A shaft encoder is made from a stator cage (7), upper (6) and lower (5) rotor cages all open at the bottom and a ring magnet (4) magnetized axially and set inside the upper rotor cage. The stator cage is fastened in a casing (1) unable to twist. The rotor cages and the ring magnet cannot twist and are fastened on an axle shaft (3) able to slide and turn on bearings in the casing. All cages have bars (14,15,24,25) running axially and aligned to each other. |
