Product Description:

The MSK100D-0300-NN-M2-BG2-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is engineered to deliver commanded torque and speed in industrial automation cells where closed-loop control and repeatable positioning are required. The size 100 stator diameter and D motor length provide a large active core, allowing the motor to move heavy tooling without an auxiliary fan. When paired with IndraDrive amplifiers, it supports dynamic cyclic duty on conveyors, presses, and pick-and-place actuators. This arrangement suits applications that combine frequent acceleration, precise stopping, and sustained torque demand during repetitive production cycles.

Heat is removed by natural convection, so the housing relies on surface area rather than a forced fan and needs clear space for rising warm air. An electrically released holding brake delivers 70 Nm of static torque to secure vertical or indexing axes when the drive is disabled. Position feedback is provided through the EnDat2.1 serial interface, and the optical transducer supplies 2048 signal periods per mechanical revolution to provide multi-turn absolute data for the controller. A plain shaft with increased concentricity minimizes runout, while the power connector on side B helps simplify wiring in tight machine frames. This combination supports accurate positioning while keeping the mechanical interface straightforward for couplings and driven elements.

The cast aluminum enclosure carries an IP65 rating that helps protect the stator windings from dust and low-pressure water jets. Its insulation system is class 155, which allows the winding to operate at elevated temperatures before thermal cutback occurs. Continuous duty is permitted within an ambient range of 0 to 40 °C, and operation outside that range requires derating. Drive tuning uses winding code 0300, which matches the motor's electrical time constants and supports predictable response during acceleration and deceleration. Increased concentricity also helps reduce velocity ripple during rapid reversals and promotes smoother running under changing loads.
