Product Description:
The MSK071D-0450-NN-S1-UP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It delivers closed-loop speed and position control for automation equipment such as pick-and-place modules, printing cylinders, and material-handling gantries. By combining a high-resolution optical encoder with a permanently excited rotor, the unit converts drive commands into precise rotary motion that supports fast, deterministic production cycles. Its motor design also supports stable torque production across a broad operating range, which helps maintain accurate axis behavior when load conditions change during normal machine movement.
Heat is removed solely through natural convection, eliminating external fan wiring and simplifying airflow around the motor. The housing follows the standard design format and matches length code D, so it fits easily on medium-depth machine frames. A feedback connector that is rotatable through 240° allows flexible cable routing around nearby panels and brackets without forcing a sharp bend at the connection point. Position data move to the controller over the Hiperface serial channel, and the optical sensor generates 128 signal periods per revolution for smooth interpolation and steady low-speed motion. This arrangement helps the drive maintain precise feedback transmission while keeping the installation layout compact and easy to route.
An electrically released holding brake supplies 23 Nm of static torque, securing vertical or offset loads during power loss. The encoder uses a single-turn format, providing absolute position within one mechanical turn without the added complexity of multi-turn gearing. Power is transmitted through a shaft with a keyway, making the motor compatible with standard pulleys and hub clamps. Electromagnetic behavior follows winding code 0450, which sets the phase resistance and current constants used by mid-range IndraDrive amplifiers. The frame size 071 gives the motor a compact footprint for general-purpose machine axes where space is limited but responsive servo performance is still required.
