Product Description:

The MDD112C-N-020-N2L-180GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies controlled torque and speed to axes that require precise closed-loop positioning. Its mechanical outline follows the 112 size frame, and length code C indicates the stator stack depth used for mid-range continuous output. Standard housing construction, standard dynamic balancing, and a centering pilot help the motor align accurately with the machine flange during installation. This arrangement suits automation equipment that depends on steady motion response during repeated indexing, positioning, and speed changes.

The motor’s centering diameter measures 180 mm, allowing a rigid fit to large gearboxes or direct-drive couplings. At standstill, it can deliver a continuous torque of 28.0 Nm, so static loads can be supported while thermal limits remain under drive supervision. When energized at rated frequency, it reaches a nominal speed of 2000 rpm, which fits many servo applications that need a balance of torque and rotational speed. Position information is returned through digital servo feedback, allowing the controller to maintain commutation and accurate position tracking without an external feedback device. A plain shaft transmits torque without keyways, which reduces local stress concentrations and supports accurate coupling alignment.

Power and feedback conductors exit on side A through a single connector, which keeps the electrical interface compact and simplifies cable routing. The unit is supplied without a blocking brake, so holding force at standstill must come from the drive or from external mechanical hardware. A shaft seal is fitted at the output end to help limit lubricant migration and reduce the entry of contaminants near the bearing area. There is no shaft extension on side B, so torque is transmitted only through the primary output side. The cable outlet direction can also be useful where the motor is mounted close to guards, frames, or adjacent drive components.
