Product Description:

Bosch Rexroth Indramat manufactures the MDD025B-N-100-N2K-040PR1, a member of the MDD Synchronous Motors series. Intended for digital drive controllers, this servo unit supplies tightly regulated torque and speed so that compact automation axes achieve predictable positioning and cycle times in production machinery. Its small frame suits lightweight handling systems, indexing devices, and other installations where compact servo response and repeatable motion are important.

The motor reaches a nominal speed of 10,000 rpm, allowing fast traverses when paired with a suitable inverter. At standstill, it can deliver 0.60 Nm continuously, giving stable holding force without overheating during static clamping or low-speed feed operations. A blocking brake is installed, and its rated torque of 1.0 Nm helps keep vertical loads in place after power removal. Mechanical alignment is aided by a centering flange with a diameter of 40 mm. The shaft is machined with a keyway, so pulleys or couplings can lock in rotational phase. Connections exit on the right side through a sealed circular connector, and a shaft seal helps keep contaminants away from internal components. The housing follows the standard frame outline, and the shaft end is provided only on side A to limit overhung mass.

Control feedback uses resolver feedback, and rotor position is also captured by an integrated absolute encoder for multiturn reference tracking. Dynamic proportions correspond to motor length code B within frame size 025, giving the unit a compact form for small servo axes. The rotor is balanced to the standard grade for smooth running during normal operation. The compact stator envelope, right-side connection orientation, and included shaft seal help keep cable routing orderly and maintain enclosure integrity when the motor is installed on small pick-and-place heads or miniature conveyors.
