Product Description:
The MSK101E-0300-NN-S2-AG2-RNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In an automation cell, it accepts regulated current from an IndraDrive amplifier and produces precise, repeatable shaft rotation that positions tooling, conveyors, or rotary tables at programmed coordinates. This supports accurate motion on packaging, handling, and indexing equipment where repeatable positioning is required throughout cyclic operation. By integrating an optical single-turn encoder, an electrically released holding brake, and a sealed housing in one unit, the motor simplifies axis construction.
The mechanical footprint uses motor size 101, while length code E indicates the active lamination stack used for continuous torque output. Winding code 0300 sets the electrical constants so the connected controller can apply the correct voltage and current limits. Heat produced in those windings is removed by natural convection, so the housing must remain exposed to ambient air. A protection rating of IP65 seals the stator against dust ingress and low-pressure water jets, allowing installation adjacent to washdown zones. With its power connector on the A-side, cables can exit in a common direction with other field wiring, reducing bend-radius conflicts and easing cable routing.
The electrically released brake supplies 70 Nm of static holding torque to secure vertical or indexed loads when power is removed. Position data are reported through an EnDat2.1 serial interface, and each revolution is subdivided into 2048 signal periods for closed-loop interpolation at the drive. Continuous service is supported within an ambient range of 0–40 °C; above this range, the drive must derate motor current to protect the Class 155 insulation system. A plain shaft transmits torque without keyway stress concentrations, and the increased concentricity design keeps radial runout low so couplings or timing pulleys mount with less correction during alignment.
