Abstract
A motor and a fan are provided. The motor has a stator assembly, two mutually independent rotor assemblies, and two mutually independent rotating shaft assemblies. The stator assembly has a stator core and two groups of mutually independent windings. The rotor assemblies are oppositely and coaxially arranged on two axial sides of the stator assembly and form an axial air gap with the stator assembly. The two rotor assemblies are configured to rotate independently. The two mutually independent rotating shaft assemblies are coaxially connected with the two rotor assemblies, respectively, and protrude in a direction of the same side away from the stator core along the axial direction of the motor.
