Product Description:

The MDD090C-N-020-N2L-110GB1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, the device pairs with regulated power stages to deliver controlled torque and speed in assembly stations, packing equipment, and material-handling axes. The size 090 housing and C-length stator give the motor a compact footprint that fits standardized machine frames. This layout supports responsive motion in automated equipment where repeatable acceleration and accurate position control are required. In closed-loop operation, the matched controller can adjust current quickly as load conditions change.

The mechanical interface is centered on a 110 mm pilot, which helps align the motor flange with the driven assembly. Electrical and feedback conductors exit on Side B, a layout that simplifies cable routing when the drive is mounted behind the machine plate. A sealed industrial connector carries both power and feedback lines, which keeps the connection arrangement compact and simplifies service access. With rated cooling, the rotor can deliver a continuous standstill torque of 10.4 Nm, providing a clear limit for stationary load holding at zero speed. During motion, the winding supports stable operation up to 2000 rpm. This speed suits common gearbox ratios and feed rates used in servo-controlled processes.

A permanent-magnet holding brake rated for 6.5 Nm is integrated to maintain axis position when power is removed. This is useful on vertical axes and indexing tables that must remain in place between moves. Position data is returned through digital servo feedback (DSF), allowing the controller to close high-resolution loops without a separate external encoder. The rotor is dynamically balanced to the standard grade, and the smooth plain shaft is fitted with a shaft seal to help keep contaminants away from internal components. This shaft arrangement supports direct coupling to hubs or clamping elements in clean, enclosed machine installations.
