Product Description:

The MDD093D-N-040-N2M-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for connection to digital drive controllers, it converts controlled current from an inverter into precise rotary motion for positioning tables, gantries, and processing spindles in automated lines. The motor includes an internal feedback device so the controller can close position and velocity loops without external sensors. This integrated arrangement reduces added cabling around the axis and keeps the motor assembly compact for general industrial machines.

The centering shoulder measures 130 mm, which helps align the motor accurately to machine frames and reduce runout under load. When energized, the rotor can deliver a continuous standstill torque of 24.0 Nm, allowing the axis to hold static loads without overheating. The winding is optimized for a nominal speed of 4000 rpm, supporting high surface velocity while staying within the thermal capability of the standard housing. All power and feedback conductors exit on side A, and a single connector carries these connections so separate terminal strips are unnecessary. The keyed shaft includes a shaft seal, which supports secure coupling to gears or pulleys while helping limit lubricant entry.

Control precision comes from an integrated multiturn absolute encoder, which reports position through digital servo feedback (DSF) so the drive can recover the exact angle after a power interruption without a homing routine. The motor uses the D length code, giving it a deeper stator stack than shorter versions and increasing rated torque without enlarging the 093 frame. For applications that use external clamps or drive torque for holding, it is supplied without a blocking brake, which reduces passive drag during acceleration and deceleration. Standard dynamic balancing and a sealed housing support smooth running across the speed range and help protect internal parts during normal machine operation.
