Product Description:

The MSK076C-0450-NN-M1-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S unit, it supplies tightly controlled torque and velocity for positioning axes in industrial automation and machine-tool equipment. The motor includes an integrated encoder for absolute position monitoring and is built for direct coupling to Rexroth drive controllers where precise speed regulation and a compact form factor are priorities. It fulfills drive tasks that require high dynamic response while maintaining passive cooling.

The motor uses natural convection as its cooling method, so ambient airflow alone removes the copper and stator heat generated during rated operation. The encoder connector is rotatable 240°, allowing flexible cable exit without twisting conductors inside tight cabinets. Position data are exchanged over the Hiperface interface, and this bidirectional protocol carries absolute position and parameter information between the motor and the controller. Inside the encoder, an optical scanning head resolves 128 signal periods, and because the measuring unit is multiturn absolute, the drive retains true mechanical position across up to 4096 revolutions even after power loss. The motor does not include a holding brake, which reduces mass and eliminates brake-release wiring when the application already uses static gearing or external clamps.

The motor has frame size 076 and length code C, giving a stator stack suited to mid-range torque demands while keeping the envelope width compatible with compact gearboxes. A plain shaft is supplied, so torque is transmitted through press-fit couplings or external key hubs rather than an integral keyway. The motor uses winding code 0450, which indicates the number of turns and conductor cross-section used in the stator slots to match standard MSK drive output voltages and currents.
