Product Description:

The MDD025B-N-100-N2K-040FE1 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts controlled three-phase power from the drive into precise rotational motion for small indexing tables, lightweight pick-and-place axes, and other automated equipment. Its high rated speed and compact inertia profile suit packaging lines and laboratory automation where short cycle times and repeatable positioning are important. The compact format is also useful where mounting space is limited and low moving mass helps support fast axis response.

At its nominal speed of 10000 rpm, the rotor can complete rapid positioning cycles without step loss. A continuous standstill torque of 0.60 Nm is available to hold or nudge small loads during slow-speed operation, and this output can be maintained continuously within the motor’s thermal limits. When the axis must remain fixed after shutdown, the integrated blocking brake delivers 1.0 Nm of holding torque to lock the shaft until power is restored. The flange provides a centering diameter of 40 mm, which helps align the motor accurately with gearheads or couplings and limits radial runout. Motion is transferred through a plain shaft, so torque is carried by a friction clamp instead of a keyed connection.

The motor has length code B and frame size 025, creating a slim body suited to tight mechanical packages. Position data is generated by an integrated absolute encoder, giving the controller an immediate reference when power is applied, while resolver feedback supplies robust sinusoidal signals for velocity control. All electrical conductors exit on the left side, and a connecting cable with a coupling unit shortens installation time in compact assemblies. That cable arrangement also helps in layouts where routing space is limited near the machine frame. Standard balancing supports direct coupling to lightweight loads, the housing style is standard, and the shaft is supplied without a shaft seal to reduce drag in high-speed duty.
