MDD025B-N-100-N2G-040PL0
The MDD025B-N-100-N2G-040PL0 is a small-frame synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for digital drive controllers, it converts commanded current into precise rotary motion for axes that require rapid positioning in industrial automation equipment. The motor belongs to size 025 within the series and uses the standard housing and balancing profile. Its compact frame suits handling axes, indexing units, and other mechanisms where low moving mass and precise response are important.
The motor has a centering diameter of 40 mm, while power and feedback enter through a front-mounted connector that keeps cable routing direct in tight layouts. Torque available at standstill reaches 0.60 Nm, providing stable holding and low-speed drive capability for lightweight loads. The unit is supplied without a blocking brake, so external clamping or drive torque must hold the axis when power is removed. Position data is transmitted through resolver feedback, allowing the controller to maintain closed-loop speed and position control even under vibration. Electrical terminations leave the stator housing on the left side, and the standard shaft end has no side-B extension, which simplifies coupling to pulleys or gearboxes.
The motor uses length code B, which balances thermal mass against installation depth. Its nominal speed reaches 10000 rpm, permitting high spindle or pick-and-place velocities when the drive can supply the required voltage. Power is transmitted through a hardened output shaft with a keyway, so torque can be passed to the driven load without slip. A dedicated shaft seal limits lubricant escape and helps keep contaminants away from the resolver cavity. This arrangement also supports direct coupling to small gearheads or timing-belt drives where space around the motor body is limited.
