Product Description:

The MDD025B-N-100-N2K-040PD1 is a compact servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied in a standard housing configuration and uses standard dynamic balancing, allowing direct integration into light automation stages. Classified as a motor for digital drive controllers, it delivers rotational motion to small tooling, pick-and-place heads, or indexing tables where space limits and rapid cycle times dominate the design requirements.

During continuous stall conditions, the rotor can generate 0.60 Nm of torque while maintaining thermal limits, and the shaft can accelerate to a nominal speed of 10000 rpm under rated voltage from the associated drive. A blocking brake is fitted and provides a holding force of 1.0 Nm to secure vertical or suspended loads when power is removed. Mechanical alignment to machine frames is achieved with a centering diameter of 40 mm, and power plus feedback conductors exit on side B, so cable routing stays clear of the driven end. The keyed shaft matches standard couplings, and a shaft seal prevents lubricant migration into the motor’s interior. A single connecting cable with a coupling unit completes the electrical interface, and the shaft end follows the standard layout without an additional extension on side B.

Position and speed control rely on an integrated feedback chain that combines integrated absolute encoder data with resolver feedback signals for drive compatibility. The stator package is identified by motor size 025, and its active length corresponds to motor length code B. This combination indicates the stack height and winding volume inside the frame. A permanently installed shaft seal safeguards the front bearing, and the keyway shaft type eases rigid coupling selection for low-inertia loads without adding clamping adapters.
