Product Description:
The MDD115A-N-030-N2M-130PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for integration with digital drive controllers, this motor supplies closed-loop rotary motion for indexing tables, packaging axes, and other automated stations. Its internal resolver is replaced by a multi-turn absolute encoder, allowing the drive to recover exact shaft position after power cycling and reduce restart delays. This feedback arrangement helps maintain accurate positioning when the axis returns to service after an interruption.
At standstill, the motor can deliver a continuous torque of 28.0 Nm, so thermal saturation is avoided during static holding or low-speed cuts. When the inverter applies rated frequency, the rotor reaches 3000 rpm, aligning with mid-range spindle and transfer systems that need quick acceleration without overspeeding gear trains. Mounting is guided by the centering seat diameter of 130 mm, which keeps the stator concentric to the driven load and supports accurate alignment during installation. Power and feedback cabling exit on side B through a sealed connector block, and this orientation eases routing in cabinets where the opposite face is covered by couplings. Position data is returned through Digital servo feedback, giving the controller high-resolution velocity and commutation signals over the full speed range.
The integrated brake provides up to 45.0 Nm of holding torque to help prevent axis drift when power is removed. Torque is transmitted through a steel shaft with a keyway, simplifying rigid coupling to pulleys or pinions. The electrical interface uses a single mil-spec connector, which reduces wiring complexity compared with loose leads. This layout keeps external connections compact and protected at the motor housing. A frame classified as size 115 combines with the A-length housing to keep mass moderate while still accommodating the magnetic stack, and standard balancing, a fitted shaft seal, and the normal-duty enclosure support smooth operation in horizontal or vertical mounting positions.
