Product Description:

The MSK071D-0300-NN-M1-UP0-NNBN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machining centers, pick-and-place gantries, and packaging stations, it converts electrical energy from a drive controller into tightly regulated torque and speed for precise axis positioning and repeatable cycle times. Its standardized mechanical and electrical interfaces support integration into modular drive systems, and it is suited for feed axes, transfer units, and other applications that require responsive motion with stable control behavior.

Heat is removed through natural convection, so additional fans or liquid circuits are not required when the ambient temperature stays within the permitted range. A rotatable 240° connector carries the Hiperface protocol, combining sensor power and bidirectional data lines in one connection. The encoder subdivides one mechanical revolution into 128 signal periods, and interpolation in the drive increases position resolution for motion control. Because the sensing chain is optical and multiturn absolute, the controller can read the true position across multiple turns after power is restored. The enclosure meets IP65, which helps protect internal components from dust and water jets. This feedback arrangement supports accurate speed regulation and stable position tracking during both short indexing moves and continuous motion profiles.

The drivetrain interface uses a shaft with keyway, which provides positive torque transmission to pulleys or gearboxes during rapid reversals. The keyed shaft arrangement also supports couplings that require secure mechanical engagement under changing loads. The motor has no integrated brake, so holding force at standstill must be supplied by external mechanics or an energized servo loop. Continuous duty is permitted from 0 to 40 °C, which suits many enclosed industrial installations. The insulation system is rated at 155, allowing the winding to operate at elevated temperatures within its class limits. Winding code 0300 identifies the electrical winding setup used by the inverter for current control and commutation.
