MICROMO's 2-phase miniature stepper motors are constructed with two different technologies. The AM series motors are constructed with a patented technology allowing for maximum power in a small package. The rotor is designed using NdFeB magnets placed equidistantly on the rotor hub. The ADM series motors are constructed with a magnetized disk magnet hub. Both designs reduce the number of components needed for assembly and provide for high reliability and outstanding shock and vibration resistance. These unique miniature stepper motor designs result in a reliable, powerful, and quiet motor in a very small size.
