Product Description:
The MST210E-0027-FT-N0SN-NNNN is a frameless synchronous torque motor manufactured by Bosch Rexroth Indramat as part of the MST Synchronous Torque Motors series. Intended for direct-drive roles in industrial automation, it mounts inside machine structures and transfers drive force straight to the load, eliminating mechanical backlash that can come from couplings or gear stages. The motor’s low-speed, high-torque profile suits rotary tables, winders, and extruders that require smooth continuous rotation without external gear reduction. Because it is a frameless design, the active motor components are integrated directly into the host machine instead of being supplied in a conventional enclosed housing.
Under continuous duty, the motor delivers a rated torque of 240 Nm while maintaining a rotational speed of 330 rpm, and these values correspond to a mechanical output of 8.3 kW. At this operating point, the stator windings draw 24 A, which helps limit electrical demand during normal operation. Heat produced at rated load is removed through an integrated water cooling circuit that channels liquid through the aluminum jacket. The 195 mm jacket length provides surface area for heat exchange, and the open construction keeps weight low, although the IP00 protection code requires installation inside a sealed machine housing. This operating range is suitable for positioning and constant-speed applications that run for extended periods.
For short overloads, the design supports a maximum torque of 500 Nm at speeds up to 600 rpm. Reaching this level may require phase current as high as 90 A, so the connected drive electronics and cabling must withstand increased thermal stress during brief duty cycles. The outside diameter of the cooling jacket measures 230 mm, giving the motor a compact footprint for common stator housings while preserving space for the rotor magnet arrangement. With adequate coolant flow, the motor can handle rapid acceleration or pressing strokes during short operating intervals.
