Product Description:

The MDD090C-N-020-N2M-110PR2 is an AC synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended to work with digital drive controllers, where commanded current is converted into controlled torque and speed for indexers, gantries, and packaging axes. The combination of a permanent-magnet rotor and encoder-based feedback supports closed-loop motion with fast reversal, accurate positioning, and stable operation in compact machine layouts. This arrangement suits automated equipment that must start, stop, and change direction repeatedly while maintaining precise shaft control.

At a nominal speed of 2000 rpm, the motor can support cycle rates commonly used in industrial automation. It provides a continuous torque of 10.4 Nm, allowing the axis to carry steady loads without overheating during prolonged operation or while holding at low speed. A spring-applied brake supplies 11.0 Nm of holding torque, so vertical or suspended axes can remain locked when input power is removed. The rotor and mounting surfaces use a standard balancing grade, which helps reduce vibration in systems with responsive servo tuning. A centering diameter of 110 mm provides the locating fit on the machine interface and helps maintain accurate alignment during installation.

Power and feedback connectors exit on the right side, which can simplify cable routing when the cabinet or cable track is positioned to the motor's left. Position data is transmitted through digital servo feedback, and absolute position retention is provided by an integrated multi-turn absolute encoder, so the connected drive can read shaft position immediately after startup. The motor also includes a shaft seal that helps keep coolant mist, dust, and other contaminants from migrating along the shaft toward internal components. This feedback arrangement allows the axis to resume commanded motion without a homing cycle after power is restored.
