ABSTRACT:
The present invention concerns an electromagnetic motor of the type including a stator (4), a rotor (6) mounted for rotation relative to the stator, and a cage (2a, 2b, 2c, 2d, 2e) fixedly engaged relative to the stator, such cage including a bottom (18), a cover (22) and a body (20), the rotor being mounted for rotation in the interior of the cage, such motor being characterized in that the cage (2a, 2b, 2c, 2d, 2e) is formed from a synthetic material, while mechanical anchoring and positioning means are provided between the wall (P) of the cage body (20) and the stator (4) which leave the wall (P) free. This motor is intended for fitting out a timepiece in particular.
