Product Description:

The MDD025B-N-100-N2K-040FB1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies precise rotary motion to tooling, indexing tables, and light handling equipment in automated lines. The design uses a 025 frame size with B length so the active iron length stays short while still allowing high rotor speed. This compact format helps the motor fit in tight installation spaces without reducing response. It is suited to compact motion axes that require accurate speed and position control during repetitive cycles.

The rotor can reach a nominal speed of 10000 rpm, which is the steady speed attainable at rated voltage. At standstill, the stator delivers 0.60 Nm of continuous torque, which is the load it can carry without overheating during continuous operation. A built-in blocking brake provides 1.0 Nm of static holding torque so axes can remain fixed when power is removed. The motor fits a centering pilot of 40 mm for concentric mounting. Cables exit on Side B, and the motor uses a circular connector for cable attachment.

Position data is supplied by an integrated absolute encoder, which provides multi-turn feedback to the drive. A separate channel supplies resolver feedback for commutation and velocity estimation during operation. This arrangement gives the control system position and commutation signals without requiring an external feedback device. The housing uses the standard finned shell, and the mounting pattern follows the dimensions used for this motor size. The output uses a plain shaft without a shaft seal, so it should be installed where liquid ingress is not expected. Because the motor has a standard shaft end and no second shaft at the rear, it can be coupled directly to pinions or belt pulleys with minimal overhang load.
