MDD025B-N-100-N2K-040GF0
The MDD025B-N-100-N2K-040GF0 is a synchronous motor in the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Intended for use with digital drive controllers, the unit supplies precisely regulated rotary motion to lightweight indexing tables, small conveyor sections, and pick-and-place stations inside automated lines. Its B-length housing and 025 frame minimize footprint, and the integrated feedback device provides real-time position data so the controller can close velocity and position loops without external sensors. This layout suits compact servo axes where installation space is limited and repeatable motion is required throughout frequent start-stop cycles.
At standstill, the motor delivers a continuous torque of 0.60 Nm; this is the steady mechanical twisting force available without overheating. During operation, it can reach a nominal speed of 10000 rpm, allowing rapid cycle times in compact assemblies. Mechanical alignment to gearboxes or mounts is centered on a 40 mm pilot, helping maintain concentricity between the motor and the load. Power and feedback exit on the right side, which can simplify cable routing when the motor is mounted on the left wall of a cabinet or machine frame. Electrical position reporting relies on resolver feedback, whose analog sine-cosine signals remain accurate at high temperatures and vibration levels and support reliable commutation across the full speed range.
To integrate the motor with surrounding equipment, the stator lead set is supplied as a connecting cable with a coupling unit, which helps reduce installation effort and shields the resolver leads from electrical noise. Mechanical holding torque is not provided because the motor is supplied without a blocking brake, so applications that must hold position at power-off need an external clamp or energized drive torque. A contact-style shaft seal is fitted to limit dust or coolant ingress along the output journal. The drive end uses a plain shaft, allowing pulleys or couplings to be fitted without a keyway and helping keep the rotating system compact.
