Product Description:

The MDD093D-N-040-N2L-130PL1 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts regulated electrical power into rotary motion for positioning tables, pick-and-place units, and other automated axes. The brushless design supports smooth servo response and low maintenance because there are no brushes to wear during normal service. Its type designation identifies the frame size, winding class, feedback format, and mechanical options so the motor can be matched to the application without changing the standard 093-frame mounting envelope.

The motor’s flange uses a centering diameter of 130 mm, allowing accurate alignment with couplings or gearboxes. Power and feedback connectors exit on the left side, which can simplify cable routing when the drive cabinet is located on that side of the machine. This layout can also reduce cable bending near the motor housing in side-entry installations. During standstill, the stator windings can supply 24.0 Nm of continuous torque without exceeding thermal limits. For load holding after power is removed, the integrated blocking brake provides 11 Nm of static torque. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm, supporting high axis travel rates while standard dynamic balancing helps reduce vibration.

Closed-loop control is supported by built-in digital servo feedback (DSF), which sends position data to the controller during operation. This feedback arrangement helps the drive maintain stable speed regulation and repeatable positioning across changing load conditions. A shaft seal at the output end helps reduce contamination ingress near the front bearing. Torque is transmitted through a keyway machined into the solid shaft, allowing connection to keyed hubs and similar drive elements. The stator uses length code D, which gives the motor a longer active stack for higher torque density within the same frame size.
