A brushless a-c motor (BACM) (10) consisting of a non-conductive stator (12) and a rotor (44). The rotor (44) has an outer surface (50), a right surface (34) and a left intermediate surface (16) from where extends a protrusion (20) having a cavity (26) into which is inserted a motor support rod (38). The stator (12) includes a multiplicity of longitudinally extending wiring notches (36) and on the left intermediate surface (16) and the right surface (34) are wire attachment structures (18). Around and between the structures (18) and the notches (36) is wound a multiplicity of insulated wires (32) that terminate at an a-c power source (180). The rotor (44) has an inner surface (48) that has longitudinally attached a multiplicity of magnets (56) and is attached to a bearing (80) that is attached to the central protrusion (20). To operate the BACM (10), one end of a circular belt (98) is placed around the rotor (44) and the opposite end is inserted over a work piece.
