ABSTRACT:
In this electric motor and tachometric generator unit the generator comprises a rotor secured to the motor shaft and provided with a set of permanent magnets, and a fixed armature incorporating an armature winding. The commutation of the generator and motor windings is controlled by a coder via an electronic commutation circuit. The generator rotor is disc-shaped and the magnetic axes of the permanent magnets are parallel to the shaft. The movable portion of the coder is the generator rotor cooperating with a set of fixed magnetic sensors, preferably of the Hall type, mounted on one side of the generator rotor, the fixed armature being mounted on the other side of this rotor.
