Product Description:

The MDD090A-N-030-N2M-110PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Created for digital drive controllers, it converts regulated current into controlled rotation for automated axes that demand consistent speed and torque. It is intended for closed-loop motion on equipment such as indexing tables, feed systems, and transfer axes where repeatable positioning is required. In these roles, the motor supports precise starts, stops, and direction changes while remaining suitable for compact machine sections.

In operation, the motor produces a continuous standstill torque of 3.7 Nm, allowing it to support static loads without thermal overload. Its rated shaft velocity reaches 3000 rpm, so commanded motion can remain synchronized with the stator field across normal operating speed. Mounting uses a centering diameter of 110 mm, which helps align the motor accurately with the machine interface. Cables exit on the right side through a single connector, which can simplify routing in compact machine layouts. Position feedback comes from an integrated multi-turn absolute encoder, so rotational position remains available after power cycling. The compact frame layout also helps the motor fit into installations with limited surrounding space.

The blocking brake delivers a holding torque of 6.5 Nm, keeping vertical or inertial loads motionless when power is removed. A dedicated shaft seal helps protect internal bearings from dust or coolant, and the output shaft uses a keyway for direct connection to keyed couplings. Motion data and diagnostics are exchanged through the digital servo feedback interface, allowing the drive to match encoder information with current commands for fast closed-loop positioning. The motor uses a standard shaft end on side A and has no side B extension, which helps keep the overall package shorter where axial space is limited.
