Product Description:
The MST161C-0140-FT-N0CN-NNNN is a member of Bosch Rexroth Indramat’s MST Synchronous Torque Motors series. This direct-drive torque motor is intended for indexing tables, rotary fillers, and other automation stations that demand high torque at moderate speed without intermediate gear reduction. By mounting the rotor directly to the load, the unit reduces backlash and maintenance while providing precise position control in closed-loop drive systems. That arrangement also improves response in rotary axes where fast reversals and accurate holding are required.
At its continuous operating point, the motor delivers 52.0 Nm of torque while turning at 1400 rpm; these two parameters describe the rated mechanical output that can be sustained without exceeding temperature limits monitored by the embedded sensors. Electrical input at that point is 17.4 A, producing 7.60 kW of shaft power, so the selected drive and cabling must support that current. The stator is wound with ten pole pairs, enabling smooth detent-free motion even at single-digit revolutions per minute and giving the controller finer electrical resolution. This helps the servo loop maintain smooth rotation during low-speed indexing and fine angular corrections. For the main power leads, copper conductors with a 2.5 mm² cross-section are used to keep resistive losses within limits. A voltage constant of 0.204 V/rpm links rotational speed to the back EMF that the inverter must overcome during regeneration.
For dynamic peaks, the rotor can generate 160 Nm, and when held motionless it resists load with 65 Nm of standstill torque. The electromagnetic conversion factor is 3.25 Nm/A, giving predictable open-loop torque estimates for drive control. Transient current changes are filtered by a winding inductance of 10.6 mH, while copper losses are set by a winding resistance of 2.0 ohms at 20 °C. The motor reaches 1900 rpm electrically, but sustained overloads are limited by a 2.0-minute thermal time constant. Liquid cooling is required; a 2.0 L/min flow at a maximum inlet pressure of 6.0 bar keeps the stator within its permitted temperature rise during continuous cyclic duty. The liquid circuit removes heat more effectively than passive cooling when the axis repeats short, high-torque moves.
