MDD025B-N-100-N2K-040PE0
The MDD025B-N-100-N2K-040PE0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It interfaces with digital drive controllers to deliver closed-loop motion in assembly stations, pick-and-place axes, and other automated tooling. The motor converts electrical power into controlled rotary motion while sending position data to the drive so repeated machine cycles remain stable and accurate. Its compact form suits conveyors, indexing mechanisms, and small handling modules where precise speed and position control are required.
At its nominal operating point, the rotor reaches 10000 rpm, which supports high-speed operation in light mechanical loads. It provides a continuous stall torque of 0.60 Nm, so the motor can hold or creep at low speed within its thermal limits. The centering pilot measures 40 mm, which helps align the motor accurately on matching brackets or gearheads. Motion feedback is provided through resolver feedback, allowing the drive to close the velocity and torque loops. The motor is supplied without a blocking brake, so holding force must be provided externally when power is removed.
The motor uses size code 025 and length code B, which give it a slim body for closely spaced multi-axis layouts. Power and feedback connections exit on the left side through a connecting cable with a coupling unit, which reduces the space needed behind the motor compared with fixed rear plugs. The output shaft uses a keyway for positive torque transfer, and the shaft end is fitted with a shaft seal to help limit lubricant migration toward the bearings. This cable routing arrangement also helps in shallow enclosures where rear clearance is limited. Standard rotor balancing helps reduce vibration during operation, and the compact housing supports consistent installation in small machine assemblies.
