Product Description:

The MRT360B-3N-0260-NNNN is a synchronous torque motor component manufactured by Bosch Rexroth Indramat within the MRT Synchronous IndraDyn T Motors series. It serves as the rotary drive element in direct-drive positioning or indexing tasks where mechanical transmissions are eliminated and torque is produced directly at the load. When integrated into machine frames, this motor supports precise, low-speed motion control that is often required in assembly systems, printing presses, and similar automation cells.

Its axial stack measures 120 mm, a dimension that sets the active magnetic length and directly influences continuous torque output. The clear inner opening of 260 mm allows cables, pipes, or shafts to pass through the motor bore while keeping the overall assembly compact. An external stator circle of 385 mm sets the mounting envelope and determines the available surface area for thermal transfer. With an enclosure classification of IP00, all active parts must be built into a protected housing, which allows flexible cooling arrangements. The maximum speed rating of 1700 rpm indicates the highest permitted rotational speed before magnetic forces, temperature rise, or bearing selection may limit service life.

This unit is supplied in the Standard design version, so it does not include special winding or cooling modifications. Mechanical coupling to the load side is handled through a screw attachment, so the rotor can be rigidly fixed to a hub or flange without adhesives. Dynamic behavior is characterized by a rotor inertia of 0.194 kg·m², which balances acceleration capability against torsional stability when large torques are commanded. The rotor mass of 9.8 kg must be considered in support-structure calculations so bearings, frames, and lifting equipment are sized correctly during installation.
