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.
