Product Description:

The MSK071E-0300-NN-M1-AP2-NNAN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In industrial automation, it converts controlled drive current into rotational motion for positioning tables, pick-and-place axes, and gantry modules that demand precise torque and speed regulation. The motor is intended for dynamic axis control, where repeatable motion and fast response are needed through changing loads and short machine cycles. When paired with a compatible servo drive, it supports accurate speed changes, controlled acceleration, and stable positioning during repeated production cycles. A reduced runout mechanical design also helps limit radial error during rotation.

The stator winding uses code 0300, and the motor has frame size 071 with length E, which indicates its electromagnetic and mechanical size. Cooling is handled by natural convection, so performance assumes free airflow rather than forced ventilation. Power enters through the A-side connector, which keeps cable access on one face of the machine frame. Position feedback comes from an optical encoder that uses Hiperface communication with 128 signal periods per revolution and multi-turn absolute position memory, allowing the drive to restore shaft position after power loss. This feedback system supports closed-loop control without relying on an external measuring device mounted on the load. Motion is secured by an electrically released holding brake that provides 30 Nm of static torque, which helps hold the axis at rest without external clamps.

The housing carries an IP65 rating, which helps protect the interior against dust and directed water jets. The windings use insulation class 155 and are intended for an ambient temperature range of 0 to 40 °C. Torque is transmitted through a shaft with keyway, which provides positive engagement for couplings, belts, or geared stages. This keyed interface can simplify mounting where a friction-fit shaft is not preferred. It is also useful on axes that transmit torque through keyed hubs or pulleys.
