Product Description:

The MDD025A-N-100-N2K-040MF0 is a compact synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended to pair with digital drive controllers so that motion control systems can achieve fast, repeatable positioning in small automation stages, pick-and-place devices, or spindle applications. Its compact format also suits installations where available mounting space is limited. The motor is intended for precise motion tasks that need quick response and stable feedback.

This model uses frame code 025, and its centering register measures 40 mm, allowing direct mounting to gearboxes or machine frames with minimal alignment error. At standstill, the motor can generate 0.33 Nm of continuous torque, and under rated excitation it reaches a nominal speed of 10000 rpm. These values describe the continuous operating range available to a connected axis. Rotor position data is supplied by an integrated absolute encoder, while real-time commutation signals come from resolver feedback, giving the controller detailed position information and stable angle data for current control. The motor uses standard balancing and a standard housing, and the A-length stator stack helps it fit into shortened machine compartments without changing the coil layout.

Cabling exits on the right side of the stator and is terminated through a connecting cable with coupling unit, which helps simplify routing in compact enclosures. The single-ended shaft is machined with a keyway, and there is no shaft on side B, which reduces overhung mass in belt or gear drives. The motor is supplied without a blocking brake, so an external brake or holding torque from the drive is needed when a load must remain fixed at standstill. A shaft seal is not fitted, which helps reduce friction at high speed. The shaft end follows the standard form used for this motor size.
