Product Description:

The MDD025C-N-100-N2K-040PD0 is a compact AC synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies precise rotational power for light-duty automation axes, pick-and-place heads, and small spindle drives in compact machinery. In this role, the unit converts regulated electrical output from its drive into tightly controlled mechanical motion, making it suitable for coordinated multi-axis industrial systems where repeatable speed and position control are required.

The centering pilot measures 40 mm, creating the positioning surface that aligns the stator in the machine frame. Power and feedback leads exit on side B, so panel layouts can keep cable bends short when the motor is mounted to a gearbox. At standstill, the rotor can deliver 0.90 Nm continuously, which suits micro-grippers and miniature conveyors. During operation, the windings allow the shaft to reach 10,000 rpm, giving high peripheral speed despite the compact frame. An integrated absolute encoder supplies single-turn position data directly to the drive, allowing position detection after power-up without auxiliary sensors. The connection type is a pre-wired cable with a coupling unit, and the housing and rotor balancing follow the standard version for this motor line.

Electrical interfaces are removable, and the unit is supplied without a blocking brake, so static loads must be held by drive torque or an external latch. Rotor angle can also be processed through resolver feedback, allowing analog velocity loops in compatible controllers. The output shaft carries a keyway and is single-ended, while the opposite side remains closed. Contamination ingress is limited because the motor is configured with a shaft seal. Length code C indicates the third longest body for this frame, and the standard housing supports use in general factory environments that demand high speed in a small motor package.
