Product Description:

The MSK061C-0300-NN-S3-UG0-NNNN is a precision servo motor manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servo motor, it supplies regulated torque and speed for positioning axes, pick-and-place gantries, and other motion modules that require closed-loop control in industrial automation. When paired with a compatible drive, it supports smooth acceleration and accurate stopping during repetitive machine cycles. This makes it suitable for transfer, handling, and packaging equipment where repeatable motion is important across frequent starts and stops.

The motor removes heat through natural convection, so no external blower or liquid circuit is needed when it operates inside a cabinet with sufficient airflow. This cooling method keeps the housing simple and avoids the need for separate forced-air hardware. Feedback is transmitted over the Hiperface interface, allowing high-resolution position data to reach the drive controller, and the encoder connector can be rotated through 240° to simplify cable routing in tight mounting spaces. Internal measurement accuracy is supported by an encoder with 16 signal periods per revolution, and counting is handled by a capacitive scanning system that resists dust and magnetic interference. Only one mechanical revolution is tracked because the encoder is a single-turn design, making it suitable for applications that home the axis at power-up rather than relying on multi-turn memory.

The drive end uses a plain shaft, enabling direct coupling with gearboxes or pulleys without keyways that could introduce backlash. This shaft arrangement is suited to couplings that rely on clamping force rather than keyed engagement. Its frame code of 061 indicates the stator diameter and flange dimensions, while winding group 0300 corresponds to the coil inductance and rated current used with the connected inverter. This C-length variant provides a medium active stack, balancing continuous torque with installation depth. The motor uses the standard design and is delivered without a holding brake, so any load-side braking or static positioning must be handled by external mechanics or by drive torque alone.
