MDD041A-N-100-N2G-050FB1
The MDD041A-N-100-N2G-050FB1 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat and is designed for use with digital drive controllers. Within an automation cell, it converts drive current into rotary motion for axes that need precise velocity profiling and tight position loops. Its compact frame suits lightweight pick-and-place heads, small indexing tables, and auxiliary spindles that must start and stop repeatedly under closed-loop control. The small frame also helps where adjacent components leave little room around the motor body.
At standstill, the rotor can deliver 0.64 Nm of continuous torque, giving machinery enough static force to resist small process disturbances before commanded motion begins. During operation, the winding-to-shaft ratio supports a nominal speed of 10,000 rpm, allowing fast cycle times when paired with a suitable inverter. When power is removed, the integrated brake can lock the shaft with 1.2 Nm of mechanical torque to help prevent drift on vertical or overhung loads. A plain shaft simplifies coupling to timing pulleys or miniature gearboxes, and the centering pilot measures 50 mm to align the stator housing concentrically in precision mounting fixtures. Standard housing construction and standard dynamic balancing reduce vibration that could affect feedback quality or bearing life.
The motor uses size 041 with length code A, a geometry that limits mass while leaving enough stack height for heat dissipation at the stated duty points. Power and feedback conductors exit on side B through a keyed connector that simplifies cabinet wiring and keeps cable routing organized. Resolver feedback supplies rotor position information to the drive, and the motor is built without a shaft seal, so it is best installed in clean, dry areas or protected from splash with external sealing. The shaft end is provided only on the drive side, which helps keep the opposite end clear in tight machine layouts.
