Abstract
An improved electric motor having a commutator and brushes incorporates a fluid comprising one or more stable halogenated aliphatic hydrocarbons which is liquid from ambient temperatures up to about 150.degree. F., and means for applying said fluid continuously to brushes adjacent said commutator while the apparatus is running.
Claims31
An electric rotary apparatus comprising:
- a commutator and brushes,
- a fluid comprising one or more stable halogenated aliphatic hydrocarbons which is liquid from ambient temperatures up to about 150.degree. F., and
- means for applying said fluid continuously to said brushes adjacent said commutator while said apparatus is running.
A method for increasing the efficiency of electric rotary apparatus of the type having a commutator and brushes comprising the steps of:
- a) providing a fluid comprising one or more halogenated aliphatic hydrocarbons which are stable liquids from ambient temperatures up to about 150.degree. F., and
- b) continuously bathing an area of said brushes adjacent said commutator with said fluid while said apparatus is running.
In an apparatus having rotating components;
- an improvement comprising:
- a source of at least one liquid comprising one or more halogenated aliphatic hydrocarbons having between one and twelve carbon atoms,
- means for applying said liquid to said components in a substantially continuous manner while said apparatus is running, and
- means for recovering and reusing said liquid in said applying means.
