Electric motors are round. Wheels are round. It's a pretty natural impulse to combine the two. No lesser automotive luminary than Dr. Ferdinand Porsche did it first, inventing the wheel-hub motor in ...

In-hub wheel motors are among the most tantalizing and yet elusive of electric-vehicle technologies. And now, after decades of failures and near-misses, a donut-shaped electric hub motor was among the ...

Ferdinand Porsche, it seems, was always ahead of the curve. He conceived one of the earliest electric cars back in 1900, which later added a gas engine to compensate for its primitive lead batteries.

An electric wheel hub drive is an assembly that typically consists of an electric motor and braking assembly - all of which is attached to a vehicle's suspension and often fits within the confines of ...

New in-wheel motor systems modify the hub of each electric-vehicle (EV) wheel by adding a complete drivetrain that supplies torque to its associated tire (Fig. 1). Also included with these in-wheel ...

This file type includes high resolution graphics and schematics when applicapable. In-hub motors are traction motors in that they change rotary motion to linear motion. They are actually a special ...
