Product Description:

The MDD025B-N-100-N2G-040PC1 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers, where it converts commanded current into precise rotary motion for compact axes in pick-and-place units, labeling stations, or small conveyor sections. This arrangement suits compact automation equipment that needs fast and repeatable motion in a limited installation space. Power and feedback conductors exit on Side A, which helps simplify cable routing when the motor is mounted with the flange facing the drive.

At standstill, the motor can deliver a continuous torque of 0.60 Nm, allowing it to hold light loads without overheating during static positioning tasks. Once energized, the rotor can reach a nominal speed of 10000 rpm, which supports rapid cycle times in equipment that must start, stop, and reverse quickly. That combination is well suited to light-duty axes that require short and repeatable motion cycles. Accurate mechanical alignment to the machine frame is aided by a centering diameter of 40 mm, which helps locate the housing concentrically and reduce vibration. Torque is transmitted through a shaft with a keyway, providing a positive-drive connection for pulleys, gears, or couplings without relying on friction alone.

For safety at power-off, the motor has an integrated blocking brake that holds the shaft with 1.0 Nm of torque so suspended or inclined loads do not drift. Rotor position is returned to the controller through resolver feedback, enabling the drive to close velocity and position loops even during acceleration from zero speed. This feedback method also supports stable low-speed control during repeated indexing tasks. The motor belongs to size code 025, meaning its stator diameter, bolt circle, and thermal mass match other 25-frame devices in the series.
