Product Description:

The MSK043C-0600-NN-S1-UP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit is intended for position and speed control tasks in automated machinery where compact dimensions and precise feedback are required. It combines a frame size 043 stator with length code C in a standard design that can be mounted directly in packaging, material-handling, or pick-and-place modules. In typical servo applications, the motor converts controlled current into rotary motion for indexing, transfer, and synchronized axis movement. An integral optical encoder passes position data to the drive, allowing closed-loop regulation during fast duty cycles.

In operation, the motor dissipates heat by natural convection, so airflow around the housing must remain unobstructed to keep winding temperatures within the range associated with winding code 0600. Position feedback is delivered through an optical measuring system, and the connector is rotatable through 240° to simplify cable routing while communicating over Hiperface. The optical scanner divides one mechanical revolution into 128 signal periods, and because the device is single-turn, it reports the absolute shaft angle within one revolution. This feedback arrangement gives the controller the rotor position information needed for accurate commutation and stable speed regulation. A shaft with keyway transmits torque to the load, and the standard construction supports compact installation where space around the motor is limited.

Mechanical holding torque is provided by an electrically released brake rated at 4 Nm, allowing the axis to remain fixed during power interruptions. The brake is useful on axes that must stay in place when drive power is removed. The cast-aluminum enclosure carries an IP65 rating, sealing the stator against dust and water jets so the motor can be mounted near process equipment. Continuous service is specified from 0 to 40 °C, aligning with the insulation capability of Class 155 materials to limit thermal aging. This operating range suits enclosed machine sections where repeatable motion is required without external cooling hardware.
