Product Description:

The MSK070C-0450-NN-M1-UP1-NSNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Designed for integration with IndraDrive controllers, the unit supplies tightly regulated torque and speed for coordinated axis movement, indexing tables, and high-speed handling equipment in factory automation. Its construction conforms to both standard and explosion-protected requirements, so the same mechanical footprint can be used in general industrial zones or classified hazardous areas.

Cooling is handled through natural convection, so the stator housing dissipates thermal energy without fans or external coolant. For feedback, the motor uses a Hiperface serial interface that carries position and parameter data to the drive over a single hybrid cable. The optical scanning head resolves rotor position into 128 signal periods per revolution, and the internal encoder tracks shaft turns beyond one rotation as a multi-turn absolute value. This measurement chain relies on the optical sensing principle for repeatable position detection, and a rotatable 240° M23 connector allows the feedback plug to be aligned with cabinet or robot wrist layouts without twisting conductors.

On the mechanical side, the electrically released holding brake supplies up to 23 Nm of static torque, allowing vertical axes to remain locked when the drive is de-energized. Power is delivered through a DIN 5480 keyed output with a shaft with a keyway, which provides positive engagement with pulleys or couplings. The motor uses frame code 070, which corresponds to this housing size, and the winding code is 0450, matching drive combinations that can supply the required current density for continuous duty. Length class C completes the dimensional envelope and adds stack depth for higher thermal mass without increasing the mounting pitch.
