Product Description:
Bosch Rexroth Indramat produces the MST160C-0050-FT-N0CN-D304 direct-drive torque motor in the MST Synchronous Torque Motors series. The unit is intended for rotary axes in automation lines where accurate positioning and high continuous torque at low rotational speed are required. By mounting the rotor directly to the load, the motor removes gear stages and minimizes compliance, making it suitable for index tables, extruders, and similar servo-controlled stations. In these roles, it acts as the primary source of motion and interfaces with modular inverter drives.
Under continuous duty, the motor operates at a rated speed of 500 rpm. At this speed, it delivers a steady output torque of 70 Nm. Multiplying these values yields a mechanical output of 3.7 kW, a figure reached while the stator draws a rated phase current of 13 A. The electromagnetic design links current to torque through a constant of 5.5 Nm/A, so the drive electronics can predict load behavior precisely. Fifteen pole pairs set the electrical frequency relationship, and a back-EMF constant of 0.42 V/rpm guides voltage scaling. Winding resistance measured at 20 °C is 3.7 Ω, contributing to the specified 2.1 kW of resistive power loss when the motor is fully loaded.
For dynamic peaks, the stator can supply a maximum phase current of 40 A, allowing the motor to reach a short-term torque of 180 Nm without loss of synchronism. The moving assembly presents a rotor inertia of 0.011 kgm², and this moderate value promotes rapid acceleration while still smoothing minor load oscillations. Corresponding masses are 4.3 kg for the rotor and 9.6 kg for the stator, which helps when assessing structural support and bearing loads. Energy storage in the magnetic circuit is influenced by a winding inductance of 15.1 mH, which limits current ripple during pulse-width modulation and supports stable servo control at low speed.
