Product Description:

Bosch Rexroth Indramat builds the MSK075E-0300-NN-M1-UG1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. This IndraDyn S synchronous servo motor converts precision drive commands from a drive controller into exact rotary motion for positioning tables, packaging axes, and similar automation duties where closed-loop control and high dynamic response are required. The model carries the 075 frame size and E length designation, giving it a medium power envelope while keeping the overall footprint compact for cabinet or machine-frame mounting.

Thermal management relies on natural convection, so the housing dissipates heat passively without auxiliary fans or liquid circuits. Position feedback is generated by an optical encoder that uses a Hiperface interface with 128 signal periods of base resolution, allowing the drive to interpolate fine incremental positions. Because the scanning system is a multiturn absolute device, it reports rotor angle and absolute revolution count at power-up, eliminating homing moves. An electrically released brake rated at 23 Nm locks the shaft when the supply is removed, which supports vertical load axes. Its standard internal design keeps rotor inertia balanced for tight loop gains.

The enclosure carries an IP65 rating, sealing the windings from dust and low-pressure water jets so the unit can be mounted outside control cabinets. A plain shaft transmits torque without key slots, which minimizes runout when coupled with backlash-free clamping hubs. The rotatable encoder connector swivels 240° for flexible cable routing when space is restricted. Continuous duty is permitted at ambient temperatures from 0 to 40 °C, and insulation class 155 supports these temperatures without premature varnish aging. Motor designation 075E and winding code 0300 identify the electromagnetic stack used with IndraDrive controllers for mid-range torque applications.
