Product Description:

The MST530F-0027-FT-N0SN-D303 is a torque-optimized stator module developed by Bosch Rexroth Indramat for the MST Synchronous Torque Motors series. As a stator, it works with a matching rotor to generate high continuous torque at low speed, which makes it suitable for direct-drive rotary tables and material-forming equipment where gear reductions are undesirable. This arrangement supports precise rotary motion without the backlash and wear that can come from intermediate transmission components. Because torque is generated directly at the driven axis, the machine layout can remain compact in low-speed applications.

This unit uses liquid cooling, so the windings are cooled by circulating coolant rather than air, keeping copper temperatures within safe limits during sustained load. Power connections exit the laminated stack through axial wire leads, which simplifies routing in tight machine frames and helps keep the connection path compact. Condition monitoring is supported through a separate pair of leads sized at AWG 24; these thinner conductors carry sensing current and do not affect the main power path. Temperature feedback to the drive is supplied by a KTY84-130 silicon sensor embedded near the end turns, allowing the control system to reduce output or shut down the motor if excessive heating is detected.

Mechanical attachment is handled by a threaded bore pattern, and each mounting point uses an M10 / 23 mm deep thread that absorbs axial clamping forces without damaging the core stack. Separate thermal protection is provided by integrated 0.5 mm² safety leads that connect to an independent shutdown circuit controlled by the SNM.150.DK bimetal switch. This protective circuit operates separately from the analog temperature feedback path, giving the system a second response to abnormal heat conditions. The mounting arrangement and thermal leads support stable installation and dependable monitoring during continuous-duty operation.
