Product Description:
The MSK071E-0300-NN-S2-UG0-RSNN servomotor is produced by Bosch Rexroth Indramat under the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts drive current into precisely controlled rotary motion for positioning and interpolation tasks in automated machinery. The mechanical design uses increased concentricity and integrated explosion protection to support shaft uniformity and compliance with hazardous-area requirements. This model is supplied without a holding brake, so stationary loads must be secured externally. Position feedback is generated by an optical single-turn encoder, and its rotatable 240° connector helps reduce cable strain during cabinet wiring.
With a frame size of 071 and a length code of E, this motor fits mid-range axes while still providing notable torque density. The electrical build uses winding code 0300, which corresponds to resistance and inductance values recognized by the drive electronics. Cooling is provided by natural convection, so heat leaves the stator through the housing without fans or liquid jackets. The optical feedback device provides 2048 signal periods per revolution, giving the controller fine incremental data for precise velocity and position loops. The motor uses insulation class 155, which permits winding temperatures up to 155 °C.
The motor has a protection rating of IP65, which helps keep dust and water jets away from internal components during washdown or coolant splash. Continuous operation is allowed within an ambient range of 0–40 °C, so it suits most production-floor conditions. Digital position data are transmitted through an EnDat2.1 interface, enabling bidirectional parameter exchange with the drive. A plain shaft simplifies coupling to gearboxes or pulleys and avoids keyway stress concentrations.
