Product Description:
The MSK075C-0450-NN-M1-UG1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers precise torque and position control for automated machinery such as packaging gantries and material-handling axes, where electrical commands are converted into accurate rotary motion. When paired with a compatible drive, it supports controlled acceleration, stable running speed, and repeatable stopping accuracy. This makes it suitable for closed-loop applications that require consistent motion over frequent operating cycles.
The motor uses natural convection cooling, so heat is dissipated through the housing without fans. Its feedback system connects through the Hiperface digital interface, which carries absolute position data and drive parameters on a two-wire channel. Inside the optical encoder disc, 128 signal periods are produced per revolution, and drive interpolation supports fine velocity and position resolution. A spring-applied, electrically released brake delivers 23 Nm of holding torque to keep the axis locked when power is off. With a frame code of 075, the motor remains compact for medium-power applications. Optical sensing in the feedback unit helps reduce drift as operating temperature changes.
The drive interface is completed by a plain shaft that mates to zero-backlash couplings or gearheads. The encoder uses a multi-turn absolute configuration, so full rotations are counted internally and homing is not required after power is restored. Winding code 0450 indicates the electrical setup used for this motor. The mechanical length class C uses a longer stator stack to support higher continuous torque without increasing the frame diameter. The encoder connector can rotate 240°, which helps with cable routing in tight spaces.
