Product Description:
The MDD090C-N-020-N5L-130GA0 is referred to the AC servo motor from the MDD drive system. This motor is made by Rexroth Indramat. The MDD090C motor is built into industrial automation systems that need to create motion that can be controlled.
The MDD090C-N-020-N5L-130GA0 AC servo motor is capable to achieve the peak speed of 2000 min⁻1 and a standstill torque of 10.4 Nm. The power output goes up to 16.0 Nm when the cooling is better. At rest, the constant current needed is 12.1 A, but it goes up to 18.6 A when cooling is improved. It is thought that the motor can handle a high current of 72.9 A and a maximum torque of 117.6 Nm. The force stays the same at 20°C, which is 0.86 Nm per ampere. The motor's winding has a resistance of 0.64 Ohm and an inductance of 3.0 mH. It has 53 x 10⁻4 kgm² moment of inertia. The thermal time constant (Th) of this MDD motor is 60 minutes. The net weight of the MDD motor is 23 kg. It does not have a built-in blocking brake and instead uses digital servo input to control its position. The plug for the power cord is on Side L, which is the top of the case.
The MDD090C-N-020-N5L-130GA0 AC servo motor measures 405 millimeters in length. The shaft measures 19 mm in diameter and has an accuracy class of h9. The diameter of the flange is 140 mm, and the diameter of the fixing hole is 130 mm. It has four holes that are 11 mm in diameter and are spread out on a 165 mm pitch circle. It has a plain shaft type.
