<p>The proposed induction motor comprises a permanent magnet rotor and a stator which is electromagnetically energized by an alternating field. Between a rotatingly free inner part (16) of the permanent magnet rotor and the stator poles (11, 12) there is arranged an electrically conducting outer part (17) of the rotor, which outer part is configured as a hollow cylinder or as a squirrel cage. After the starting of the permanent magnet inner part (16) which permanently synchronously rotates, the rotor outer part (17) rotates asynchronously like a squirrel cage armature and drives the load which is connected thereto. A blocking device (36, 37) of the rotation direction provides a determined rotational direction of the drive shaft (27).</p> |
