Product Description:

The MDD065B-N-040-N2M-095PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated electrical power from an inverter into mechanical rotation for positioning tasks in automated machinery, packaging stations, and handling modules. A permanently excited rotor and electronic commutation allow rapid speed changes, while the integrated feedback path keeps the drive in closed-loop alignment with motion commands from the controller. This arrangement supports accurate starts, stops, and repeatable axis movement during normal machine operation.

The motor reaches a nominal speed of 4000 rpm, enabling moderate-to-high shaft velocities for indexing or continuous-duty axes. At standstill, it can deliver 1.5 Nm of continuous torque, so low-speed feed motions and holding duty can be sustained without overheating. When power is removed, a blocking brake applies up to 3.0 Nm of mechanical holding torque to secure vertical or suspended loads. Position data are returned through an integrated multi-turn absolute encoder, giving the controller an absolute position reference across multiple revolutions. Signal transmission uses digital servo feedback (DSF), which supports high-resolution communication between the motor and the drive.

The centering pilot measures 95 mm, helping the motor seat accurately in the machine interface. The power and feedback connectors are oriented to the right side of the stator housing to simplify cable routing. A sealed connector coupling handles both power and signal cores, while the shaft uses a keyway profile for positive locking to couplings or pulleys. Standard dynamic balancing minimizes vibration, and a factory-installed shaft seal helps block dust and spray from entering the front bearing. Size code 065 and length code B set the frame envelope for compact servo applications that require low inertia and quick acceleration.
