Product Description:

The MDD025A-N-100-N2G-040FE1 is a synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as the rotary actuator in compact positioning axes and spindle functions across automated assembly lines. In these roles, the unit converts drive current into precise mechanical motion while the integrated blocking brake keeps the axis fixed whenever power is removed.

This model has motor size 025 and the short motor length code A, giving it a lightweight envelope suited to high-speed duty cycles. A nominal speed of 10000 rpm supports rapid indexing, and the continuous torque at standstill of 0.33 Nm maintains position under constant current. When the system powers down, the blocking brake supplies 1.0 Nm of holding torque so external locks are unnecessary. Resolver feedback, shown here as resolver feedback, returns rotor position signals for tight closed-loop control. The centering diameter is 40 mm, allowing accurate flange alignment with gearboxes or load fixtures. Standard balancing limits shaft vibration at top speed, and the housing is supplied in the standard enclosure style.

The motor’s service connections exit on the left side, and power is routed through a connecting cable with a coupling unit that mates directly with compatible drives. A plain shaft carries the load while omitting keyways to minimize stress concentrations, and the shaft end remains standard without a secondary journal on side B. Because the design is delivered without a shaft seal, the machine builder must shield the shaft interface from coolant or particulate ingress when required. This arrangement is suited to compact, high-speed automation modules where straightforward cable routing and a simple shaft profile are preferred.
