Product Description:

The MDD090A-N-030-N5L-110PB2 is a servo motor manufactured by Bosch Rexroth Indramat. It is made to provide steady power and speed output for automated processes. The motor has a digital servo input that makes it possible to control and sync it perfectly.

The nominal speed of the MDD090A-N-030-N5L-110PB2 AC servo motor is 3000 min⁻1, which allows for stable and continuous running. At rest, the constant force is 3.7 Nm, which is kept up by a constant current of 6.3 A. It has a potential maximum torque of 17.7 Nm and can handle hard drive cycles. The highest current rating is 32.2 A, which is best for power peaks that last only a short time. A torque constant of 0.50 Nm/A at 20°C makes sure that the electrical input is converted precisely to mechanical force. The thermal time constant is 45 minutes, which shows how well the motor can handle operating heat. The MDD090A-N-030-N5L-110PB2 motor has a blocked brake with a rating of 11 Nm that keeps the load in place when the motor is turned off. The motor has a natural ventilation housing that helps keep the temperature stable. The motor has important electrical and mechanical parts that make it work with motion control systems.

With a flange diameter of Ø140 mm and a centering diameter of Ø110 mm, the MDD090A-N-030-N5L-110PB2 AC servo motor is stable to place. The diameter of the shaft is Ø19 h9, and it has a keyway for safe coupling with driven parts. The motor is in the IP65 security category, which means it is completely sealed against dust and low-pressure jets coming from all directions. Motion systems that are compact are facilitated by the motor's combined weight of 12.5 kg.

Frequently Asked Questions about MDD090A-N-030-N5L-110PB2:

Q: Does MDD090A-N-030-N5L-110PB2 include a blocking brake feature?

A: Yes, it includes an 11 Nm blocking brake. This brake holds the shaft position when the motor power is turned off.

Q: Do MDD090A-N-030-N5L-110PB2 motors use digital feedback?

A: Yes, it uses digital servo feedback. This enables accurate monitoring of motor position and enhances control precision during operation.

Q: Why does MDD090A-N-030-N5L-110PB2 need 3.1 Ohm resistance?

A: This resistance controls current flow in windings. It protects the winding system and ensures consistent motor operation under varying loads.

Q: How does MDD090A-N-030-N5L-110PB2 manage thermal load?

A: It has a 45-minute thermal time constant. This allows better heat dissipation and protects internal components from thermal stress.

Q: Why is MDD090A-N-030-N5L-110PB2 rated at 17.7 Nm?

A: This value represents the peak torque. It allows the motor to handle sudden mechanical loads during acceleration or torque spikes.
