Product Description:

The MDD090A-N-030-N2M-130GA1 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, converting inverter output into controlled mechanical rotation for positioning tables, pick-and-place axes, or feeder modules. Its synchronous design supports precise torque and speed regulation during repeated starts, stops, and short indexing moves. Basic rotor balancing and a standard housing are included, and the sealed shaft end helps limit contaminant ingress in typical factory environments.

The motor can deliver a continuous standstill torque of 3.7 Nm, providing steady force while the axis remains energized at zero speed. At rated excitation, the rotor reaches 3000 rpm, supporting high-speed automation duty where short cycle times are important. Mechanical alignment during installation is assisted by a 130 mm centering diameter that matches standard Indramat flange patterns, which helps the motor seat accurately against the machine interface. Power and feedback conductors exit on side A, which can simplify cable routing when the connected harness must stay clear of moving tooling or linear guides. A keyed circular connector is preinstalled, allowing direct connection to matching drive cables and reducing the chance of misalignment at the interface.

A holding brake rated at 6.5 Nm locks the shaft when power is removed, helping prevent back-driving on vertical or suspended loads. Rotor position and revolution count are detected by an integrated multi-turn absolute encoder, so the controller retains position information after power cycles. The digital servo feedback interface provides high-resolution data for closed-loop control and stable motion response. Motion is transferred through a plain shaft with an integrated shaft seal, which helps reduce lubricant migration from the gearbox into the motor interior. This shaft arrangement also avoids the stress concentration associated with keyed transmission on applications that use clamp-style couplings.
