Fractional-horsepower Motor
A fractional-horsepower motor (FHP) is an electric motor with a rated output power of less than (the term 'fractional' indicates less than one unit). There is no defined minimum output, however, it is generally accepted that a motor with a frame size of less than 35mm square can be referred to as a 'micro-motor'. Fractional-horsepower electric motors are exempt from the US Energy Policy Act of 2005 and the new EN 60034-30:2009 ruling of European directive 2005/32/EC concerning the efficiency classes of low-voltage three-phase asynchronous motors. History The earliest commercially successful electric motors date back to the latter part of the 19th century when Nikola Tesla patented his induction motor in 1888. The development of fractional-horsepower motors, however, would not have taken place without the push toward urban, and later, rural electrification, using alternating current. Electrification began in cities around 1900, and Chester Beach, an employee of Hamilton-Beach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
