Product Description:

The MST360D-0045-FH-N0KR-NNNN is a torque motor produced by Bosch Rexroth Indramat in the MST Synchronous Torque Motors series. This direct-drive unit generates high continuous torque at low speed and is intended for rotary tables, extruders, and presses where mechanical gear stages are undesirable. By coupling the motor directly to the load, the system can reduce backlash, improve positioning accuracy, and lower maintenance demands in automated production lines. The direct-drive layout also removes belts or gearboxes that can introduce wear, compliance, or lost motion during repeated indexing cycles.

The motor's electrical operating point is based on a bus voltage of 540 V DC. At that supply level, it delivers a rated shaft output of 24.7 kW and draws a continuous phase current of 71 A. During short acceleration periods, the current can rise to 165 A, which gives the drive added torque for transient loads without changing the basic operating point. System layout must also account for a line-to-ground leakage capacitance of 14.0 nF, because this value affects the choice of RFI filters and ground-fault monitoring in the cabinet. The stator windings are routed through a right-hand terminal box, which keeps the main electrical connection grouped at one side of the machine.

Thermal management uses liquid cooling, and the coolant path is integrated as a cooling jacket in the housing so heat is removed close to the active lamination stack. This arrangement supports operation at a rated speed of 450 rpm while maintaining stable winding temperature under continuous duty. Power and feedback cables exit through the terminal box with right-side output, which helps keep cable routing organized when the motor flange faces left. No encoder is installed, so position feedback must come from an external transducer when closed-loop positioning is required. This makes the motor suitable for systems where feedback is provided elsewhere in the axis arrangement.
