Product Description:

The MDD093D-N-040-N2M-130PB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies regulated rotary motion for position-controlled axes in industrial automation cells. The unit uses a standard housing and standard dynamic balancing to fit directly into existing Rexroth mechanical frames while keeping vibration within acceptable limits. It is intended for closed-loop servo applications where stable speed control and accurate position feedback are required during frequent starts and stops.

Its rated operating point combines a nominal speed of 4000 rpm with a continuous standstill torque of 24.0 Nm, giving a high torque-to-inertia ratio for short indexing cycles. A centering pilot of 130 mm simplifies precise flange alignment and keeps the shaft concentric with the load side. Power and feedback are routed through a single connector. Position data are returned through digital servo feedback (DSF) supported by an integrated multi-turn absolute encoder, so the controller can track shaft position across multiple revolutions even after power is removed. The motor size code 093 and length code D indicate the stack height and thermal capacity for this frame.

Connections exit on Side B, leaving the opposite face free for mounting accessories. A molded shaft seal protects the bearing set from dust or coolant, while the keyway shaft supports positive torque transmission to the driven load. The motor is supplied without a blocking brake, so holding force must be provided by drive torque or an external clamp when power is removed. The standard shaft end on the drive side and the absence of a second shaft on side B help limit overhang loads and keep the mounting arrangement straightforward. This layout also keeps cable routing concentrated on one side of the motor, which is useful in compact machine spaces.
