Product Description:

The MDD093A-N-040-N2M-110PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for operation with digital drive controllers where precise torque and speed regulation support coordinated machine axes in industrial automation cells. Its synchronous design allows the controller to maintain accurate motion during speed changes, and the compact A-length housing helps the motor fit installations where axial space is limited. This makes it suitable for indexing tables, packaging equipment, and other automated systems that depend on repeatable response.

This model uses a centering diameter of 110 mm to match flanged gearboxes and fixtures. Its rotor is balanced to the standard grade to minimize vibration at the rated speed of 4000 rpm. A continuous standstill torque of 9.2 Nm allows the drive to hold static loads without overcurrent. Power and feedback leads exit on Side B through a sealed connector, which helps in layouts where space behind the motor is limited. Position data is returned through digital servo feedback, and the shaft uses a keyway profile so couplings can transmit torque without slippage. Standard housing surfaces transfer heat to the surrounding air during operation, and the sealed connector keeps the cable interface compact and protected.

For commanded stops or power-off holding, an integral brake supplies 11 Nm of torque and is actuated automatically when the drive disables. Absolute position retention after shutdown comes from the Integrated multiturn absolute encoder, so the axis can restart without a homing move. A fitted shaft seal helps prevent lubricant migration and protects the interior against splash ingress. The output shaft is present only on the drive side, leaving side B blank to keep inertia down. This is useful on vertical or load-sensitive axes that must remain controlled during shutdowns and return to a known position after power is restored.
