Product Description:

The MST210S-0024-FT-N0CN-D302 is a stator package from the MST Synchronous Torque Motors series manufactured by Bosch Rexroth Indramat. It is intended for direct-drive installations where high torque is required at low speed without mechanical reduction stages. When combined with a matching rotor and inverter, the stator forms the electromagnetic core of a rotary axis used in indexing tables, plastic extrusion screws, or roll drives within automated production lines.

This model uses liquid cooling, so coolant channels inside the housing extract heat continuously and help keep copper temperatures stable during sustained torque output. The housing is equipped with separate power and sensor cable glands that isolate high-current conductors from feedback wiring. Power leads are routed through a gland sized for cables with an outer diameter of 9.8 ±0.3 mm, while sensor leads pass through a second gland that fits 6.0 ±0.2 mm jackets. Both the installed and required supply conductors are 1.5 mm², which simplifies cable selection and keeps the wiring consistent across the drive chain. All terminations exit on the stator end with a large outside-diameter connection flange. Because the stator is supplied without an internal encoder, the machine builder must mount an external feedback device on the driven shaft.

Twelve evenly spaced mounting holes surround the stator’s inner circumference, and the hole count is 12. Each hole is tapped for an M5 screw with a thread depth of 10 mm, and all holes open toward the cable output side to simplify bolt insertion during service. Coil assemblies are locked in place with thermo-encapsulation, a resin process that resists vibration and helps prevent moisture ingress. A dedicated sensor cable with 1.0 mm² conductors carries temperature signals from embedded detectors to the drive controller, allowing the cooling loop to respond quickly to thermal load changes.
