MDD090B-N-020-N2L-110PR0

MDD090B-N-020-N2L-110PR0 is a Bosch Rexroth Indramat motor in the MDD Synchronous Motors series. The motor is size 090 with length code B and has a standard housing. Its nominal speed is 2000 min⁻¹, while its continuous torque at standstill is 7.2 Nm for maintaining torque at zero speed. The maximum current is 48.6 A. At 20ºC, the torque constant is 0.86 Nm/A, indicating the torque produced per ampere. The winding resistance is 1.99 ohms at 20ºC, and the winding inductance is 10.1 mH.

Digital servo feedback (DSF) supplies position and speed information to the drive controller. The motor uses a right-facing connector for its electrical connection. Its centering diameter is 110 mm for alignment during mounting, and standard balancing supports normal rotational operation.

The shaft has a keyway for transmitting torque through a keyed connection. It uses a standard shaft end without a side B shaft end and includes a shaft seal to limit contaminant entry around the shaft. The motor has no blocking brake, so it does not mechanically hold the shaft when power is removed. Its IP65 protection category provides dust-tight protection and resistance to water jets. Class F insulation provides the motor’s electrical winding insulation, and the balancing and housing configurations are both standard.
