Product Description:
The MSK070D-0450-NN-M1-UG1-NNNN servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servo motor, it converts regulated AC power from compatible drive controllers into precise rotary motion for packaging lines, pick-and-place robots, printing cylinders, and general machine-tool axes. It is intended for closed-loop motion tasks that require accurate speed control, repeatable positioning, and smooth response during frequent start-stop cycles. The D-length construction allows a higher stack height than shorter variants, which increases continuous torque within the same frame diameter.
The motor uses natural convection for heat dissipation, so installation must leave clearance around the housing and no external fan is required. Its encoder connector is rotatable through 240°, letting the cable outlet be aligned toward the cabinet without twisting the cable. Position feedback is exchanged through the Hiperface interface, and the encoder provides 128 signal periods per revolution for interpolation in the drive. Electrical parameters follow winding code 0450, which corresponds to coil resistance and inductance suited to medium-torque, medium-speed duty. The standard mechanical layout uses a plain shaft that couples directly with clamping hubs or other friction-fit connections.
An optical scanning element inside the encoder helps maintain low jitter, and the multiturn absolute design retains the actual shaft position across 4,096 mechanical turns. That arrangement allows position information to remain available after power-up without a homing move. For static load holding, the electrically released brake supplies 23 Nm of counter-torque, allowing vertical or safety-critical axes to remain locked when the drive is disabled. The size code 070 corresponds to a housing diameter near 82 mm, letting the motor fit compact machinery without sacrificing continuous performance. All bearings are lubricated for the full maintenance-free interval provided for this motor.
