Product Description:

The MDD093B-N-040-N2M-110GB2 is a synchronous AC servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies closed-loop rotary motion in automated machine tools, packaging stations, and handling axes. The unit connects to cabinet-mounted drives through a single power and feedback connector, allowing the controller to command torque and velocity directly for precise positioning tasks. This arrangement supports accurate speed regulation during indexing moves and other repeatable machine cycles. It is suited for axes that need controlled acceleration, steady low-speed motion, and repeatable stopping points across frequent start-and-stop sequences.

This model sustains a continuous torque of 14.5 Nm at standstill, allowing it to hold mechanical loads without movement while current flows through the stator windings. The rotor reaches a nominal speed of 4000 rpm during operation, which suits high-speed production cycles. A centering diameter of 110 mm aligns the motor housing with gearboxes or mounting flanges, helping maintain accurate shaft positioning at installation. Cables exit on side B, which can simplify routing in compact enclosures when the unit uses a single circular connector. Motion feedback comes from an integrated multi-turn absolute encoder, so the drive can retain position information after power loss. The plain shaft without a side B extension mates directly to couplings or pulleys, and the B-length housing keeps the motor within the expected frame envelope.

A blocking brake provides emergency restraint with a holding capacity of 22 Nm, helping keep suspended or vertical loads from drifting when the servo is disabled. Protection against lubricant ingress is provided by a shaft seal, which helps protect the bearing area during normal machine operation. The motor uses frame size 093, which sets the flange pattern and overall dimensions used for layout planning. Position data is transferred as digital servo feedback, keeping the control loop responsive while avoiding analog drift. Because the feedback remains digital from the motor to the drive, signal quality stays stable over the connection path and supports consistent position correction. Standard balancing helps reduce vibration during normal rotation.
