Product Description:

Bosch Rexroth Indramat builds the MST530E-0014-FT-N0CN-NNNN, a stator assembly in the MST Synchronous Torque Motors series. This frameless direct-drive component is intended for rotary tables, printing cylinders, and other axes that demand high continuous torque at near-zero speed. By transmitting force directly to the load without mechanical reduction, the motor improves positioning accuracy and reduces backlash within automated machining cells and material-handling equipment. It integrates readily with liquid-cooled housings and multi-axis inverters, forming a compact torque source for synchronized motion sequences on modern production floors.

There are 20 per side holes along the stator flange, and each hole is tapped for M8 threads with a depth of 20 mm. A mounting preload of 4860 N from the magnets keeps the lamination stack seated against the machine plate during acceleration. The power and feedback bundle exits on the axial large-diameter side, preventing cable loops inside the working envelope. To control winding temperature, the copper is stabilized by thermal encapsulation and monitored by a KTY84-130 sensor that is routed on a dedicated AWG24 pair of leads. These provisions allow the drive to regulate current while the encapsulated windings dissipate heat into the host structure.

Supplementary protection is handled by the SNM.150.DK sensor, which is wired on 0.5 mm² leads and tied into the controller’s safety chain. An integrated PTC trips at 150 °C, providing an independent thermal cutoff if primary feedback is lost. The KTY element draws 2 mA and reports 1000 Ω at 100 °C, shifting linearly from 577 Ω at 25 °C, which gives the control loop ample resolution for ramp-up and stall detection. This thermal monitoring arrangement supports continuous-duty operation where the stator must hold torque at very low speed.
