Product Description:
Bosch Rexroth Indramat manufactures the MDD090C-N-030-N2L-110GR0 synchronous motor within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, where it receives controlled pulse-width-modulated power from an inverter and develops mechanical rotation for positioning tables, transfer belts, or tool drives in automated equipment. The design targets installations that need compact servo power at medium speed while allowing direct integration into closed-loop motion systems used on factory floors. Its synchronous operating principle helps the shaft follow commanded speed changes with predictable response. When paired with a compatible servo amplifier, the motor supports accurate acceleration and repeatable positioning during cyclic machine movement.
Mechanical alignment begins with a centering diameter of 110 mm, allowing the flange to seat squarely against gearboxes or machine frames. The rotor can deliver a continuous standstill torque of 10.4 Nm, helping the axis resist load movement without excessive heating. Under drive excitation, the unit reaches a nominal speed of 3000 rpm, matching the operating range of standard Indramat inverters. Position and velocity data are returned through digital servo feedback (DSF), which the controller samples for real-time commutation and closed-loop correction. Power and feedback leads attach through a sealed connector interface, and all connections are oriented on the right side to simplify cable routing. The 090 frame size and C length code place the motor in a compact housing suited to medium-duty servo axes.
The motor body uses a standard housing, and the rotating assembly uses standard balancing to limit residual vibration at higher speed. Motion is transferred by a plain shaft, and a shaft seal around the journal helps block dust and oil ingress. Because the unit is supplied without a blocking brake, any vertical or safety-critical axis requires an external holding method when power is removed. The motor has a single shaft end and no side B extension, which preserves rear clearance for the right-side connectors. This layout also leaves space around the cable entry area and keeps the overall installation depth compact.
