Product Description:

The MSK075E-0200-NN-M2-UP1-RNNN is an AC synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It acts as the rotary element in automated packaging lines, gantry stages, robotic joints, and other servo-driven machinery, converting electrical drive commands into controlled torque and position. By integrating a high-resolution optical encoder with a low-cogging magnetic circuit, the unit supports precise closed-loop control where rapid positioning and consistent velocity profiles are mandatory.

The motor’s housing is designated size 075, while the active stack is length code E; these dimensions set the mounting footprint and continuous thermal capacity of the motor. Electromagnetic behavior is characterized by winding code 0200, allowing the paired drive to set current limits without manual scaling. Cooling relies on natural convection, so free air circulation across the finned stator surface is required to dissipate losses. Output torque is delivered through a shaft with a keyway, giving positive mechanical engagement to couplings and helping avoid slippage during frequent start-stop cycles and rapid reversals.

Production accuracy is supported by an increased concentricity design and a multiturn optical encoder. Communication with the controller is handled via the EnDat2.1 interface, and the readhead provides 2048 signal periods per revolution for fine interpolation. The encoder connector can rotate 240°, easing cable management inside compact enclosures. When power is removed, an electrically released brake holds the rotor with 23 Nm of torque, ensuring safe retention of suspended loads. Careful mechanical balancing helps reduce vibration during continuous motion and repeated acceleration cycles, which supports stable operation across changing speed commands.
