Stator structure of motor

A stator structure of a motor includes a stack of at least one first silicon steel plate and at least one second silicon steel plate. Each silicon steel plate has a plurality of radial arms and pole teeth formed on ends of the radial arms, and each pole tooth stretches to have a first and a second s...

Summary:A stator structure of a motor includes a stack of at least one first silicon steel plate and at least one second silicon steel plate. Each silicon steel plate has a plurality of radial arms and pole teeth formed on ends of the radial arms, and each pole tooth stretches to have a first and a second side portions symmetry with respect to the extending direction of each radial arm. The second silicon steel plate differs from the first one in that its pole teeth are formed with cuts on the first side portions, and all silicon steel plates are stacked in a manner that the magnetic center of a rotor relative to a pole tooth is closer to the second side portion than the first one.
