Product Description:
The MSK131D-0200-NN-M1-BP1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is engineered to deliver precise torque and position control for industrial automation axes such as gantries, rotary tables, and packaging actuators. By integrating an optical encoder and an electrically released holding brake, the motor supports accurate feedback during motion and secure shaft locking when power is removed. This layout is suited to indexing axes and servo-driven mechanisms where the controller must maintain motion accuracy during acceleration, deceleration, and dwell periods.
Thermal management is handled through natural convection, eliminating the need for additional fans and simplifying enclosure design. A housing rated at IP65 protects the stator windings and bearings from dust ingress and low-pressure water jets. Position data are exchanged over the Hiperface interface, and the optical scanning system resolves the rotor angle into 128 signal periods, giving high interpolation depth for fine speed loops. The stator uses winding code 0200, which matches the motor’s electrical characteristics to compatible MSK family drives. Because cooling is passive, there are no auxiliary blowers to route around the motor body. Power cabling exits on the B-side, and the keyed shaft provides positive mechanical engagement with couplings or pulleys while helping prevent slip under load.
The electrically released brake supplies 100 Nm of holding torque, so vertical or torsion-loaded axes remain stationary during shutdowns. The encoder is a multi-turn absolute type, so absolute position tracking persists across revolutions and no homing cycle is required after power-up. Continuous operation is permitted within an ambient range of 0–40 °C, and insulation class 155 allows the windings to tolerate elevated internal temperatures without premature aging. This helps the winding system withstand repeated duty cycles in demanding motion sequences. The frame size 131 with length D provides a generous magnetic stack that supports rated torque while keeping the overall installation length compatible with common machine-frame spacing.
