Remy International had its beginnings in 1896 when Frank and Perry Remy opened a home wiring business in Anderson, Indiana. In 1901 the Remy Electric Company was incorporated. Perry Remy had conducted experiments with magneto and by 1910 the company was producing 50,000 magnetos a year.
To prove the dependability of their product, the Remy brothers sent two men on a 6,000-mile (9,700 km) journey in 1909. They drove a Remy equipped Buick on a ten week trip from the hills of Kentucky to the swamps of Florida.
The Remy brothers sold their firm to Staughton Fletcher, Jr. and the Fletcher Savings and Trust in 1911 for a reputed one million dollars. Fletcher expanded the product line to include cranking motors, generators, and distributors.
Remy's competition was Dayton Engineering and Laboratories Company(Delco) under the leadership of Charles F. Kettering. Kettering also manufactured ignition equipment and generators.
The United Motor Company purchased the two competitors in 1916 and incorporated them into their operations. The companies remained separated until purchased by General Motors two years later.
In 1918, Delco Remy began operating as a division of General Motors, developing advanced technologies and providing the industry with automotive, heavy duty, and U.S. military products. A successful General Motors division for more than 75 years, Delco Remy became its own entity in 1994 when a group of private investors bought the heavy duty and automotive divisions.
In 2004 the company changed its name to Remy International, Inc. Today, Remy is the leading global manufacturer and remanufacturer of automotive parts, including starters, alternators, and hybrid motors.
Remy International's heavy duty products are sold under the Delco Remy brand which is licensed from General Motors. As of 2014, only starters and alternators are manufactured and sold under the Delco Remy brand name. The company sells products as components for new vehicle production in addition replacement units and parts through various distributors and Original Equipment dealerships.
There are now two main types of heavy duty alternators produced by Remy International. The first being a typical brush-style alternator, in addition to a brushless type design. The brushless type design contains fewer moving parts making the unit more durable and increasing overall life in addition to an increase in efficiency. Examples of current brushless products include 36SI, 40SI, and 55SI. Current examples of brush style alternators include 24SI and 28SI.
