Product Description:

The MDD025A-N-100-N2K-040ML0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a permanently excited AC motor, it is intended for use with digital drive controllers in precision motion systems. It supplies controlled torque and speed to axis modules used in automated assembly, packaging, and semiconductor handling lines. Because it works within a closed-loop servo system, the motor can respond quickly to changing commands during indexing, feeding, and short travel moves. Its small housing is useful in machine sections where moving mass and installation space must both remain low.

This model sustains a continuous standstill torque of 0.33 Nm, enabling light load holding without overheating. Its rotor is designed for a nominal operating speed of 10000 rpm, permitting rapid positioning cycles when paired with high-bandwidth drives. Accurate mechanical alignment is supported by a 40 mm centering diameter, which helps the motor seat correctly on matching machine interfaces. Electrical power and feedback are routed through left-side connections that terminate in a single connector interface. This arrangement keeps cable routing concentrated on one side of the housing and helps preserve space around adjacent components. The high-speed layout suits small mechanisms that require frequent starts and stops instead of high continuous torque.

The unit is delivered without a blocking brake, so applications that need static holding must rely on the drive or an external clamp. Position data is supplied through resolver feedback, allowing closed-loop control in electrically noisy environments and supporting stable motor commutation. A splined coupling is unnecessary because the shaft is machined with a keyway shaft, which supports direct connection to miniature gearheads or pulleys. The 025 frame size and motor length code A place the stator, feedback device, and bearings in a short housing. Standard balancing and an unvented housing help keep windage low and maintain a compact motor body. The short overall length also leaves room for couplings, pulleys, and cable bends inside dense multi-axis assemblies.
