hybrid connector, which decreases assembly time and helps prevent wiring errors. Rotor position is measured through a Hiperface feedback channel, and the encoder provides 16 signal periods per mechanical revolution to support smooth velocity control. The single-turn encoder is suitable for axes that establish a reference position at power-up. Applications that require holding torque must use external clamps because the unit does not include a holding brake. The drive has a Basic performance level and does not include integrated functional safety modules.

The electromechanical stage uses frame code 061 and winding designation 61, balancing torque density with the cooling capacity available from natural convection. A plain shaft transmits torque directly to couplings or gearheads, and a shaft seal protects the motor from splash ingress. The sensing element uses capacitive technology, which is resistant to dust and magnetic interference. Multi-Ethernet master communication through the external interface allows the drive to operate as an EtherNet/IP, PROFINET, or EtherCAT node without hardware changes. The C motor length extends the magnetic stack, providing greater continuous torque than shorter motor lengths.
