Patent ID: 7687959

Claim:
A brushless a-c motor ( 10 ) comprising: a) a circular stator ( 12 ) made of plastic and having: (1) an outer surface ( 14 ) having a multiplicity of longitudinally extending wiring notches ( 36 ), (2) a left intermediate surface ( 16 ) from where extends a multiplicity 10 of wire attachment structures ( 18 ) and an integral central protrusion ( 20 ) and (3) a right surface ( 34 ) from where extends a multiplicity of wire attachment structures ( 18 ), wherein around and between the attachment structures ( 18 ) and inserted into the longitudinal wiring notches ( 36 ) is a multiplicity of insulated wires ( 32 ) that are wound parallel to the longitudinal axis of said stator ( 12 ), wherein the ends of the wires ( 32 ) exit the motor ( 10 ) and terminate at an a-c power source ( 180 ), b) a circular rotor ( 44 ) that is dimensioned to rotate around the outer surface ( 14 ) of said circular stator ( 12 ), said rotor ( 44 ) having: (1) an inner surface ( 48 ) having longitudinally attached thereto a multiplicity of permanent magnets that are equally spaced with alternating north (N) and south (S) poles, (2) an outer surface ( 50 ), (3) a right edge ( 52 ), (4) a left edge ( 54 ), (5) a right circular cooling plate ( 64 ) that is attached to the right edge ( 52 ) of said circular rotor ( 44 ), and (6) a left circular plate ( 74 ) having a perimeter edge ( 76 ) that is spaced from the inner surface ( 48 ) of the cylindrical cylinder ( 46 ) and having a centered bore ( 78 ) that is dimensioned to be attached over the central protrusion ( 20 ) located on said stator, c) a bearing ( 80 ) having a perimeter edge ( 82 ) that interfaces faith the inner surface ( 48 ) of said rotor ( 44 ), and d) a circular belt ( 98 ) having a first end that is wound around the outer surface ( 50 ) of said circular rotor ( 44 ), and a second end that is wound around a rotating work piece.
