Product Description:
The MDD090C-N-040-N5L-110GB0 is identified as a Digital AC Servo motor manufactured by Rexroth Indramat. The motor belongs to the MDD line and is made for motion control. It has digital servo feedback built in and allows a shaft output that is reliable for industrial automation systems.
The MDD090C-N-040-N5L-110GB0 has a continuous torque of 10.4 Nm and a continuous current of 24.4 A. With forced cooling, the current needs go up to 33.4 A. The highest torque that can be produced theoretically is 58.6 Nm, which is the same as a peak current of 72.9 A. It is said that the torque constant at 20°C is 0.86 Nm/A, which is the same as a winding resistance of 0.34 Ohm. The 0.93 mH inductance of the windings makes sure that the current rise time stays steady. The rotational inertia of this model is 53 × 10⁻⁴ kgm². With natural convection, the thermal response time of this model is 60 minutes. It reduces to 45 minutes with forced cooling. The MDD090C-N-040-N5L-110GB0 weighs 23 kg. Between 0 and +45 °C is the temperature range for normal operation. The temperature range for keeping is from -20 °C to +80 °C, which gives you options for how to store the goods. The motor is covered by an IP65 rating, which means it is completely safe from dust and water jets. The insulation is rated as Class F, which means that it can handle safe turning temperatures. RAL 9005 black prime coat is used to cover the outside of the building.
The output shaft on the MDD090C-N-040-N5L-110GB0 AC servo motor is plain and meets standard type G requirements. The centering width is 110 mm, which makes sure that everything is lined up correctly when mounting. The power connection is on Side A. It is a digital motor feedback type that makes sure the position is controlled accurately.
Frequently Asked Questions about MDD090C-N-040-N5L-110GB0:
Q: Does MDD090C-N-040-N5L-110GB0 support forced cooling?
