Product Description:
The MSK071C-0450-NN-M1-UP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Classified as a standard-design unit, it converts electrical energy into precisely regulated mechanical torque for automated machine axes that need repeatable position and velocity control. Its synchronous design allows the drive to regulate torque, speed, and position with a predictable response during repetitive motion cycles. When paired with compatible IndraDrive controllers, the motor fits tasks such as pick-and-place stages, gantries, and packaging lines where closed-loop feedback and compact mechanics are preferred.
Heat is removed solely through natural convection, so no external blower or liquid circuit is required. An electrically released holding brake secures stationary loads with 23 Nm of static torque when power is off. The output side uses a shaft with a keyway, allowing direct coupling with keyed hubs without relying on shrink fits. This arrangement supports keyed couplings without requiring a separate shaft adapter. Rotor position is transmitted over the Hiperface serial interface, and one mechanical revolution is resolved into 128 signal periods for commutation and speed control. The motor follows size code 071 and carries the C length variant to balance torque density against housing depth.
The feedback hardware is housed in a connector that is rotatable through 240°, enabling cable routing to be directed away from nearby obstacles during installation. Absolute position data across multiple turns is stored by a multi-turn absolute optical scanner, while the same photodiode array supports single-turn interpolation through an optical sensing method and avoids the wear associated with magnetic resolvers. Electrical data matches winding code 0450, a winding variant selected for voltage and current characteristics compatible with mid-range IndraDrive amplifiers. This combination supports accurate feedback handling while keeping the motor suitable for compact axis layouts.
