The R911253081 (MDD090C-N-020-N2M-130GB1) is a MDD Digital AC Servo Motor developed for integration with digital drive controllers in rapid-response automation systems. This motor utilizes electronic commutation and permanent magnet excitation, and features a plain shaft with a non-positive shaft-hub connection. It incorporates a blocking brake rated at 6.5 Nm holding torque, with a brushless, maintenance-free design and lifetime-lubricated bearings. The motor housing provides an IP65 protection rating and is finished with a coating resistant to weather, acids, and lyes. The integrated multiturn absolute encoder delivers digital servo feedback for indirect position detection. Additional technical details include a centering diameter of 130 mm, standard balancing, a continuous standstill torque of 10.4 Nm, a nominal speed of 2000 min⁻¹, and optimal operation at ambient temperatures up to 40°C and relative humidity up to 95%, at installation heights up to 1000 m above sea level. All electrical connections are provided via a connector on side B and the unit is equipped with a shaft seal.

Frequently Asked Questions

What integration advantage does the side B connector offer in reverse-wired or mirrored control panels?

The side B connector simplifies rear-facing cable routing. It supports cleaner layouts in enclosures with mirrored drives or non-standard cabinet orientations.

How does the MDD090C-N-020-N2M-130GB1 support secure load retention in vertical axis systems?

It includes a holding brake rated at 6.5 Nm. This brake locks the shaft during power-off, preventing drift or unwanted motion in suspended load applications.

Can the MDD090C-N-020-N2M-130GB1 deliver steady torque output during static hold phases in automation cycles?

It provides 10.4 Nm of continuous torque at standstill. This supports long-duration force control in press-fit or hold-position tasks without thermal derating.

How does this motor maintain shaft reference in systems requiring uninterrupted positional tracking?

An integrated multiturn absolute encoder retains absolute position across restarts. It eliminates homing requirements and improves cycle time in precision motion sequences.

What mechanical design element enhances precision alignment in rigid motor-to-load couplings?

It uses a 130 mm centering diameter for shaft alignment. This ensures concentric mounting and minimizes coupling-induced eccentricity in drive train setups.
