Product Description:
The MSK070E-0150-NN-M1-UG0-NNNN servo unit is built by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It converts drive-controller current into controlled torque and speed for indexing tables, pick-and-place heads, and other positioning axes used in industrial automation. The size 070 motor with length class E gives a balanced combination of torque capability, compact installation dimensions, and inertia suitable for direct mounting on machine assemblies. Its standard mechanical layout also supports straightforward alignment with common couplings and flange interfaces used in modular equipment.
Heat is removed by natural convection, so the housing fins must remain exposed to ambient airflow and no forced-air or liquid circuit is required. Motion feedback is provided through an optical encoder with 128 signal periods per revolution, and the multiturn absolute function preserves position information after a power interruption across multiple shaft revolutions. The encoder communicates over the Hiperface interface through a rotatable 240-degree connector, which helps with cable routing in tight enclosures. The motor has a plain shaft, so torque is transferred through clamp couplings or shrink discs rather than keyed hubs, which helps reduce backlash. It is supplied without a holding brake, so any static load retention must be handled by external machine components or by controlled drive torque.
The enclosure carries an IP65 rating, which helps protect the internal windings against dust and low-pressure water jets during normal machine operation. Continuous operation is permitted in ambient temperatures from 0 to 40 °C, and insulation class 155 allows elevated internal temperatures without premature aging of varnish or lead insulation. Stator winding code 0150 identifies the winding arrangement used with matching IndraDrive amplifiers. These characteristics support stable thermal behavior, reliable encoder communication, and repeatable motion in automated assembly and handling systems.
