<p>Low cost motors including specifically two pole (1, 51 and 101) and four pole (201, 251, 278 and 301) motors are provided with magnetically conductive stacked laminations (3 and 203) each having a multi-pole portion with a rotor opening (9 and 209) and spaced and adjacent side legs (7, 7 and 207, 207) extending from circumferentially spaced areas of said multi-pole portion. Each side leg (7, 7 and 207, 207) terminates in an outer free extremity. The combined stacked laminations (3 and 203) provide stacked and adjacent side legs (7, 7 and 207, 207) in circumferentially spaced areas of stacked multi-pole portions with aligned rotor openings (9 and 209) for receiving a rotor (22 and 211). Each of the stacked side legs (7, 7 and 207, 207) having a combined predetermined outer cross-sectional coil winding area (27, 27 and 227, 227) and an electrically conductive coil (35 and 335) is positioned about the coil winding area (27, 27 and 227, 227) of the stacked side legs (7, 7 and 207, 207). Separate magnetically conductive stacked laminations (37 and 237) are provided for attachment to the outer free extremities of the spaced and adjacent stacked side legs (7, 7 and 207, 207). At least one of the separate magnetically conductive stacked laminations (37 and 237) are configured, arranged and dimensioned to be positioned between the spaced and adjacent side legs (7, 7 and 207, 207) during the forming of the laminations.</p> |
