Product Description:
The MRT210T-3N-0140-ST02 belongs to the MRT Synchronous IndraDyn T Motors series produced by Bosch Rexroth Indramat. This frameless torque motor stator is intended for direct-drive rotary tables, printing drums, and indexing actuators in industrial automation systems. Its direct-drive configuration eliminates mechanical transmission components that could introduce backlash between the motor and the load. This arrangement supports accurate positioning and responsive motion during repetitive production cycles.
The electromagnetic design places the rotor opposite the stator across a small air gap, generating an axial attraction of 195 N that must be accommodated by the bearing set. A radial attraction of 830 N also influences the required bearing preload and support arrangement. The stator flange has 12 fixing holes, allowing clamping force to be distributed evenly around its circumference. Mechanical coupling on the rotor side uses an M6 fixing thread, which is suitable for precision faceplate fixtures. The permitted thread depth is 14 mm, establishing the maximum screw engagement without contact with internal components. The selected lamination and magnetic materials provide thermal stability during brief overload conditions without permanent loss of magnetic flux.
The stator windings tolerate limited field-weakening periods, while a demagnetization hold time of 30 min indicates how long the magnets can remain at the residual temperature without falling below their rated polarity. The maximum demagnetization temperature is 300 °C, providing an upper limit for short-term thermal excursions during emergency stops or stalled-rotor conditions. The balanced mounting arrangement helps prevent uneven mechanical stress around the stator flange during operation. Available stack-height options allow selection of a suitable torque constant while preserving compatible mechanical interfaces within the motor platform.
