Product Description:

The MST210C-0050-FH-N0PU-NNNN is a torque motor manufactured by Bosch Rexroth Indramat and supplied within the MST Synchronous Torque Motors series. As a direct-drive component, it delivers high continuous torque at low rotational speeds, allowing gearless positioning tables, printing cylinders, and rotary indexers to couple the load directly to the shaft. In automated equipment, it replaces mechanical transmissions, improving control accuracy while the closed stator design protects the windings from process contamination.

This model is water-cooled, so the jacket circulates fluid to remove loss heat and stabilize winding temperature during continuous duty. At the nominal operating point, it produces 9.4 kW of mechanical output while turning at 750 rpm; that combination corresponds to a rated torque of 120 Nm. A phase current of 25 A is required at the terminals to hold the rated point, and the power stage must be sized for a peak demand of 100 A during acceleration. The stator is protected by a closed aluminum jacket that withstands coolant pressure and shields copper conductors from ambient moisture. Electrical energy reaches the windings through a rotatable plug connection, so cable exit can be aligned with the machine layout to ease routing and reduce strain.

For process steps that need brief speed excursions, the rotor can reach 1350 rpm, and the electromagnetic system withstands a short-term load of 250 Nm without demagnetization. Power and feedback conductors terminate on the compact RLS1200 device connector, and the drive cable must use copper conductors of 4.0 mm² to limit voltage drop and heat rise. The closed housing and direct-drive layout support use in multi-axis equipment where controlled thermal performance and compact cable routing are important.
