Abstract
Methods for repairing electric machines, such as wind generators, and stators implemented thereof. One method includes replacing a first stator core with a second stator core, wherein the second stator core has fewer stator slots than the first stator core, and wherein the stator slots are configured to receive coil windings. The method includes increasing a number of coil turns forming each coil winding from a first value to a second value, wherein the first value is associated with the first stator core and the second value is associated with the second stator core. The electric machine with the second stator core has rated power output at least as high as the electric machine with the first stator core.
