Product Description:

The MDD093B-N-040-N2L-110GB1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, this motor converts commanded current into controlled rotary motion for positioning, indexing, and velocity regulation tasks in automated machinery. Its compact 093 frame and B-length housing allow installation in medium-power axes, while the integrated blocking brake maintains shaft position during power loss for vertical or load-holding applications.

The mechanical interface starts with a centering shoulder of 110 mm, allowing the housing to align concentrically with gearboxes or flanges to minimize radial runout. At standstill, the electromagnetic design delivers 14.5 Nm of continuous torque, giving stable holding force for low-speed feed axes without overheating. During operation, the rotor can reach a nominal speed of 4000 rpm, so the drive can command rapid traverse while remaining within the rated operating range. Because the brake produces 11 Nm of static torque, it can secure the load when power is removed and releases automatically when the controller energizes the windings. The output side uses a plain shaft, reducing fixture complexity where keyed transmission elements are not required.

Dynamic accuracy relies on the integrated digital servo feedback (DSF) unit, which returns high-resolution position data to the drive so torque and speed corrections remain synchronized during operation. The stator is factory balanced to the standard grade, limiting vibration when the motor is coupled through the power and signal connector on Side B. A durable shaft seal protects the output journal from coolant splash and airborne debris. The single-ended shaft arrangement, supplied without an auxiliary side-B output, reduces mounting depth and leaves more room for adjacent machine components.
