MDD025B-N-100-N2G-040PC1
The MDD025B-N-100-N2G-040PC1 servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into precise rotary motion in automated assembly lines, labeling heads, and compact gantries. Frame designation 025 and length code B give the motor a short body that suits tight machine spaces while supporting the high rotor speed needed for interpolation tasks. A standard housing and standard balancing help maintain smooth running during continuous duty. Its compact frame is useful where multiple axes must be placed close together on a moving machine section.
A centering collar of 40 mm provides the pilot fit for accurate mounting to the machine face. The motor can sustain 0.60 Nm of continuous torque at standstill, which suits light servo axes that dwell frequently yet must hold position without overheating. During motion it reaches a nominal rotor speed of 10000 rpm, which supports low-inertia tools and short cycle times. Power and feedback conductors exit on side A, and a connecting cable with coupling unit supports direct connection in modular machine frames. The cable outlet arrangement also helps keep wiring clear of the driven load in compact installations.
A resolver feedback system supplies rotor position signals over the full speed range so the drive can regulate speed and position with one sensor set. For vertical axes, a blocking brake rated at 1.0 Nm engages automatically when power is removed and holds the load until drive torque returns. The output shaft uses a keyway and is supplied with a shaft seal, which helps secure torque transmission while limiting the entry of contaminants near the bearing area. The motor has no rear shaft end, which keeps the rotating assembly compact and leaves more space around the non-drive end for machine guarding or nearby components.
