Product Description:

The MSK071C-0450-NN-M2-UP0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It supplies precise torque and speed control to automated machinery, acting as the rotating element of a closed-loop drive system. The motor couples directly to a gearbox or load and returns high-resolution position data, enabling coordinated multi-axis movement in production cells.

Heat is removed by natural convection, so no external fan or liquid circuit is needed because the housing surface disperses the losses generated by the stator winding. An enclosure rating of IP65 seals the stator against dust ingress and low-pressure water jets, allowing mounting outside a cabinet when the application requires it. For feedback, the motor integrates an optical encoder that communicates through the EnDat2.1 serial interface. The encoder provides 2048 signal periods, and because it is a multiturn absolute design, it tracks shaft position over multiple revolutions without battery support. This feedback gives the controller fine incremental data together with absolute position information during operation.

The motor uses a shaft with a keyway, while the rotor is balanced with increased concentricity to minimize runout at higher speeds. The winding code 0450 sets the electrical constants used by compatible IndraDrive amplifiers. Thermal integrity is supported by insulation class 155 and an operating range of 0 to 40 °C, allowing continuous duty in most control rooms. Because the unit is supplied without a holding brake, any power-off load securing must be handled by external mechanics or the drive’s torque mode. A rotatable 240° encoder connector eases cable routing, and the size 071, length C frame keeps the overall package compact for line-side installation.
