Product Description:
The MSK075E-0300-NN-M2-UG0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied as part of the MSK IndraDyn S Synchronous Motors series. The unit converts controlled electrical power into rotary motion for industrial axes that require precise position and speed regulation. Through its compact frame and standardized mounting interface, the motor can be paired with IndraDrive amplifiers in packaging machines, pick-and-place systems, or material-handling gantries without extensive mechanical adaptation. Because it is a synchronous design, it supports closed-loop drive control for stable speed and position under changing load conditions.
The motor dissipates heat through natural convection, eliminating external fans and simplifying cabinet design. Axis feedback comes from an optical encoder that uses the EnDat2.1 interface, and each revolution is divided into 2048 signal periods for fine angular resolution. The encoder connector can rotate 240 degrees so cables can exit in a practical direction when space is limited. A housing rating of IP65 helps keep dust and low-pressure water jets out, and the output uses a plain shaft that accepts standard clamp or friction couplings. With no separate cooling fan, there are fewer external components around the motor body, which can simplify installation in tight machine spaces. The motor is supplied without a holding brake, so an external method is needed if the load must remain fixed after power is removed.
The encoder is a multi-turn absolute device, so position data across multiple revolutions remains available after power is removed. Retained position data can reduce the need for a reference move after power cycles on suitable axes. The rotor has increased concentricity, which helps keep radial runout low and supports smooth motion in precision tooling. Permissible ambient operation spans 0 to 40 °C, and insulation class 155 allows elevated winding temperatures before derating is required. Low runout is useful where couplings, belts, or tooling benefit from smooth rotation.
