Product Description:

The MDD090C-N-030-N2M-130PB1 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts precisely regulated current into controlled rotary motion for industrial positioning and velocity axes. By integrating with closed-loop servo systems, the unit supports rapid direction changes and consistent speed regulation required in automated manufacturing equipment.

The servo’s nominal speed is 3000 rpm, allowing the drive to reach typical machining and transfer rates without field weakening. At standstill, it can deliver 10.4 Nm of continuous torque for controlled low-speed operation. A mechanical holding brake is fitted, and its static capacity of 6.5 Nm secures vertical or suspended axes during power-off states. Mechanical alignment to adjacent machine frames is provided by a 130 mm centering diameter. Power and feedback conductors exit on side B of the housing through a sealed connector arrangement. Position data are returned through digital servo feedback (DSF), giving the controller high-resolution rotor position for tight speed loops. A shaft seal blocks oil or coolant ingress at the output flange, protecting the internal bearings.

The housing uses standard cast aluminum and provides convection cooling without additional fins. Motor size 090 establishes the external diameter range, while length code C sets the axial dimension for compatible mounting brackets. An integrated multi-turn absolute encoder resides at the non-drive end, reporting both position and revolution count to the drive for homing-free startups. The output shaft uses a keyway and is supplied without a secondary shaft on side B, so couplings mount only on the primary face. Standard balancing further limits residual vibration during high-speed operation.
