Product Description:

The MSK071E-0450-NN-S1-UP0-NNNN is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. Within an automation cell, it converts drive current into precise rotary motion, allowing closed-loop positioning and speed regulation for packaging stations, material-handling axes, and similar duties. It is used where accurate shaft movement is required over repeated cycles. The motor pairs directly with compatible IndraDrive controllers and feedback devices used across the same platform.

The unit removes internal heat solely by natural convection, so its mounting location must permit ambient air to pass over the housing. It uses a standard mechanical design, so no special coating or reinforced bearings are included. The feedback plug is a rotatable 240° connector, letting the cable exit be oriented after installation. Position data travel over the Hiperface interface, and the sensor provides 128 signal periods per revolution through an optical scanning process. Because the encoder is a single-turn model, it resolves absolute position within one mechanical turn and relies on the drive to track additional turns. Motor length code E indicates the stator stack height used for this power rating, so axial space must match that length.

Frame size 071 gives the flange and shaft geometry used by this motor. Torque is transmitted by a shaft with keyway, which supports couplings and pulleys that require positive mechanical engagement. The winding designation 0450 identifies the electrical characteristics expected by the matching drive. This version is delivered without a holding brake, so the load must be secured by the machine or by drive-applied torque when power is removed. The motor is intended for synchronous servo operation where quick response and repeatable positioning are required.
