Product Description:

The MSK070E-0150-NN-M1-UG1-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for use in motion-controlled production cells, pick-and-place stations, and packaging axes. As a member of the MSK IndraDyn S Synchronous Motors series, it converts commanded current from a compatible drive into precise rotary motion for positioning and speed control. That operating profile suits transfer systems, indexing mechanisms, and coordinated handling axes that require repeatable starts, stops, and speed changes during short machine cycles. Motor size 070 with the E-length housing gives the unit a compact format suited to medium-torque axes.

This motor rejects heat to the ambient air through natural convection, so no external blower or liquid circuit is required. The electrically released brake develops 23 Nm of static torque to secure the shaft during power-off or emergency-stop conditions. Position feedback is generated by an optical encoder that communicates over the Hiperface protocol. The scale delivers 128 signal periods per revolution, and its multiturn absolute design stores complete revolutions so the axis can resume without a homing move after a power loss. Optical scanning provides fine edge definition, allowing the controller to interpolate for high-resolution velocity loops.

The output uses a plain shaft, which simplifies coupling arrangements and avoids a keyed profile at the drive end. The stator uses winding code 0150, matching compatible drives for the required current and voltage range. For flexible cabinet layouts, the encoder plug is rotatable through 240°, reducing strain on feedback cabling when cable runs must turn around guards or support members. The plain shaft layout also works well with clamp-style hubs and other friction-based couplings used on compact servo axes. The standard enclosure supports installation in machines where forced ventilation is impractical.
