Product Description:
Bosch Rexroth Indramat made the MDD090A-N-020-N2G-110PB1 which is referred to the digital AC servo motor. It is part of the MDD line, which is commonly used in motion control. The precision of closed-loop control is improved by the digital servo input of the product. Consistently adapting to temperature fluctuations in a variety of circumstances is guaranteed by the motor's natural convection cover.
The MDD090A-N-020-N2G-110PB1 has a maximum speed of 2000 revolutions per minute. At rest, it gives off a steady 3.7 Nm of torque and consumes 4.2 A of constant current. The motor can produce up to 17.7 Nm of torque, which needs up to 32.2 A of current. It possesses a torque constant of 0.88 Nm per ampere at 20°C. The rotor's moment of inertia is 20 × 10⁻ kg·m², which makes it easy to speed up and slow down while it is moving. The windings' 4.0 Ohm resistance and 12.4 μ inductance affect the current's rising time and performance. It takes 45 minutes for the thermal time constant to reflect how the heater behaves during load cycles. The output shaft is made with a keyway that meets DIN 6885-A 8×7·40 standards. This allows for a safe mechanical connection. On side B of the motor is a power connector, and on side 1, there is a straight feedback connection that makes wiring easier.
The MDD090A-N-020-N2G-110PB1 motor has a centering diameter of Ø110 mm, which lets align motors steadily with mounting connections that work with it. The motor is made to meet the needs of automation systems that need precise servo movements. The motor has a blocking brake that makes it safer to use and better holds loads in vertical axis systems. The stopping brake has a torque of 6.5 Nm that keeps the position even when the system is turned off.
Frequently Asked Questions about MDD090A-N-020-N2G-110PB1:
Q: How does MDD090A-N-020-N2G-110PB1 ensure thermal stability?
A: The thermal time constant of 45 minutes enables gradual heating. It protects windings during extended duty cycles.
