Product Description:
The MSK100B-0450-NN-M2-AG2-RNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. As a torque source for CNC tables, pick-and-place axes, and material-handling spindles, it converts drive-controller commands into controlled rotary motion during indexing, feeding, and positioning tasks. Its multi-turn optical encoder reports absolute shaft position for closed-loop control, so the connected drive can track angle and speed without relying on an external feedback device. An electrically released holding brake is integrated to keep the load fixed when system power is removed, which helps prevent unwanted axis movement during stops or power loss.
This model is cooled by natural convection, so heat is dissipated through the outer housing without auxiliary blowers or liquid lines. A housing tightness rating of IP65 blocks dust ingress and water jets, allowing direct mounting inside production cells where the motor is exposed to normal industrial contamination. The brake can hold up to 70 Nm of static torque, which helps resist back-driving on vertical axes and other applications with stored mechanical energy. Position feedback comes from an optical system with 2048 signal periods per revolution, giving the drive fine resolution for speed regulation and positioning tasks. The feedback channel uses the EnDat2.1 interface for bidirectional communication, so operating data and position information can pass through the same digital link.
The motor operates in ambient air from 0 to 40 °C without derating, which suits typical shop floor conditions. Its windings use insulation class 155, allowing the insulation system to withstand elevated temperatures during cyclic loading. The mechanical frame code is 100, placing the motor in a housing size suited to medium-duty servo axes that need stable running and accurate shaft alignment. Winding code 0450 identifies the electrical winding arrangement used with the connected inverter, matching current and voltage behavior to the motor's torque characteristics.
