Abstract: A method for winding a coil for electric machines, and a coil wound according to this method. Wherein the method comprises the following steps: placing a wire against a form, leaving a first length of the wire and a second length of the wire extending from the form, wherein the first length has a first end and the second length has a second end; winding the first length in a first direction round the form, such that the first end of the first length is ending in an outer layer of the plurality of layers; winding the second length in a second direction round the form, wherein the second direction is opposite the first direction, wherein the second end of the second length is ending in an outer layer of the plurality of layers, wherein all layers and levels of the coil are filled.

Abstract: Arrangement at an electric machine, particularly motor, generator, or actuator, with a stator with teeth (11, 12) carrying coils (15), particularly one layer, for concentrated windings. A permanent magnetic rotor is movable relatively to the stator (11, 12). The teeth of the stator are arranged for receiving coils (15) with generally rectangular opening. Advantages are achieved if the stator teeth (11, 12) are provided to receive generally identical coils (15) closing the grooves (14, 16). The teeth (11, 12) may be alternating rectangular and converging/diverging toward the top, to provide grooves (14, 16), with parallel sides to enter the coils (15). The converging teeth (22) have preferably a shortened top (23). The grooves are preferably provided to make room for a semi magnetic groove wedge (17, 18) between adjacent teeth.
