Product Description:
The MSK071E-0300-NN-M3-UG0-NNNN servomotor is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is a synchronous servomotor that converts drive-controller output into precisely regulated rotary motion for positioning, indexing, and continuous-duty axes in automated machinery. The motor falls within size class 071 and length E, giving it a mid-frame footprint with elevated torque density while maintaining compatibility with standard MSK mounting geometry.
Passive thermal management relies on natural convection, eliminating fans and allowing the housing fins to dissipate heat without extra maintenance. The enclosure carries an IP65 rating, meaning dust ingress is blocked and water jets do not affect internal components, so the motor can be flange mounted outside a cabinet. Signal feedback reaches the controller through a rotatable, 240° connector that simplifies cable routing because the plug can be oriented after installation. Position data are generated by a capacitive encoder that delivers 16 signal periods per revolution, and the capacitive sensing method improves shock resistance while remaining immune to magnetic stray fields near high-current busbars.
The encoder stores position over multiple shaft revolutions through a multi-turn absolute scheme, eliminating homing sequences after power loss and supporting repeatable alignment with the drive. Because the motor is supplied without a holding brake, static load retention must be provided by drive-based torque or an external mechanical lock when needed. Continuous service is specified for ambient temperatures between 0 to 40 °C, and insulation class 155 supports winding temperatures up to 155 °C before thermal derating is necessary. The motor uses winding code 0300, which matches the stator coils to compatible IndraDrive amplifiers for the rated current and voltage of this length-E stack while maintaining the intended efficiency and dynamic response.
