Product Description:
The MST530G-0006-FT-N0SN-D303 is a permanent-magnet synchronous torque motor produced by Bosch Rexroth Indramat for the MST Synchronous Torque Motors series. Engineered for direct-drive applications, the unit mounts to a load without intermediate gear reduction and therefore delivers precise, backlash-free motion control in extruders, rotary tables, and winders. Its electrical and mechanical design emphasizes sustained low-speed rotation with very high moment output, supporting closed-loop servo tasks that call for accurate positioning and high continuous torque in industrial automation. Because the motor drives the load directly, it can reduce compliance in the drivetrain and support smooth motion during indexing, holding, and slow process control.
Under nominal operating conditions, the motor produces 4200 Nm of shaft torque at a synchronous speed of 60 rpm, which corresponds to a continuous mechanical output of 26.4 kW. That workload requires a phase current of 73 A, while the winding insulation tolerates pulses up to 240 A during rapid acceleration. This allows the drive system to handle short periods of increased demand while maintaining controlled motion. For overload events, the electromagnetic circuit can generate a ceiling torque of 9200 Nm without demagnetizing the rotor. Power cables use two 10.0 mm² conductors, and a separate 1.5 mm² control core carries thermal sensor and encoder signals to the drive controller.
The mechanical assembly is built for inertial stability; its rotor stores 3.84 kg·m² of kinetic energy and weighs 77 kg, while the laminated stator contributes 144 kg. This mass combination smooths speed ripple so the drive can hold tight velocity tolerance under cyclic load variations. Two 16.0 mm² connection conductors reduce resistive losses between the inverter and stator windings, and the dedicated 10.0 mm² protective earth path supports fault clearing. The separated rotor and stator masses are well suited for rigid machine structures that require stable low-speed behavior and direct torque transfer without an external gearbox.
