Product Description:
The MSK076C-0450-NN-M1-UP1-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In frame size 076 with length code C, the unit uses the standard mechanical design and connects directly to IndraDrive power stages for closed-loop motion tasks. It supplies continuous torque for positioning tables, feeders, and forming units where precise velocity regulation and a compact installation space are required. Because it is intended for synchronous servo operation, the motor works with a matched drive to regulate torque, speed, and position in one control loop. This makes it suitable for equipment that runs frequent start-stop cycles and requires repeatable motion.
The motor dissipates heat through natural convection, so it relies on the surface area of its ribbed housing rather than auxiliary fans or coolant lines. Winding code 0450 identifies the copper section and impedance used with compatible IndraDrive amplifiers. Position feedback comes from an optical scanning system with 128 signal periods per mechanical turn, creating accurate electrical angle data for smooth commutation. These signals are transmitted over Hiperface, which allows feedback exchange and stored motor data through the same interface. The encoder data also helps the drive maintain stable motion at low speed and during rapid direction changes.
For absolute positioning across multiple revolutions, the motor uses a multi-turn absolute encoder. The feedback connection uses a 240° rotatable connector, which helps route cables in confined spaces. Torque is transferred through a shaft with keyway for positive locking between the motor and the driven load. An electrically released holding brake provides 11 Nm of static torque to hold vertical or suspended axes when power is removed. The brake is used for holding rather than dynamic stopping, so deceleration control remains with the drive. This layout supports secure standstill behavior while keeping the installation compact.
