Product Description:

The MSK070C-0300-NN-M1-UP0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Intended for use in precise industrial automation, this motor forms the mechanical end of an IndraDrive axis and supplies controllable torque and speed to conveyors, pick-and-place units, or tooling heads. Its format complies with IndraDyn family designations, giving machine builders a consistent footprint and cabling scheme when selecting motors across different continuous power ratings.

Heat dissipation relies on natural convection, so the housing must be mounted where ambient airflow can remove losses without forced fans. Position feedback is handled by a Hiperface interface that supplies digital absolute data to the drive over a bidirectional serial channel. Within the encoder, 128 signal periods per mechanical revolution are interpolated for fine velocity control. The sensing element uses optical scanning, providing low jitter at high speeds. Mechanical energy is delivered through a shaft with a keyway, allowing positive torque transfer to pulleys or couplings while maintaining axial alignment.

The feedback connector is rotatable through 240°, so the cable exit can be oriented away from machine obstacles without violating bend-radius limits. Internal gearing inside the encoder counts complete turns, delivering multi-turn absolute position data and eliminating homing routines after power loss. The motor has a size 070 frame, and the active stack uses length code C to fit narrow axis frames. Electrical properties follow winding code 0300, which tells the drive which current and voltage maps to use for torque production. The motor is supplied without a holding brake, so it is suited to applications that rely on drive torque or external stoppers to maintain position during shutdown.
