Product Description:

The MSK071E-0300-NN-M2-UP2-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as the rotary drive element in automated stations that require accurate speed regulation and closed-loop torque control. When paired with IndraDrive converters, it provides high-resolution feedback and controlled acceleration for pick-and-place modules, packaging tables, and other motion platforms.

Cooling for this motor is handled by natural convection, a passive method that relies on ambient airflow and therefore limits the continuous load. The mechanical design features increased concentricity, which helps reduce radial runout where tight coupling accuracy is necessary. Service access is aided by a motor-side encoder plug that is rotatable through 240°, allowing the cable exit to be positioned without straining the conductors. Position data travels over an EnDat 2.1 serial interface, so the controller receives digital feedback without additional conversion hardware. Inside the encoder, the scanning disk provides 2048 signal periods per revolution, giving the drive a base signal for interpolation.

The sensing assembly uses optical scanning for high signal fidelity, and its multiturn absolute architecture retains position across full revolutions for startup without homing. For safety during power loss, the motor carries an electrically released brake rated at 30 Nm, which helps hold vertical axes without external clamps. Mechanical coupling is performed through a shaft with a keyway, while the 071 frame size and E-length housing maintain compatibility with standard MSK mounting patterns. The 0300 winding code matches the unit with drive sections that provide the proper current density, and operation must remain within the limits of passive cooling.
