Product Description:
The MST530E-0010-FT-N0CN-NNL3 torque motor is manufactured by Bosch Rexroth Indramat as part of the MST Synchronous Torque Motors series. It is a high-torque stator section used in industrial automation to drive large rotary axes directly, eliminating gearboxes and improving positioning accuracy. Because the motor does not include an integrated encoder, position feedback must be provided by an external device in the machine system.
At its continuous operating point, the motor delivers a rated power of 22.00 kW. This corresponds to a rated torque of 2100 Nm while turning at a rated velocity of 100 rpm. Supplying this operating point requires a rated current of 64.0 A, and the stator-side cable is sized with a large outer diameter to carry that load. The copper windings have a resistance of 0.52 Ω and an inductance of 7.5 mH, which influence current response in the drive system. A discharge capacity of 23.0 nF provides an additional path for high-frequency currents. With 35 pole pairs, the magnetic layout is suited to very high torque at low mechanical speed. The winding zone is protected by thermal encapsulation, and liquid cooling removes heat from the stator during operation. The cooling circuit holds 1.50 L of fluid, which supports stable thermal transfer through the internal cooling ducts.
The motor can produce a maximum torque of 4700 Nm for short periods when up to a maximum current of 212.0 A is applied. The steel core contributes a moment of inertia of 1.92 kgm², which helps moderate changes in speed on large rotary axes and supports smooth acceleration behavior. The liquid circuit must maintain a flow rate of 9.5 L/min and stay below an inlet pressure of 3.0 bar to remove losses from the 63.0 kg stator. These operating limits should be observed so the cooling system can carry heat away effectively during continuous and peak-load conditions.
