Product Description:
The MRT290E-3N-0200-NNNN is one of Bosch Indramat’s most stable rotors under the IndraDyn T product line. Boasting a perfectly balanced construction and high-quality materials, this rotor can meet the demands of the heaviest loads. Depending on the stator, the MRT290E-3N-0200-NNNN can achieve different synchronous speeds. When used with an MST290E-0004-F stator, this rotor can run at a rated speed of 40 Nm up to a maximum velocity of 130 Nm. Using the same MSS stator, this rotor can deliver a nameplate torque of 575 Nm and a maximum torque of 1150 Nm. Weighing about 11.6 kilograms without the stator, this rotor is suitable for delivering high torque output at relatively low speeds.
Considering its massive size and sturdy construction, the MRT290E-3N-0200-NNNN requires a greater amount of excitation to reach its steady-state speed. The amount of force required to accelerate rotors is described by the rotor’s moment of inertia. For MRT290E-XX-0200 rotors, the moment of inertia is equal to 0.17 kg(m^2). Based on its type code, the MRT290E-3N-0200-NNNN employs a set of screws for its mounting system. It employs a standard design and has an internal rotor radius of 100 millimeters. As mentioned earlier, this rotor is designed by Rexroth Bosch for MST290E stators in mind. Usually, MST stators come with a set of temperature sensors for aiding their cooling system.
As a massive rotor unit from the IndraDyn T series, the MRT290E-3N-0200-NNNN boasts high radial and axial loading limits. For rotors, the radial force limit dictates the maximum magnitude of force that can act tangentially on the rotor. On the other hand, the axial loading limit determines the maximum force magnitude that can act parallel to the shaft’s main axis. Based on its datasheet, the MRT290E-3N-0200-NNNN has radial and axial force limits of 2490 N and 289 N, respectively.
