Product Description:

The MST360B-0018-FT-N0SN-NNNN is a low-speed, high-torque motor in the MST Synchronous Torque Motors series from Bosch Rexroth Indramat. As a frameless stator intended for direct-drive tables or rotary axes, the unit converts electrical energy into continuous turning force at process speeds without intermediate gearing. By integrating directly into machine structures, it simplifies layouts and maintains precise angular control essential for large indexing tables, winders, and similar automation tasks. This direct-drive arrangement also helps reduce backlash and compliance that can occur in mechanical transmission stages.

At its nominal operating point, the stator develops 375 Nm of continuous torque while maintaining a shaft rate of 180 rpm; the mechanical power associated with these conditions is 7.1 kW. Supplying that output requires a phase current of 20 A drawn through three windings arranged in a balanced three-phase configuration. Thermal management is handled by an aluminum cooling jacket that circulates process fluid in a closed loop, and the forced convection provided by liquid cooling helps keep the copper below its thermal limit during extended duty cycles. Electrical leads exit on the stator side with a smaller outside diameter so the assembly can fit more easily into confined housings.

When short bursts of force are required, the winding can accept peaks up to 900 Nm and a momentary line current of 70 A without exceeding permissible insulation temperatures. The stator mass of 23 kg gives the assembly enough thermal inertia to buffer these transient loads while remaining manageable for integration into larger rotary systems. Thermal encapsulation surrounds the coils to protect them from vibration and moisture ingress, and the absence of a motor encoder leaves the feedback device to be selected separately for the application. That separation can support motion systems that require a feedback device chosen to match the accuracy and control architecture of the axis.
