Product Description:

The MSK070E-0300-NN-S3-UP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor integrates into servo drive systems where rapid acceleration, repeatable positioning, and tight speed regulation are required in packaging lines, pick-and-place gantries, and general factory automation. Its electromagnetic design delivers torque proportional to current, enabling deterministic axis control through compatible Rexroth drive controllers and stable response during frequent start-stop motion.

Thermal behavior is managed by natural convection, so heat is released through the housing without fans or liquid circuits, simplifying cabinet integration. The drive end uses a shaft with a keyway, which helps prevent slip when torque is transferred to couplings, pulleys, or geared loads. The housing has an IP65 rating to resist dust ingress and low-pressure water jets in industrial areas. Position feedback is transmitted through the Hiperface protocol, and the rotatable 240° connector helps the cable exit fit confined machine spaces. Inside the encoder, capacitive electronics generate 16 signal periods per mechanical revolution, and the connected drive can interpolate that signal for precise commutation and position control.

This configuration relies on a single-turn encoder, so absolute position is available within one revolution and homing routines remain short. The winding code 0300 is matched to the size 070 stator and the longer E frame to support continuous torque output in this motor length. Safe operation is specified from 0 to 40 °C, and the insulation system is qualified for class 155 to withstand continuous winding temperatures up to 155 °C without damaging enamel or slot liners. Because the unit is supplied without a holding brake, external restraints or sustained motor torque must secure vertical or suspended loads whenever supply power is removed. This arrangement suits axes that rely on the drive system for motion control during operation but use separate load-holding measures at standstill.
