Product Description:

The MST210E-0027-FH-N0PU-NNNN is a synchronous torque motor produced by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. As a direct-drive unit, it delivers high continuous torque at comparatively low rotational speeds, eliminating mechanical transmissions in rotary tables, extruders, and material-forming stations where smooth motion and accurate positioning are required. Because the load is coupled directly to the rotor rather than through belts or gearboxes, the axis can run with low backlash and steady motion across a low-speed operating range.

The motor has a rated speed of 700 rpm and a rated torque of 240 Nm, which results in a mechanical output of 11.00 kW. To sustain that load, the stator draws a rated current of 32.0 A, and the winding has 1.0 Ω resistance with 6.0 mH inductance. These electrical values affect current rise and drive response during torque control. A maximum electrical speed of 1100 rpm is available for short overspeed periods before the inverter reaches the voltage limit associated with the 0.700 V/rpm constant. Heat from copper losses passes into an aluminum cooling jacket integrated into the housing, so no external fan is required. Power reaches the stator through a device connector that accepts 4.0 mm² conductors, and total line-to-ground leakage capacitance is limited to 19.0 nF.

The motor can deliver up to 500 Nm during short-term peaks as long as phase current does not exceed 72.0 A. At standstill, the rotor can hold 264 Nm without cogging, which supports indexing duties and other applications that require stable static torque. The electromagnetic design provides a torque constant of 4.70 Nm/A, allowing commanded current to correspond closely to produced torque. The matching inverter must have current capability that fits both the continuous operating range and the short-term peak range of the motor.
