Product Description:

The MDD025C-N-100-N2K-040FE0 is a synchronous servo unit produced by Bosch Rexroth Indramat and delivered within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it serves as the rotary actuator in tightly integrated industrial automation stages, translating current-controlled commands into precise speed and position suitable for compact pick-and-place modules, miniature spindles, and other high-velocity axes.

A standard-balanced rotor keeps vibration low, and the centering flange is maintained at 40 mm to ensure coaxial seating with the machine frame. The unit sustains a continuous standstill torque of 0.90 Nm, giving it the ability to hold light loads without thermal derating. When the controller demands velocity, the shaft can accelerate to a nominal 10000 min⁻¹. Power, feedback, and brake conductors exit on the left via a connecting cable with coupling unit, simplifying inline mounting. Position information is obtained from an integrated absolute encoder, so the drive powers up with immediate knowledge of rotor angle.

In addition to the encoder, the control loop can reference resolver feedback for commutation during rapid reversals. The motor body corresponds to length code C and size 025, fitting the series’ standard housing. A plain shaft on the A side is supplied without a side-B extension, and the unit is delivered without a shaft seal, so external guarding is recommended in wet zones. It is also shipped without a blocking brake, leaving static holding to mechanical locks or drive torque. Dynamic integrity is supported by standard balancing and insulation rated by Bosch Rexroth Indramat.
