Product Description:

The MDD090A-N-020-N2M-110PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into rotary motion for positioning and speed control on automated stations. The housing suits compact machinery that requires direct coupling to gearboxes or driven loads, and the sealed stator supports installation in general-purpose industrial enclosures without additional protective covers. It is well suited for feed axes and transfer mechanisms that need accurate starts, stops, and speed changes in limited machine space.

At standstill, the motor can deliver a continuous torque of 3.7 Nm, allowing stable holding force for indexing tables and vertical axes without overheating. Under rated excitation, it reaches a nominal speed of 2000 rpm, enabling the connected drive to cover a moderate operating range before field weakening is required. Electrical power and feedback cables exit on side A through a sealed connector, which helps simplify routing when the motor is mounted in tight machine layouts. Rotor balance is classified as Standard, and an integrated multi-turn absolute encoder supplies position data over the full revolution count, eliminating the need for homing after power cycles.

The motor exchanges real-time operating data through Digital servo feedback (DSF), supporting closed-loop speed and position control without an external resolver. Mechanical alignment is aided by a centering pilot of 110 mm, which helps the flange seat accurately on the machine interface. The output shaft uses a keyway profile and includes a shaft seal that helps protect the bearing chamber from contamination while retaining lubrication. Because the unit is supplied without a blocking brake, stationary load retention must be provided by drive torque or an external holding device. Frame code 090, the A-length stator, and the absence of a side-B shaft end help keep the overall footprint compact.
