The MRT Synchronous IndraDyn T Motors from Bosch Rexroth are synchronous torque motors supplied as rotor and stator components intended for direct integration into a machine, with the installation, handling, and lifecycle steps (from delivery through disposal) covered for fitters, operators, and service personnel.
They support different thermal concepts, including natural convection and liquid cooling, and stators can be supplied without a housing for machine-built connection technology or with a housing that provides dedicated coolant connection ports. For liquid-cooled configurations, the documentation specifies practical integration requirements such as verifying and venting the cooling circuit, monitoring flow/pressure/temperature, and observing a maximum coolant supply pressure of 6 bar at the motor connection while avoiding flow restrictions from tubing or fittings. The series includes motor protection and sensing provisions, including a required temperature-sensing connection to the drive controller for thermal overload protection and guidance for coolant in/out routing for vertical installation. Mechanically, the manual emphasizes that mounting hardware and fastening practices must account for the motor’s high torque capability, and it highlights handling precautions due to strong magnetic forces around the rotor during assembly to prevent injury or component damage.
