Product Description:

Bosch Rexroth Indramat manufactures the MST360B-0018-FH-N0KR-NNNN, a synchronous torque motor within the MST Synchronous Torque Motors series. The part is supplied as a stator section that mounts directly into an application’s mechanical frame and interfaces with a separate rotor. It is designed for industrial automation tasks that demand slow, smooth rotation with high torque, allowing gearboxes to be omitted in extruders, winding stations, and indexers. An aluminum cooling jacket surrounds the stator housing, and water circulates through that jacket to remove heat generated during continuous duty.

At its continuous operating point, the motor delivers a shaft speed of 180 rpm while producing 375 Nm of torque, yielding an output of 7.10 kW. To reach this point, the windings draw 20.0 A, and each ampere contributes approximately 18.80 Nm/A because of the torque constant measured at 20 °C. The stator contains 25 pole pairs, and its copper circuits present a winding resistance of 2.43 Ω, which influences power loss and thermal load. Water cooling is mandatory, with a required flow of 4.0 L/min through the right-side terminal box feed. The aluminum cooling jacket keeps operating temperature stable while permitting the motor to hold its rated figures during continuous production.

When higher load steps occur, the magnetic circuit can generate up to 900 Nm of peak torque, and it resists motion at standstill with 440 Nm. The design limits electrical speed to 330 rpm, matching applications that need precise positioning rather than high rotational speed. Dynamic current modulation is influenced by the phase inductance of 19.2 mH, which filters switching harmonics from the drive amplifier. Installation considerations include the stator mass of 37.0 kg, requiring suitable handling equipment and secure brackets. Short overload events are supported when the cooling circuit is operating correctly.
