Product Description:

The MST530C-0010-FH-N0KR-NNNN torque motor is produced by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. This frameless rotary actuator is intended for direct-drive tables, extruders, and winding stations on automation lines where high continuous torque at low speed eliminates mechanical gearboxes. It handles position and speed control tasks while an integrated cooling jacket and liquid circuit maintain temperature stability during extended duty cycles. Because the motor is built for direct coupling, it can reduce backlash and mechanical wear that would otherwise come from intermediate transmission components.

The motor delivers a continuous output of 1200 Nm at its nominal shaft rate of 100 rpm, which is the rated operating point under the specified coolant flow. Electrical input at this condition is limited to a phase current of 31.2 A, and a torque constant of 38.50 Nm/A converts that current into the stated mechanical output. When the application demands short bursts, the winding can accept up to 88.0 A, allowing a peak torque capability of 2700 Nm. The maximum speed is 150 rpm, which suits low-speed rotary tables and drums that are driven without intermediate reduction, and the short-term current reserve supports brief acceleration or load changes.

The electrical design includes a winding resistance of 1.9 Ω and an inductance of 23 mH, and both values influence current response and voltage demand in the connected drive. Thermal management relies on liquid cooling circulated through a jacket integrated into the housing, keeping losses at or below the rated mechanical power of 12.60 kW. Installation uses a right-hand cable exit with a smaller-diameter conduit, and the power leads terminate on conductors sized 6.0 mm² to support the required current path. The motor body weighs 84.0 kg, so the supporting structure must carry substantial mass while still allowing access to coolant connections and direct attachment to the driven axis.
