Product Description:

The MDD090A-N-030-N2M-110GB2 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical commands from the drive into controlled mechanical rotation for automated axes in production lines. Its compact 090 frame size and standard housing support use in packaging, material handling, and general machine tool assemblies. This layout suits equipment that needs accurate speed and position control without a large motor body.

Mechanical interface details start with a centering diameter of 110 mm, allowing precise pilot alignment to gearboxes or mounting flanges. Power and feedback cables exit on side B through a keyed connector, which helps keep cable routing organized. Once energized, the rotor can develop 3.7 Nm of continuous torque at standstill for closed-loop holding duty. Position data is captured by an integrated multiturn absolute encoder, allowing the drive to track shaft position after power cycles. For passive stopping or power loss, a blocking brake applies 11.0 Nm of static torque. Standard dynamic balancing limits vibration during high-speed operation, and the sealed housing helps keep contaminants away from internal parts.

Control integration relies on digital servo feedback, so the drive can process position information without analog conversion. The motor uses length code A, which keeps overall mass low while preserving the compact dimensions of this frame. Under rated voltage, the rotor reaches 3000 rpm, giving the axis a useful operating range for rapid positioning moves. The output interface is a plain shaft with a shaft seal, which supports direct coupling while helping block coolant or oil migration along the journal. Because the shaft is not extended on the rear, the standard shaft-end arrangement simplifies coupling to pinions or flexible couplers.
