Abstract
An axial air-gap motor stator and a fan thereof includes a motor stator. The motor stator includes multiple metal substrates stacked together. Each metal substrate has a port and multiple pole teeth disposed around the port. The two adjacent pole teeth on each metal substrate are disposed with a magnetic pole and the number of the pole teeth of each metal substrate is a natural number twice the number of the magnetic poles of each metal substrate. The magnetic poles of the metal substrates are arranged in a staggered manner. This avoids the problems of interference of magnetic poles and prevents the magnetic field from being affected.
