Product Description:

The MDD025A-N-100-N2K-040FE0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed in industrial automation equipment to deliver regulated torque and speed to light-duty rotary axes, pick-and-place heads, and other precision mechanisms where space is limited and high rotational velocity is essential. The motor uses size code 025 and length code A, giving it a short body that fits beside adjacent axes. Its compact frame also suits small machine assemblies where nearby components leave little installation space.

This model delivers a continuous standstill torque of 0.33 Nm, enabling it to hold position or start loads without overheating under rated current. During motion, its nominal speed reaches 10,000 rpm, supporting rapid cycle times in indexing or spindle applications. Accurate mechanical alignment is assisted by a centering diameter of 40 mm, while power and feedback conductors exit on the left side to simplify cable routing in tight enclosures. The rotor is dynamically balanced to the standard grade, which helps maintain smooth running at high speed, and the housing is the standard uncooled variant suited for cabinet environments. A plain shaft reduces runout for couplings or collet grips. There is no shaft seal, so the installation must avoid fluid ingress.

Position transducers are integrated in the motor housing. The unit carries an integrated absolute encoder for single-turn position capture, and the drive uses resolver feedback for closed-loop control. Mechanical holding is external because the unit is supplied without a blocking brake. Electrical connection is made through a connecting cable with coupling unit, which allows quick motor disconnection when needed. A standard shaft end is provided only on the drive side, which suits direct coupling arrangements in compact mechanisms.
