Product Description:

The MSK071E-0300-FN-M2-UG0-RNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it supplies precise torque and velocity control for axis drives in machining centers, packaging lines, and other automated equipment. The designation 071 indicates the frame size, while the winding code 0300 and length code E tailor its electromagnetic profile for medium-torque applications. By converting regulated current from a servo drive into controlled rotary motion, the motor supports closed-loop positioning, repeatable speed control, and responsive acceleration in automated machinery.

Thermal management relies on Liquid cooling, allowing continuous heat removal from the stator windings and helping the motor sustain rated output during demanding duty cycles. The housing has an IP65 protection rating, which keeps out dust and resists water jets in typical industrial environments. Rated operation is permitted in ambient temperatures from 0 to 40 °C. Feedback is handled through an EnDat2.1 optical encoder that delivers 2048 signal periods per revolution. The encoder uses Multiturn Absolute feedback, so position data across 4096 turns remains available after power loss, which helps the axis return to controlled motion without repeating its reference process. The motor is supplied without a holding brake, so static loads must be secured by external clamping or by drive-generated torque.

Mechanical alignment benefits from the increased concentricity build, which reduces radial runout at the coupling interface and supports smooth rotation at the driven element. Service access is improved by a rotatable 240° feedback plug, so the cable can exit in several directions without retermination when mounting space is limited. Power is transmitted by a plain shaft, which suits clamp-style hubs that require a direct, backlash-free connection. Class 155 insulation supports winding durability during continuous duty and repeated thermal loading.
