Product Description:

The MDD090A-N-030-N2M-130GR1 is a synchronous servo motor built by Bosch Rexroth Indramat for use with digital drive controllers in automated machinery. It belongs to the MDD Synchronous Motors series and uses size 090 with short length A, giving the motor a compact format for medium-inertia loads. Standard dynamic balancing helps reduce vibration during high-speed operation. Its compact frame suits machine axes that need responsive motion without the larger footprint of a longer housing. As a motor for digital drive controllers, it converts commanded current into regulated mechanical motion for positioning and speed-controlled axes in assembly lines, packaging stations, and similar equipment.

A machined pilot with a centering diameter of 130 mm aligns the flange to gearboxes or machine frames. Power, feedback, and brake lines enter through a connector on the right side, which helps cable routing in compact machine spaces. The rotor can deliver 3.7 Nm of continuous torque at standstill, and the blocking brake provides 6.5 Nm of static holding torque to resist back-driving forces. Under rated excitation, the shaft reaches a nominal speed of 3000 rpm. A standard aluminum housing helps dissipate heat during normal operation.

Position data comes from an integrated multiturn absolute encoder. The drive processes this signal through digital servo feedback (DSF) so closed-loop control can remain accurate during rapid cycles and repeated direction changes. This feedback arrangement also lets the control system retain absolute position information over multiple revolutions. The output uses a plain shaft with a shaft seal, and the standard shaft arrangement omits a second shaft end on side B to keep the axial length compact. The shaft seal helps limit lubricant migration at the coupling end while also reducing the entry of fine dust.
