Product Description:

The MDD093A-N-020-N2M-130PL2 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It is intended for digital drive controllers and provides commanded rotary motion in industrial automation systems that require precise feedback regulation, coordinated positioning, and reliable braking capability. Because it uses brushless construction, electronic commutation is handled by the matching drive, which supports smooth torque production and reduces wear associated with brush contact. Its standard housing and standard rotor balancing support installation in machinery that uses this motor format without additional alignment or sealing changes.

The motor has a centering diameter of 130 mm, which mates with a machined mounting pilot to keep the stator concentric to the driven load. Under continuous stall conditions, it delivers 9.2 Nm of torque, allowing it to hold or slowly move loads while the drive maintains full current. At its rated excitation frequency, the rotor reaches a nominal speed of 2000 rpm, which sets the base velocity for positioning profiles calculated in the controller. A factory-installed blocking brake generates 22 Nm of static holding torque, so vertical or overhung axes can remain secured when power is removed.

All control signals and power conductors exit on the left side through a keyed connector, which can simplify cable routing inside compact enclosures and helps maintain a consistent mating orientation. Rotor position is reported by an integrated multi-turn absolute encoder, and the drive receives this information as digital servo feedback (DSF) for closed-loop position and velocity regulation. This feedback arrangement allows the control system to track rotor position over multiple revolutions and supports stable motion control during repeated start and stop cycles. A shaft seal helps limit oil and dust ingress at the shaft interface, while a keyway machined into the shaft end transfers torque to couplings.
