Product Description:

The MSK071C-0450-NN-M1-UG1-NNNN is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. The motor is used in industrial automation to deliver precisely controlled shaft rotation for pick-and-place units, feed rollers, and other servo-driven actuators that require accurate motion. It is intended for closed-loop applications where repeatable speed and position control are important during frequent start-stop cycles. Its mechanical frame follows series conventions so it fits standardized mounting interfaces in multi-axis machines. The motor can be installed in compact axis groups where available depth is limited by guards, tooling, or transfer mechanisms.

The unit uses motor size 071 with length C, a geometry that provides moderate power density while keeping installation depth low. Cooling relies on natural convection, so no external fan or liquid circuit is required. A plain shaft transmits torque directly to the load, and the electrically released holding brake supplies 23 Nm of static torque to secure the axis when power is removed. The housing is rated IP65, which helps shield internal components from dust and water jets on the factory floor. Winding code 0450 identifies the stator's electrical setup, allowing the drive to match the intended speed-torque profile. The power and feedback connector block can be rotated 240°, simplifying cable routing inside tight enclosures. The connector can be positioned to reduce cable bend stress near the motor.

Position feedback is handled by an encoder system that combines the Hiperface digital interface with an optical scanning element. The encoder provides 128 signal periods per revolution and is configured as a multiturn absolute device, so the controller receives exact angle and revolution counts without a homing move. Continuous operation is permitted at ambient temperatures from 0–40 °C, and the windings use class 155 insulation to handle the internal heat produced during cyclic loading. Because the feedback is absolute, the control system can retain position information through power cycles. That feedback arrangement supports accurate position reporting during indexing and other servo-controlled motion.
