MRT290D-3N-0200-NNNN

Product Description:

The MRT290D-3N-0200-NNNN is a highly dynamic rotor released and pioneered by Rexroth Indramat under the famous IndraDyn T product series. Featuring a stable construction and thermally stable surface, this rotor performs well for heavy driving tasks requiring an output torque of more than 350 Nm. Specifically, this rotor model has a total mass of 9 kilograms and a moment of inertia of 0.11 kg(m^2). For rotors, the moment of inertia indicates the amount of rotational force needed to accelerate along the main axis. The larger the moment of inertia, the harder it is to make the rotor accelerate or rotate along its main axis. Considering the size and torque capabilities of the MRT290D-3N-0200-NNNN, its moment of inertia is impressively low.

Rexroth Bosch designed the MRT290D-3N-0200-NNNN for MST stators having the same frame class. Specifically, stators under the MST290D-XXXX-F product line are all compatible with the MRT290D-3N-0200-NNNN. Depending on the stator, this rotor model can achieve different nameplate speed, maximum speed, nameplate current, maximum current, rated torque, and maximum torque. For instance, with an MST290D-0002-F stator, the MRT290D-3N-0200-NNNN can deliver a nameplate torque and velocity of 350 Nm and 25 Nm, respectively. On the other hand, when paired with an MST290D-0018-F stator, this rotor can achieve a velocity and torque output of 180 rpm and 350 Nm, accordingly.

Regardless of the stator model, this MRT290D-3N-0200-NNNN has a thermal time constant of 3.3 minutes. During operation, this rotor model benefits from the integrated liquid cooling system on the stator. Since the stator is more susceptible to overheating, especially on its windings, the cooling system and sensors are usually placed on the stator. Rotors, on the other hand, facilitate cooling via convection.
