  • Rectifier commutation in electrical machines
    Patent number: 4598241
    Abstract: In electrical machines with commutators, installing diodes and controlled rectifiers right into the electromechanical structure of armatureseliminates sparking of the commutators, and alsoallows the design of AC-fed motors having the characteristics of DC motors, including the capability to return power to the AC line while being overdriven.Use of controlled rectifiers permits to eliminate the mechanical commutator itself; the controlled rectifiers assume the commutation process utilized by the invention, wherein there is a cooperation between rectifiers and armature coils undergoing commutation.
