R911286360
The R911286360 (MDD115A-N-030-N2M-180GA1), created by Bosch Rexroth Indramat, is a synchronous, permanent-magnet servo motor with electronic commutation. Falling under the standard balance class, it has a centering diameter of 180mm. It's part of the MDD115 AC digital intelligent drive control system, and it is essential to only operate it with specified Rexroth modules. For optimal function, ensure it is damage-free during installation. This component's handling and start-up should be under the supervision of a trained professional. Connection to an A-side power connector supplies its operational voltage. Additionally, it houses a 24 VDC brake to produce a 45 Nm blocking torque.
The model R911286360 (MDD115A-N-030-N2M-180GA1) operates best in temperatures from 0 to +45 degrees Celsius without derating, while the highest allowable temperature is +55 degrees Celsius with a 20% performance reduction. It relies on natural convection and surface cooling to equilibrium its temperature. Weighing in at 33 kg, it uses a constant current of 42.4 A to yield a continuous torque of 28 Nm at a speed of 3000 rpm. At an ambient 20 degrees Celsius, the motor winding resistance is 0.13 Ohms. Furthermore, standard bearing allows for high radial loads, and a DSF-integrated multiturn absolute encoder supports accurate positioning.
