Product Description:

The MST530E-0010-FT-N0SN-NNNN is a large-frame torque motor from the MST Synchronous Torque Motors series manufactured by Bosch Rexroth Indramat. As a direct-drive rotary actuator, it is intended for low-speed, high-torque duties such as indexing tables, extruders, or rotary presses where eliminating gearboxes improves accuracy and reduces maintenance. The motor uses a water-cooled, closed-circuit aluminum jacket to remove heat directly from the stator core, and its plain housing with an IP00 protection code indicates that it must be installed inside a machine frame or sealed enclosure.

The motor produces a rated torque of 2100 Nm at a rated speed of 90 rpm, which corresponds to a rated power of 19.8 kW. Achieving this output requires a rated phase current of 64 A, so the connected inverter must supply that continuous current without excessive ripple. The open aluminum cooling jacket has a diameter of 565 mm, providing enough surface area for the closed-circuit water flow to remove heat while keeping the outer dimensions compact for its torque class. No motor encoder is fitted, so position or speed feedback must be provided by an external transducer if closed-loop control is required. Electrical power and cooling connections are located on the stator end with the smaller diameter, which simplifies routing inside a cramped machine base.

For transient load peaks, the stator windings can accept a maximum current of 212 A, allowing the motor to generate up to 4700 Nm of short-term torque without thermal damage. The cooling jacket length of 210 mm matches many standard clamp collars, making mechanical integration straightforward even when axial space is limited. Overall mass is 87 kg, so the machine support must carry that static load while also handling the reaction forces produced during acceleration and braking. The cooling arrangement helps keep operating temperatures stable during changing load conditions.
