Product Description:

The MSK071D-0450-FN-M1-UG0-NNNN is an AC synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Built for closed-loop motion tasks in industrial automation, it converts drive current into precisely regulated mechanical power for positioning axes, pick-and-place gantries, and packaging modules. It is intended for servo axes that require accurate position tracking and repeatable speed control during frequent starts, stops, and direction changes. A standard design housing bolts directly to servo gear units or machine frames.

Heat generated by the windings is extracted through liquid cooling, allowing the size 071, length D frame to maintain continuous torque without external fan units. The encoder connector is rotatable, 240°, so cable exit can be aligned inside crowded cabinets while preserving sealing integrity. Position feedback travels over Hiperface, providing digital identification and sine-cosine tracks for high-bandwidth control. Internal sensing relies on an optical scanning assembly that reduces electrical noise in harsh environments. Because the encoder is multiturn absolute, the drive retains position information over many mechanical revolutions even after power cycles, which helps the axis return to operation without a reference run.

The feedback disk divides each mechanical turn into 128 signal periods, giving the controller fine angular resolution for tight velocity loops. For stopping duties, the motor is supplied without a holding brake, so static load retention must be provided by the drive or external mechanics. A plain shaft interface supports backlash-free clamp couplings, which are commonly used where accurate concentricity is important. The balanced rotor matches the factory-set 0450 winding code, which corresponds to the stator's voltage constant and rated current. This arrangement suits motion systems that rely on precise coupling alignment and external holding methods during standstill.
