Product Description:

The MDD115D-N-020-N2M-130PA0 is a three-phase synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for digital drive controllers and converts regulated current into precise rotary motion for indexing, interpolation, and continuous-speed automation tasks. The 115 frame size and D-length housing give the motor the thermal capacity needed for medium-inertia loads, while the standard housing and standard balancing support direct installation on machine frames without special vibration measures.

For continuous duty, the motor provides 57.0 Nm of standstill torque and reaches a nominal speed of 2000 rpm, giving the connected drive a practical operating range for acceleration and steady running. A centering pilot of 130 mm helps align the flange accurately to the machine, and the shaft seal helps keep dust and coolant away from the front bearing. Power and feedback conductors exit on Side A through a single connector, which helps simplify cable routing when the shaft faces the driven load. The control loop receives position data through digital servo feedback, allowing stable speed and position control when operating conditions change quickly.

An integrated multiturn absolute encoder reports both angular position and full-revolution count, so the axis can retain position information after power is restored. The motor is supplied without a blocking brake, so any holding function must be provided by drive torque or by an external clamping device. A keyway shaft end transmits torque securely to couplings and pulleys, and the lack of a side-B shaft helps keep the overall motor length shorter for compact installations. Standard housing materials and the shaft seal support regular factory use where clean mounting, reliable feedback, and protected front-bearing operation are important.
