Product Description:

Bosch Rexroth Indramat manufactures the MSK070D-0300-NN-M1-UG1-NSNN in the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servomotor converts electrical energy into controlled mechanical rotation for positioning, conveying, and similar automation tasks. When paired with a compatible drive controller, it delivers controlled torque and speed for industrial axes that require compact dimensions, sealed construction, and integrated feedback. Its compact format makes it suitable for machine sections where installation space is limited but precise motion is still required.

Heat is dissipated by natural convection, so no external fan is required when the motor operates within its rated load. The aluminum housing has an IP65 rating that helps block dust ingress and withstand water jets on machine frames. An electrically released holding brake rated at 23 Nm secures the shaft during power loss, which is useful on vertical axes or other applications that need holding force at standstill. Position data is exchanged through the Hiperface interface, and the optical scale provides 128 signal periods per revolution for closed-loop commutation. Approval for standard and explosion-protected zones broadens the range of suitable installations, and the 070 frame size offers a practical balance of torque density and installation space.

The encoder uses a multi-turn absolute design, so position remains available across multiple revolutions and homing after every power cycle is not required. Its connector allows 240° rotation, which helps with cable routing where clearance is tight. Continuous operation is permitted from 0–40 °C, and Class 155 insulation supports reliable winding operation at elevated temperatures. The optical sensing principle supports accurate feedback without magnetic components, while the D length, plain shaft, and winding code 0300 match the motor’s intended mechanical and electrical configuration.
