Product Description:

The MSK070E-0300-NN-M3-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In factory automation, the unit converts controlled electrical power from an IndraDrive into precise rotary motion for positioning axes, packaging machinery, and handling systems. The motor’s compact 070 frame and E-length stator design provide a middle-range torque class while maintaining compatibility with standard Rexroth drives and cables. Its output end can couple directly to gearheads or bellows couplings without additional axial fixtures.

Heat generated by the windings is dissipated by natural convection, so cabinet airflow must be sufficient to keep the housing within its rated limits during continuous duty. An IP65 protection rating seals the stator housing and connector zone against dust ingress and water jets, allowing installation on open machine frames without secondary enclosures. Position feedback is exchanged through a Hiperface serial interface, giving a single-cable digital link to the drive. Inside the encoder module, rotor angle is detected with capacitive scanning rather than optical discs, which improves immunity to oil mist and vibration. A plain shaft output eliminates key slots, reducing imbalance and permitting shrink-fit couplings.

The multiturn sensor provides a base angular resolution of 16 signal periods per mechanical revolution and stores up to 4096 revolutions of absolute position; this is indicated by the Multiturn Absolute designation in the encoder data. Electromagnetic characteristics are set by Winding Code 0300, a coil set matched to typical drive currents found in medium line-voltage installations. Thermal endurance follows insulation class 155, permitting winding temperatures up to 155 °C during peak cycles. The motor operates within a 0–40 °C ambient range and is built without a holding brake, so external holding force is required when the axis must remain fixed after power is removed.
