Product Description:

The MDD093A-N-040-N2M-110GR0 is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Intended for digital drive controllers, it converts electrical setpoints into precise mechanical rotation for positioning, indexing, and speed-regulated axes in automated machinery. A centering diameter of 110 mm aligns the flange to gearboxes or machine plates, helping the motor fit standard mounting surfaces. Its synchronous design supports accurate speed response and repeatable positioning when it is paired with a compatible drive.

At standstill, the rotor can deliver a continuous torque of 9.2 Nm, allowing stable holding force without thermal overload when the axis remains in position. During normal operation, the winding is optimized for a nominal speed of 4000 rpm, so the motor can match fast linear movements demanded by packaging or pick-and-place stations. The motor uses frame size 093 with length code A, which gives it a compact housing for medium-duty motion axes. Power and feedback cables exit on the right side, simplifying cabinet layouts when the motor is mounted in mirrored pairs, and the single plug-in connector simplifies cable attachment compared with hard-wired terminals. Standard rotor balancing keeps vibration within ISO limits for smooth high-speed cycles and steady running in repeated motion patterns.

The sensing layer is an integrated multi-turn absolute encoder that delivers position data through digital servo feedback. This interface lets the controller read rotor angle over multiple revolutions without a homing routine and supports immediate closed-loop positioning after startup. Because the motor is supplied without a blocking brake, stopping torque must be provided by the drive or an external clamp when power is removed. A plain shaft permits direct coupling to precision couplings, and a fitted shaft seal helps prevent lubricant migration along the journal while supporting enclosure protection in dusty or coolant-prone areas. This layout suits applications that need accurate feedback, direct shaft coupling, and sealed mechanical output without added brake hardware.
