Product Description:

The MDD025B-N-100-N2K-040GE1 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is used with digital drive controllers and converts commanded current into precise rotary motion for positioning axes and high-speed spindle duties in automated machinery. The motor has a compact housing and a plain shaft for direct coupling to light transmission elements, while the integrated feedback system supplies single-turn position data to the control loop. Its feedback arrangement helps the drive maintain stable position and speed control during short, repetitive motion cycles.

The motor delivers 0.60 Nm of continuous standstill torque and reaches a nominal speed of 10,000 rpm, which suits rapid indexing with limited thermal rise. A blocking brake rated at 1.0 Nm locks the rotor when power is removed, which helps prevent drift on vertical or load-holding axes. The brake is useful when the axis must remain in place after shutdown. Alignment during mounting is guided by a centering diameter of 40 mm. All power and feedback leads exit on the left side, and standard dynamic balancing helps reduce vibration during high-speed operation. The connecting cable uses a coupling unit instead of hard-wired terminations.

The motor housing uses the standard MDD envelope and includes a fitted shaft seal that helps keep lubricants in and contaminants out. Resolver feedback is available in parallel with the integrated absolute encoder, allowing the drive controller to receive position information during startup and normal operation. The output uses a plain shaft, so there are no keys or threads that could affect concentricity. This version has no side B shaft end, which keeps the rear of the motor closed. Motor size 025 and length code B identify the mechanical envelope for matching brackets and available installation space.
