Product Description:

The MDD090A-N-030-N2L-110GL0 is a synchronous motor assembled by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts commanded current into rotary motion for automated machinery such as pick-and-place axes, packaging arms, and indexing stations. The unit works with drive modules that supervise current, speed, and position in closed-loop operation, allowing coordinated multi-axis motion from a common bus without mechanical gearing. This arrangement supports repeatable starts, reversals, and stopping behavior during automated cycles. It is suited to applications that need smooth speed control and consistent position response throughout repeated production sequences.

Mechanical integration starts with the centering pilot of 110 mm, which aligns the flange to the machine frame while standard balancing helps limit residual vibration during high-speed service. Power and feedback conductors exit on the Left side, and a sealed connector block allows cabinet wiring without hard soldering. The rotor uses a plain shaft for a keyless coupling, and a shaft seal helps protect the internal bearings from coolant spray. Position data is returned through Digital servo feedback (DSF), enabling accurate rotor-angle monitoring for closed-loop motion. The housing dissipates heat by natural convection, and the shaft is provided only on side A to keep the overall length compact.

The motor provides a continuous standstill torque of 3.7 Nm, allowing moderate loads to be held without an external brake during normal operation. Under rated excitation, the rotor reaches 3000 rpm, matching the speed class used by many packaging and indexing applications. Size code 090 identifies the stator diameter, and length code A denotes the shortest stack in the family for installations with limited space. The short stack also helps preserve installation room around adjacent components. Because the motor is delivered without a blocking brake, holding force must be supplied by drive torque or an external clamp when power is removed.
