Product Description

The Rexroth MSK050C-0450-NN-S1-UP0-NSNN is a synchronous servo motor. Synchronous servo motors are motors in which the rotor usually rotates at the same speed as the revolving field in the machine. The stator is very similar to that of an induction machine which consists of a cylindrical iron frame with windings, usually three-phase, located in slots around the inner periphery. The commissioning, operation, and maintenance should be carried out with great caution and by trained professionals. Usually, synchronous motors operate maintenance-free within the given operating conditions. However, operation under unfavorable conditions can lead to limitations in availability, thus raising the need for subsequent repairs and maintenance. Maintenance operations should be carried out within the guidelines of the manufacturer. Before working on the motor, it is essential to check with an appropriate measuring device whether parts of the system are still under residual voltage (e.g., caused by capacitors, etc.)  and be allowed to cool down before commencing maintenance. The thermal time constant stated in the technical data is a measure for the cooling time, and cooling time can be up to 140 minutes.

The MSK050C-0450-NN-S1-UP0-NSNN has a natural convection design with fan mounting. It is equipped with an integrated encoder system. To control the motor speed and/or to position the motor, the drive control device must know the current motor position.  The synchronous servo motor has a rotating power and encoder electrical connection with a shaft keyway. It is a standard design and explosion protection design without a holding brake. The winding resistance at 20 °C and the discharge capacity of the component for the MHD093B-058-PP1-RN is 3.2 Ohm and 2.4 nF, respectively. The ambient temperature during operation should be between 0 to 40 °C. The housing has an IP65 rating as per EN 60034-5 protection designation.
