Product Description:

The MSK050B-0450-NN-S1-UP0-NSNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated equipment, it converts drive current into controlled rotary motion for indexing tables, gantry axes, precision fillers, and similar servo-driven mechanisms. Its compact form supports installation in machine sections where space is limited but accurate torque and speed control are still required. The synchronous design helps the connected drive respond quickly to command changes during acceleration, deceleration, and repeated positioning moves. This type of motor is commonly used where repeatable motion quality is more important than simple open-loop rotation. When paired with a compatible amplifier, the motor supports closed-loop axis control in packaging, handling, and processing equipment.

The motor uses natural convection, so air must circulate around the housing to carry away heat during normal operation. Position feedback is provided by a single-turn encoder over the Hiperface interface, and the encoder produces 128 signal periods per revolution for control of speed and rotor angle. Its connector can rotate through 240°, which helps when the cable must enter from a restricted direction or pass through a narrow bend area. Because the sensor is optical, position detection does not rely on magnetic sensing elements near the motor. The housing has an IP65 rating to resist dust and low-pressure water jets in industrial environments.

The output end uses a shaft with keyway, allowing secure torque transfer to couplings, pulleys, and other fitted transmission parts. The servomotor is intended for ambient temperatures from 0 to 40 °C, which suits many enclosed machines and general factory spaces. Its insulation class is 155, allowing the winding system to tolerate elevated internal temperatures during repeated load changes. Because the motor is supplied without a holding brake, a parked or vertical load must be secured by external mechanics or controlled drive torque. That arrangement is common in machines that already use a separate brake or locking device on the axis. The keyed shaft arrangement also helps limit slip between the motor and the driven element when a matched hub is installed.
