Product Description:
The MSK075E-0300-NN-S2-UP0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. It acts as a precision drive for positioning, contouring, and cyclic processes in automated production lines, transforming controlled electrical energy into accurately regulated torque and speed for machinery axes. The compact flange and standardized connector orientation simplify integration with planetary gearboxes and precision ball-screw stages. Because the motor is intended for dynamic servo applications, it can support smooth interpolation during coordinated multi-axis moves as well as stable speed control in repetitive machine cycles. Its layout is also well suited to installations that need repeatable motion in limited mounting space.
Thermal management relies on natural convection, eliminating fans and allowing a fully sealed mounting arrangement. Feedback is handled through a rotatable 240° connector that uses the EnDat2.1 protocol; together with optical scanning, it provides 2048 signal periods per mechanical turn for fine interpolation inside the drive controller. The housing meets IP65 protection, keeping dust and low-pressure water away from internal windings. Rotary power is transmitted through a shaft with keyway, which gives positive engagement with couplings and helps prevent slip under peak load. The rotatable connector also helps route cables in tight machine spaces without forcing a fixed exit direction. The motor uses frame size 075 with E length and is supplied without a holding brake, which suits axes that rely on the drive or external mechanics to hold position at standstill.
A single-turn encoder supplies absolute position data within one mechanical revolution, supporting fast reference recovery after startup. Class 155 insulation allows the windings to withstand the heat produced during frequent acceleration and deceleration cycles. The motor maintains rated accuracy in ambient temperatures from 0–40 °C, which matches typical industrial enclosure conditions. Absolute feedback within one turn is useful on axes that must re-establish position quickly after a controlled restart. Winding code 0300 identifies the electrical constant set used by compatible IndraDrive amplifiers, so current regulation and speed control remain matched to the motor.
