Product Description:

The MDD090A-N-040-N2M-130PA1 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. The unit is intended for direct coupling with digital drive controllers, providing precise torque and speed regulation in automated machinery cells. It belongs to motor size 090 and uses length code A, which suits installations that require a short axial dimension. Standard housing and standard dynamic balancing support smooth operation on conveyors, gantries, packaging lines, indexing tables, and other equipment where stable motion and compact motor length are important.

Primary mechanical interfaces start with a centering shoulder of 130 mm, allowing accurate registration against gearbox flanges and machine mounting faces. Power and feedback conductors exit on Side A, and a factory-mounted connector keeps the electrical connection compact at the cable entry point. Under continuous stall conditions, the motor delivers 3.7 Nm of torque, and its winding supports a rated speed of 4000 rpm for fast servo operation. The standard shaft end is present only on the drive side, which helps keep the motor envelope simple and avoids extra projection at the rear. A shaft seal is fitted to reduce the entry of dust or fluid into the bearing area.

Position data is generated by an integrated multi-turn absolute encoder and returned through digital servo feedback for closed-loop control across the operating range. For power-off holding, an integrated blocking brake can resist 6.5 Nm of load on the shaft, which helps hold the axis when supply power is removed. The output shaft uses a keyway profile so couplings and driven elements can transmit torque with positive mechanical engagement. Standard housing construction and a balanced rotor support steady running, while the missing side B shaft extension leaves more room around the rear of the motor for adjacent machine components and simplifies nearby mechanical layout.
