Abstract
An electric motor includes an upper housing, a lower housing including a flange for mounting the upper housing thereon and a cone-shaped portion extending away from the flange and the upper housing. The electric motor further includes a stator assembly formed of a first core having a first height and fitted into the upper housing, a rotor assembly rigidly joined to a shaft to rotate therewith in the stator assembly and formed of a second core having a second height, and a hub connected to a lower end of the shaft to rotate therewith in relation to the cone-shaped portion. The hub is configured to secure an operable implement to the electric motor. The second height is greater than the first height.
