Patent ID: 7939984

Claim:
A motor, comprising: a stator including (i) an outer section which defines a center, and (ii) a set of teeth coupled to the outer section, each tooth of the set of teeth extending from the outer section toward the center defined by the outer section, each tooth having (i) a first end which is proximate to the outer section and distal to the center, and (ii) a second end which is proximate to the center and distal to the outer section, a width of the first end of each tooth being substantially greater than a width of the second end of each tooth; a rotor arranged to rotate relative to the stator, the rotor including a set of permanent magnets, the number of permanent magnets in the set of permanent magnets being at least two; the set of teeth defining a maximum rotor diameter; and the outer section defining a stator diameter which is at least twice as large as the maximum rotor diameter, each tooth narrowing from the outer section toward the center, the second end of each tooth being substantially shoeless; and the set of teeth defining a uniform tooth profile and a uniform slot profile, the uniform slot profile being arranged to accommodate windings, and the uniform tooth profile having a larger area than the uniform slot profile; wherein portions of the windings accommodated in the uniform slot profile are arranged in rows and columns, wherein the number of rows is at least two, and the number of columns is at least two.
