Product Description:

The MDD025A-N-100-N2G-040FA1 is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies regulated rotary motion for positioning tables, compact actuators, and other small-scale automation tasks that call for precise speed tracking and repeatable indexing. The housing uses the standard enclosure style, and the shaft is plain without a second end. No shaft seal is fitted, so external sealing is needed where liquid ingress is possible. Its compact format is suitable for assemblies where limited installation space must still support controlled acceleration and stable speed regulation.

At standstill the motor can deliver 0.33 Nm of continuous torque, a value that indicates the steady load it may support without excessive heating. Its rated speed reaches 10000 rpm, enabling high spindle or feed speeds when paired with light gear reductions. Alignment during mounting is handled by a 40 mm centering diameter that seats the stator in the machine frame. The motor has a size code of 025 and a length code of A, indicating the shortest active stack in this frame. Electrical position feedback is provided by resolver feedback, which supplies rotor angle information that remains reliable through rapid acceleration. The electrical terminals face Side A of the housing to keep cable runs short inside the enclosure. The short active stack also helps the motor fit into compact machine sections where axial space is limited.

For static holding, a brake rated at 1.0 Nm supplies clamping force. This blocking brake secures the shaft when power is removed or an emergency stop is triggered. The rotor is trimmed to standard tolerance with Standard balancing so coupling can occur without additional machining. Because all power and signal leads connect through a single connector, cable routing stays compact inside the machine.
