MDD090A-N-030-N2M-110PB1
The MDD090A-N-030-N2M-110PB1, a synchronous motor by Bosch Rexroth Indramat, is part of the MDD series notable for their high power-to-weight ratio and synchronous operation. It has low inertia due to the use of iron oxide and rare earth materials in its rotor’s permanent magnets, lending it a torque-inertia ratio that optimizes high dynamics. This brushless design has lifetime-lubricated bearings accommodating high radial loads, facilitating direct mounting of pinions and belt pulleys. Additionally, it includes thermal sensors to avert overload damage. The motor supports a high cyclic load capacity, optimal for start-stop operations that require high repetition rates. Its nominal speed registers at 3,000 RPM and its rotor's moment of inertia is 20 x 10-4 kgm2. The motor utilizes digital servo feedback with an integrated multiturn absolute encoder for precise position detection. Furthermore, it features a blocking brake with a 6.5Nm torque for secure holding of the servo axis in a power-off condition.
