1916 Owen Magnetic at Crawford Museum. The first Owen Magnetic was introduced at the 1915 New York auto show when Justus B. Entz's electric transmission was fitted to the Owen automobile: "R.M. Owen have leased the large new three story fireproof building at the corner of Fifth avenue and One Hundred and Forty-second street, New York, where they will build the new Owen Magnetic motor cars."
Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
In the late 19th century and early 20th century, some of the earliest locomotives and cars used direct drive transmissions at higher speeds. [ 5 ] [ 6 ] Direct-drive mechanisms for industrial arms began to be possible in the 1980s, with the use of rare-earth magnetic materials . [ 1 ]
[4] [5] A popular example of a magnet motor, although without rotating axis, was put forward by John Wilkins in 1670: A ramp with a magnet at the top, which pulled a metal ball up the ramp. Near the magnet was a small hole that was supposed to allow the ball to drop under the ramp and return to the bottom, where a flap allowed it to return to ...
DC motors can operate directly from rechargeable batteries, providing the motive power for the first electric vehicles and today's hybrid cars and electric cars as well as driving a host of cordless tools. Today DC motors are still found in applications as small as toys and disk drives, or in large sizes to operate steel rolling mills and paper ...
1995: Oldsmobile introduced the first GPS navigation system available in a United States production car, called GuideStar. [20] The navigation system was developed in cooperation with Zexel. Zexel partnered with Avis Car Rental to make the system widely available in rental cars. This provided many in the United States general public with their ...

The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology. The schematic shows a permanent magnet motor with stationary magnets outside of a brushed armature (a type commonly used on toy slot-cars).
