A motor includes a rotor magnetic ring, a stator core, a first magnetic conducting sheet and a second magnetic conducting sheet. The stator core is disposed around and out of the rotor magnetic ring. The first magnetic conducting sheet has a ring shape with a protruding portion serving as a first magnetic pole. The second magnetic conducting sheet has a ring shape with a protruding portion serving as a second magnetic pole. The first magnetic conducting sheet is disposed at the upper side of the stator core, and the second magnetic conducting sheet is disposed at the lower side of the stator core. The projections of the first and second magnetic poles alternate with each other. A fan including the motor is also disclosed.

Fan and motor thereof

A balancing cover connected with a rotor structure includes a plate, a plurality of blades and at least one balancing element. A central portion of the plate has an opening. Each blade has one end connected with the plate and mounted on a circumference of the opening, and the other end connected with the rotor structure. Each blade has at least one hole, in which the balancing element is disposed.

Pump and balancing cover thereof

A fan includes an inner rotor motor, which includes a housing, a rotor assembly and a stator assembly. The rotor assembly includes a rotor, which includes blades and is accommodated in the housing. The stator assembly is disposed in the housing corresponding to the rotor assembly. The stator assembly includes a coil disposed around the rotor. The coil is a flat helix structure formed by a continuous wire, and the flat helix structure forms a cylindrical plane perpendicular to a radius plane of the motor.
