Product Description:

The MDD093A-N-030-N9N-110PS0/S047 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It interfaces directly with digital drive controllers, converting commanded current into precise rotary motion for positioning, conveying, or machining functions on automated lines.

This motor delivers a continuous stand-still torque of 9.2 Nm, meaning it can sustain that load indefinitely without overheating when the rotor is locked. The centering diameter is 110 mm, so the mounting flange aligns concentrically with machine fixtures of the same bore to keep shaft runout low. A nominal speed of 3000 min⁻¹ defines the rated mechanical speed reached when the drive applies its rated frequency and voltage; application duty cycles should be planned around that velocity. Frame designation 093 identifies the stator outside diameter used across the series, while the motor length is the shortest variant identified by length code A, resulting in a compact package that still meets the listed torque rating.

For applications that rely on external holding mechanisms, the unit is supplied without a blocking brake, eliminating brake mass and simplifying maintenance. The rotor is finished with standard balancing, keeping vibration levels within general-purpose limits for horizontally mounted axes. A radial shaft seal sits behind the front bearing to prevent dust or coolant from reaching internal windings, extending bearing service life in moderately contaminated environments. Power is transferred through a keyway shaft, providing positive torque locking with conventional keyed couplings or pulleys, and the standard cast housing dissipates heat by natural conduction and convection when the motor is surface mounted to a grounded machine plate.
