Product Description:
The MDD115B-N-020-N2L-130GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts inverter output into controlled rotary motion for automated machinery axes such as feed drives, handling systems, and positioning tables. The motor uses a midsize housing with B length, which helps it fit machine layouts that need solid torque capacity without moving to a larger frame. Because it is a synchronous servo motor, it is intended for coordinated axis motion rather than simple constant-speed duty. That makes it suitable for applications where the controller must respond quickly to changing commands and load conditions.
It delivers a continuous standstill torque of 38.0 Nm, which indicates the load the motor can hold at zero speed with rated current applied. During power-off holding, the integrated blocking brake supplies 45.0 Nm of mechanical torque to keep the shaft from drifting on vertical or suspended axes. At a nominal rotor speed of 2000 rpm, the motor reaches its rated operating speed within the standard mechanical layout. Position and velocity data are returned through digital servo feedback (DSF), allowing the drive to maintain precise closed-loop control. The frame size is 115, which places the motor in the midsize range of the MDD line.
The flange has a centering pilot of 130 mm, which helps align the motor accurately with mounting plates or gearboxes. Power and feedback conductors exit on side A through a keyed connector, which keeps the electrical interface compact and supports straightforward cable routing. The output uses a plain shaft with a factory-installed shaft seal, allowing direct coupling to clamped hubs while helping keep oil or coolant out of the bearing area. The motor has no side-B shaft extension, which keeps the overall length shorter and leaves more room around adjacent machine components. The sealed shaft end is useful where splash or light contamination may be present near the coupling area. A keyed plug connection also reduces the chance of incorrect orientation during installation.
