MSK076C-0450-NN-M1-UG1-NSNN

The MSK076C-0450-NN-M1-UG1-NSNN synchronous servomotor is manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for precise velocity and position control in industrial automation, supplying direct drive torque to machine axes without intermediate gearing. The motor integrates standard feedback and power connectors so that commissioning with Rexroth drive controllers is straightforward. A reinforced housing and optional explosion-protected variant allow installation in production environments that impose both dynamic motion demands and rigorous safety requirements.

Mechanical dimensions are set by the motor size code 076 and the length code C, delivering a mid-range frame that balances inertia and continuous torque. Heat is removed through Natural convection, eliminating the need for forced-air accessories and reducing maintenance points. The rotor is coupled to the load through a plain shaft for backlash-free transmission. Feedback signals are supplied via a rotatable 240° encoder connector that simplifies cable routing in tight cabinets. Position data is transmitted over the Hiperface interface, and fine resolution of 128 signal periods supports smooth interpolation at the drive. Together these parameters define the motor’s electrical matching and mechanical envelope.

The winding code 0450 characterizes the stator geometry and establishes the current and voltage values expected by the drive amplifier. An electrically-released holding brake supplies 11 Nm of static torque to secure vertical or suspended loads during power-off events. The feedback device uses Multiturn Absolute counting, so the axis retains absolute position across power cycles without homing moves, and its Optical scanning principle delivers low drift over temperature. This combination simplifies commissioning while allowing safe, repeatable operation in coordinated multi-axis systems.
