The wheel motor (also called wheel hub motor or hub motor) is an electric motor that is incorporated into a wheel and drives it directly.
Compared with the conventional electric car (EV) design with one motor situated centrally driving two (sometimes four) wheels by axles, the wheel motor arrangement has certain advantages and disadvantages. First the disadvantages:
Then the advantages:
The electric wheel hub motor was raced by engineer
Ferdinand Porsche in
1897 in
Vienna,
Austria. Porsche later became famous for designing Hitler's "peoples car" the Volkswagen and later the sportscar that bears his name -Porsche.
Porsche's first engineering training was electrical not internal combustion based. As a result he developed his first cars as electric cars with electric wheel hub motors that ran on batteries . The Lohner Porsche, fitted with one wheel motor in each of the front wheels, appeared at the World Exhibition in Paris in 1900 and created a sensation in the young automobile world. In the following years, 300 Lohne Porsches were made and sold to wealthy buyers.
Porsche recognized the efficiencies of power transmission of the electric wheel hub motor over a central engine driving a transmission then the wheels. In an effort to overcome the low battery capacities of the day, he developed a electrical wheel hub motor car that got its electric power from a gasoline driven generator in the car effectively inventing the hybrid auto he called the "System Mixt". He set many speed records of the day in this gasoline powered generator car with two front wheel electric hub motors. He won Austria's Automotive Engineering prize with that car and his career took off. Eventually the growth in power of the gasoline engine overtook the power of the electric wheel hub motors and this made up for any losses through a transmission. As a result autos moved to gas engines with transmissions however they were never as efficient as electric wheel hub motors.
