Product Description:

The MDD065B-N-040-N2L-095PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is used with digital drive controllers for closed-loop speed and position control on automated machinery. The motor converts commanded current into mechanical rotation for axes such as tool positioning, conveying, and indexing. This makes it suitable for machine functions that need repeatable starts, stops, and speed changes throughout a production cycle.

The flange uses a centering diameter of 95 mm for accurate alignment to the machine frame. Power and encoder conductors exit on Side B, and the factory-installed Connector supports direct plug-in wiring. Under continuous standstill conditions, the motor delivers 1.5 Nm of torque. The housing uses standard geometry with motor size 065 and length code B, which keeps the unit compact while leaving room for the internal rotor mass. The side-mounted cable exit can help when the motor is installed near guards or machine plates where rear clearance is limited. This layout also helps the motor fit into narrow tooling areas without special mounting adapters.

During operation, the rotor can reach 4000 rpm, which suits light inertial loads that require frequent acceleration. Position data are returned through digital servo feedback (DSF), allowing the drive to correct error within each control cycle. This feedback arrangement lets the controller monitor rotor position continuously instead of relying on open-loop operation. The motor is supplied without a blocking brake, so static holding force must come from the drive or external mechanics. Torque is transmitted through a keyway, and a fitted shaft seal helps protect the internal bearings from coolant or dust. The motor uses a single-ended shaft with no extension on the opposite side, which keeps the output arrangement straightforward for coupling to the driven load.
