Product Description:

The MSK071E-0303-FN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop axis control in industrial automation where precise torque and speed regulation are required for packaging machinery, gantry systems, or tool handling equipment. Its synchronous design supports smooth acceleration and accurate positioning across repeated machine cycles. The motor is shipped without a holding brake, so static load retention must be handled by mechanical locking devices or continuous drive torque when the machine is at rest.

This motor removes heat through liquid cooling, so continuous output can be sustained when it is mounted inside compact machine frames. The encoder connector is rotatable through 240°, allowing cable routing to be aligned with the cabinet layout while avoiding strain on the plug. Position feedback is exchanged through a Hiperface interface, giving digital bidirectional communication between the encoder and the drive. Inside the encoder, one revolution is subdivided into 128 signal periods, which supports stable velocity loops at low speeds. The housing carries an IP65 rating, which blocks dust ingress and resists low-pressure water jets during washdown cleaning.

The optical feedback unit tracks multiple turns with a Multiturn Absolute design, so the controller knows rotor position immediately after power-up without a homing move. Operation is specified from 0 to 40 °C, which suits typical control cabinet conditions in standard plant environments. A plain shaft simplifies coupling to precision gearboxes or integrated pinions where keyways are unnecessary. The winding insulation system is classified for 155 °C, enabling reliable thermal endurance during cyclic loads. This arrangement supports continuous servo operation where compact mounting and stable thermal performance are both important.
