Product Description:

The MDD065B-N-040-N2M-095PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotational motion and precise positioning in automated packaging, assembly, and handling stations. This permanent-magnet unit is intended to pair with Indramat drive amplifiers, allowing closed-loop current and position control within compact machine frames. Its compact construction suits machine sections that need accurate axis response without a large motor envelope. It is suited for axes that must hold positioning accuracy during frequent start-stop cycles and speed changes.

The motor has size 065 and frame length B, giving a moderate stack length that balances inertia and torque. The centering pilot on the mounting flange is 95 mm in diameter for accurate coaxial alignment. Continuous stall torque reaches 1.5 Nm, and the unit is rated for a nominal speed of 4000 rpm. Rotor balance uses the standard grade, and the aluminum housing uses the standard version. Power and feedback conductors exit on Side B through a single Connector, helping keep cables away from the driven side. The single outlet point also simplifies routing in installations with limited space behind the motor. A shaft seal limits splash ingress, and the shaft end is a single-ended design without a rear extension.

During power-off intervals, a blocking brake provides 3.0 Nm of holding torque to secure vertical or indexing loads. Servo regulation uses digital servo feedback (DSF) generated by the motor’s integrated multi-turn absolute encoder, which reports absolute rotor position over multiple revolutions. Mechanical coupling to the load is through a shaft with a keyway that accepts standard keyed hubs. This feedback arrangement lets the connected drive read position immediately after startup, which supports controlled motion without a separate reference move.
