MSK071C-0450-NN-M2-UP0-RNNN

The MSK071C-0450-NN-M2-UP0-RNNN is a synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts drive inverter power into controlled rotary motion for positioning tables, packaging spindles, and handling axes. The motor sits in the mid-power range and matches 400 V class power stages. A rigid output shaft lets the device combine electrical precision with secure torque transfer in compact servo modules common in gantry systems.

Cooling relies on natural convection, so external fans are not required. The encoder connector is rotatable, 240°, permitting cable exits to align with machine contours. Position data travels over EnDat2.1, a bidirectional serial link. An optical scale generates 2048 signal periods each revolution; internal multiplication by the drive yields fine speed and angle resolution. These features limit following error during rapid indexing and allow compact routing inside multi-axis cabinets in dense machine frames.

The encoder stores multiple turns as a multiturn absolute value, eliminating power-up homing routines. The motor is supplied without a holding brake, which lowers rotor inertia for high acceleration moves; clamping must therefore be handled externally if needed. Torque is delivered through a shaft with keyway compatible with standard keyed couplings. Electrically, winding code 0450 sets the resistance and inductance for constant-torque operation with MSK drives. Bosch Rexroth applies increased concentricity tolerances, minimizing run-out and keeping the air gap uniform. The combination of motor length C and the 071 frame produces a compact mid-power unit suited to direct-drive or gear-coupled packaging, printing, and assembly machinery in light automation cells and robotics.
