MDD025A-N-100-N2K-040MB0
The MDD025A-N-100-N2K-040MB0 is a permanent-magnet synchronous motor in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides fast and accurately regulated rotary motion for compact automation axes such as small pick-and-place units or miniature spindle stations. The motor follows the modular layout used in this series, which helps it fit into tight machine spaces while still supporting internal position measurement through its integrated absolute encoder. This combination makes the unit suitable for applications that need compact dimensions, responsive motion, and dependable closed-loop control.
The motor delivers a continuous standstill torque of 0.33 Nm, so it can hold that load at zero speed without exceeding its thermal limits. During normal operation, it reaches a nominal speed of 10000 rpm, allowing high surface or linear speeds when the driven mechanism uses an appropriate transmission ratio. A centering diameter of 40 mm provides the pilot fit for accurate alignment with the machine housing. Electrical power and feedback pass through a single connector on side B, which helps keep cable routing compact in restricted spaces. Dynamic balance is rated as Standard, which helps limit vibration as the rotor accelerates and runs at high speed.
A shaft with a keyway transmits torque to couplings without slip, and the frame size code 025 identifies a compact stator diameter suited to lightweight tooling. Position data returns to the drive through resolver feedback, providing analog signals that support stable closed-loop operation in electrically noisy environments. The motor is supplied without a blocking brake, so any holding function at standstill must be provided by the drive or by external machine hardware. Motor length code A keeps the housing short, and the standard uncooled layout avoids the need for separate cooling hardware. Because the motor does not include a shaft seal, it should be installed in a clean area that is protected from liquid contaminants.
