Product Description:

The MDD090A-N-020-N2L-130GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers electronically commutated torque that supports precise motion on automated tooling, packaging, and assembly stations. An A-length stator in the 090 frame provides a compact envelope for space-limited machine layouts. The motor is suited for applications that require repeatable speed control and accurate positioning during continuous industrial operation.

Its centering pilot measures 130 mm, allowing accurate concentric alignment between the motor flange and adjoining mechanics so radial runout stays within tolerance. At standstill, the rotor can sustain 3.7 Nm of continuous torque, giving holding force for vertical axes without overheating the windings. During operation, the rated shaft speed reaches 2000 rpm, balancing moderate velocity with the motor’s thermal capacity. Electrical power, resolver, and brake lines leave the housing on the left side, and a plug-in connector provides a clean electrical interface. Standard balancing keeps residual vibration low, while the standard housing casting supports natural convection cooling in ambient machine enclosures.

Position accuracy is delivered through digital servo feedback (DSF), which returns high-resolution rotor data to the drive for closed-loop control. The output interface uses a plain shaft, and the model is supplied without a side-B shaft extension on the rear face. A lip seal surrounds the journal, providing operation with a shaft seal so lubricants cannot migrate into the stator area. Because the design is supplied without a blocking brake, external holding force or drive torque is required when power is removed.
