Improved magnetic palastro, for induction motors, of the type in which each protruding pole is grooved, so that a portion of its pole piece is able to be surrounded by a short-circuited winding or shadow coil, essentially characterized by being together to each main salient pole a secondary salient pole, destined to receive a part of the turns of the main pole, originating a field of smaller amplitude than the main pole, and providing a greater smoothness in the passage from a maximum of positive induction to a maximum of negative induction.
