Product Description:

The MST530C-0010-FT-N0RN-NNNN is a high-torque, low-speed permanent-magnet motor built by Bosch Rexroth Indramat and placed in the MST Synchronous Torque Motors series. Designed for direct integration into rotary tables, printing cylinders, or extruder screws, the unit serves as a primary drive element where precise positioning and constant torque are required without intermediary gear stages. Its frameless architecture allows direct coupling of the rotor to the load, which minimizes compliance and streamlines maintenance.

At nominal operating conditions, the motor delivers 1200 Nm of shaft torque at 100 rpm, translating to a mechanical output of 12.60 kW. The rated current drawn to reach this point is 31.2 A, supported by a winding resistance of 1.9 Ω and an inductance of 23 mH that smooths current transitions. For acceleration or disturbance rejection, the drive current may rise to 88.0 A, enabling a peak torque capability of 2700 Nm. When process requirements permit, speed can be elevated to 150 rpm while staying within thermal limits. A torque constant of 38.50 Nm/A links controller current commands to output torque, and a voltage constant of 2.810 V/min⁻¹ indicates the back EMF that the inverter must accommodate.

Heat generated in the copper windings is removed through liquid cooling, ensuring continuous operation without derating. Structural stability is reinforced by thermo-encapsulation, which locks the coils in place and shields them from environmental stress. Power exits the housing through a radial cable sized for a conductor area of 6.0 mm², which helps keep resistive losses low at the stated currents. Position feedback hardware is omitted, so the motor is supplied without a motor encoder, allowing the machine designer to select an external sensor or use sensorless torque control as needed.
