Product Description:

The MDD025B-N-100-N2G-040MB1 is a compact permanent-magnet synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It works with compatible digital drive controllers to convert commanded electrical input into controlled mechanical rotation for small automation axes. This makes it suitable for pick-and-place gantries, feeders, and labeling stations where fast response and repeatable torque are important. Its compact size helps it fit narrow machine spaces, and the permanent-magnet design supports precise starts, stops, and speed changes in closed-loop motion systems. That behavior is useful on short-stroke axes that change direction often and still need accurate repeatability.

The motor reaches a nominal shaft speed of 10000 rpm, which supports rapid indexing when short cycle times are required. At standstill, it can supply 0.60 Nm continuously, which is the available torque for static holding or low-speed positioning without exceeding winding temperature. A 40 mm centering diameter helps align the motor accurately with gearheads or mounting flanges. Power and feedback leads exit on side B, and a sealed connector provides a clean cable interface. The centering feature helps maintain concentricity at the mounting interface, and this cable arrangement helps keep routing orderly when moving machine parts pass close to the motor body.

A blocking brake rated at 1.0 Nm locks the rotor when the drive is disabled, helping prevent drift on vertical or intermittent-duty axes. Motion feedback is provided by resolver feedback, which returns rotor position signals for closed-loop control and remains reliable in electrically noisy environments. The frame size is 025, and the shaft uses a keyway to transfer torque without slippage. The motor also has length code B, a single-ended shaft, standard dynamic balancing, and no shaft seal. This layout suits cabinet-enclosed machinery where the shaft area is protected from external contamination.
