Product Description:
The MDD112D-N-030-N8M-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for automated axes controlled by digital drives. It belongs to the MDD Synchronous Motors series and is used with digital drive controllers to convert commanded current into precise rotary motion for positioning, indexing, and continuous processing tasks. Its 112 frame size and D-length housing provide a larger active motor section than shorter versions in the same platform. In packaging, transfer, and handling systems, this supports smooth acceleration, repeatable positioning, and stable speed control. The standard housing is intended for installation inside protected machine compartments where compact, accurate motion is required.
Mechanical mounting is centered on a 130 mm pilot, which helps align the motor accurately to the machine interface. Power and feedback conductors exit on Side B through a sealed connector, which keeps cable routing orderly and supports a protected connection point. The motor can deliver a continuous standstill torque of 38.0 Nm, and it reaches a nominal operating speed of 3000 rpm for demanding motion cycles. A shaft with a keyway provides a positive mechanical drive interface, while standard balancing helps reduce residual vibration during operation. This layout is useful when the motor is installed against machine plates or coupled to gearboxes that require consistent centering and clear rear cable access.
For load retention during power loss, the motor is equipped with a blocking brake rated at 14.0 Nm of holding torque. Position data is supplied by an integrated multi-turn absolute encoder, and velocity information is returned through digital servo feedback so the controller can manage both speed and position loops accurately. Because the encoder stores position across multiple revolutions, the drive can recover axis location after power-up without an additional reference move in many applications. A factory-installed shaft seal helps prevent lubricant migration along the shaft journal and supports use where coolant splash may be present. This arrangement supports controlled restarting and predictable stopping behavior when the drive is not actively powering the motor.
