MDD025B-N-100-N2G-040MF0
The MDD025B-N-100-N2G-040MF0 is a compact synchronous servo motor in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current from the amplifier is converted into accurate rotary motion for small automation axes. This operating concept supports precise speed and position control in miniature assembly stations, semiconductor handling equipment, and other compact machines that require fast response. Its small format makes it useful where the available installation space is limited but repeatable servo performance is still required.
The motor provides a continuous stall torque of 0.60 Nm, which is suitable for direct coupling to light inertial loads without added gearing. Its maximum speed is 10,000 rpm, allowing rapid positioning cycles in compact machinery and short move times between indexing points. A centering pilot of 40 mm supports accurate alignment with reducers or couplings, and the service connections exit on the right side through a connecting cable with a coupling unit for straightforward connection. The size 025 frame with length code B keeps the housing short and helps reduce moment load on the surrounding machine structure.
The rotor and flange use standard dynamic balancing, which helps reduce vibration during high-speed operation and supports smoother running at elevated shaft speeds. The motor is supplied without a blocking brake, so holding torque during power loss must come from the drive or an external device. Position feedback is provided through resolver feedback, and the output uses a keyway shaft for common coupling arrangements in light-duty servo axes. The motor is also supplied without a shaft seal, so it is better suited for clean, dry environments, and the single-ended shaft layout keeps the package compact.
