MDD065D-N-040-N2M-095PR1
The MDD065D-N-040-N2M-095PR1 synchronous motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical power from the drive into mechanical rotation for position-controlled axes in automated machinery. It is suitable for feed axes, indexing units, and other servo applications that require accurate motion in a compact package. This arrangement supports controlled starts, stops, and speed changes during normal machine operation.
This model develops a continuous standstill torque of 2.7 Nm, allowing it to hold loads at zero speed without overheating. During emergency stops or power loss, a blocking brake supplies 3.0 Nm of static torque to keep the axis locked until release. The brake also helps prevent unwanted movement while the drive is disabled. Under rated drive voltage, the rotor reaches a nominal speed of 4000 rpm, which supports fast positioning and steady operation when the internal magnetic fields remain synchronized with the inverter frequency. Accurate shaft alignment is aided by a centering diameter of 95 mm, and installation is simplified because all power and feedback plugs are oriented to the right side of the housing.
Position feedback is handled through digital servo feedback (DSF) from an integrated multiturn absolute encoder, enabling the drive to track several revolutions without a homing routine after startup. A standard housing with standard balancing helps maintain smooth operation, and a keyway shaft with a shaft seal supports secure torque transfer while helping limit contamination at the output end. The motor uses a single-ended shaft configuration without a side B extension, and electrical as well as sensor conductors connect through a standard interface used with this motor type. The connector layout keeps motor power and feedback wiring grouped at the connection point for orderly cable routing.
