Product Description:

The MDD093D-N-020-N2L-130GL2 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is identified by motor size 093 and the D length code, which gives it a deeper stator stack than shorter variants. The unit is balanced to the standard grade and uses a standard housing that supports natural convection cooling. Supplied as a motor for digital drive controllers, it has a standard shaft end on side A only, which simplifies coupling design in automated axis modules. This layout suits controlled motion applications that need direct motor integration without external cooling hardware.

Its mechanical interface starts with a centering flange that measures 130 mm in diameter, ensuring concentric alignment within precision machinery frames. Electrical and feedback plug faces are oriented on the left side of the stator body, so cables can be routed away from moving guides or adjacent machine members. A single multipole connector handles power, resolver, and brake conductors, which reduces the number of separate connection points at the motor. Position and velocity loops are closed through digital servo feedback (DSF), which sends position data to the drive for closed-loop control. Under continuous stall conditions, the motor can develop 24.0 Nm of torque, giving it useful holding capability in rotary tables, feed axes, and vertical motion systems.

A blocking brake is integrated, and during power-off it applies a clamping force of 22 Nm to lock the rotor. When the axis is released, the machine can accelerate to its rated speed of 2000 rpm while remaining within the motor’s permissible temperature rise. The mechanical output is delivered through a plain shaft with a shaft seal that helps protect the bearing cavity from contamination and lubricant migration. This combination supports driven axes that need positive stopping behavior when power is removed and sealed shaft output during operation.
