MDD025A-N-100-N2G-040FE0
The MDD025A-N-100-N2G-040FE0 is a synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Built for use with digital drive controllers, it delivers regulated torque and speed for compact automation axes that require accurate motion control. Standard balancing helps reduce shaft vibration during operation, and the standard enclosure supports installation in typical industrial equipment. The short motor length code A is suited to applications where available mounting depth is limited, and the shaft end is provided only on side A for single-ended coupling arrangements.
This model sustains a continuous standstill torque of 0.33 Nm, which supports stable position holding on light-duty axes. During operation, the rotor reaches a nominal speed of 10,000 rpm, making it suitable for fast indexing and feeder movements. A centering diameter of 40 mm provides accurate alignment between the motor flange and the mating machine surface. Power and feedback conductors exit on the left side, and the motor uses a connecting cable with coupling unit instead of a fixed plug. This cable arrangement supports flexible lead routing, while the unsealed shaft area means the mounting location should remain free of coolant splash and oil mist.
Rotor position is reported through resolver feedback, which gives the controller reliable angle information across the operating range. The motor uses frame size 025, helping keep inertia low for repeated start-stop motion and quick response. A plain shaft allows the use of press-fit hubs or collets where keyed transmission is not required. Because the unit is supplied without a blocking brake, holding force at standstill must come from drive torque or an external mechanical device. This layout fits small servo axes that need high rotational speed, low inertia, and direct integration with closed-loop control.
