Product Description:
The MSK100B-0450-NN-M2-BP0-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With its size 100 stator frame and compact B length, the unit fits medium-power axes that demand precise closed-loop motion. In an automation cell, it converts drive current into mechanical rotation so that packaging heads, gantry carriages, or tool spindles track commanded position and speed without mechanical backlash.
Thermal management is handled by natural convection, eliminating the need for forced-air or liquid cooling and simplifying mounting inside sealed cabinets. The housing carries an IP65 rating, so dust ingress and water jets do not compromise operation. A keyed output shaft, specified as a shaft with a keyway, provides positive torque transmission to gearboxes or pulleys. Feedback is supplied through an EnDat 2.1 optical encoder that delivers 2048 signal periods per revolution; when interpolated by the drive controller, this produces high position resolution for smooth velocity loops. The motor uses an increased concentricity design to minimize radial runout, and the power connector is located on the B-side to keep cabling parallel to adjacent motors and reduce bend radius.
The encoder stores position over power cycles by using a multi-turn absolute measuring system, so homing routines are unnecessary even after emergency stops. Because the rotor is supplied without a holding brake, static torque retention requires an external clamping device when the load must remain fixed. Continuous duty is supported within an ambient range of 0–40 °C, and winding code 0450 sets the electrical resistance and inductance used with the matching drive family. Class 155 insulation pairs with the convection cooling path to tolerate winding temperatures up to 155 °C without degrading varnish integrity.
