Protean Continues Campaign for In-Wheel Electric Motors

Why is it that some of the best ideas for automotive efficiency never reach the market? For example, the concept of putting electric motors directly into wheels has been proposed many times over the years—but has not yet seen the light of day. The latest company to give it a go is Protean Electric. The company is showing off its technology in the form of a Vauxhall Vivaro hybrid truck this week at the Center for Automotive Research Management Briefing Seminar in Traverse City, Mich.

Protean claims that the in-wheel motor approach could improve the efficiency of a hybrid by 300 percent, and allow for relatively easy conversion of gas-powered cars into hybrids. Each motor weighs about 70 pounds and offers 110 horsepower. The motors could provide the capacity to drive purely on electricity, as well as assist the gas engine or remain dormant.

The company claims the product will be ready for mass production as soon as 2012. But take a look at the long list of other concepts using in-wheel motors that are still sitting on the shelves of R& D departments.

Michelin Active Wheel

The Michelin tire company has been showing off versions of the “Active Wheel” since 2004. The system contains virtually all of the components necessary for a vehicle to propel or stop: an electric motor, suspension coils and springs, and braking components. The only thing missing is the source of energy.

Fed by lithium ion batteries or fuel cells, the Active Wheel’s electric motor will output 30 kilowatts of power—per wheel that is. Vehicles using this system can be configured with two Active Wheels up front, or one at each corner.This allows manufacturers to offer two configurations with two and four wheel drive. Michelin presented two vehicles, and the Venturi Volage Hueliz Will, using the Active Wheel Motor Show 2008 in Paris.

Venturi Volage

The Michelin Guide-Orange Heuliez concept also uses the Michelin Active Wheel. This is a front-wheel drive all-electric vehicle that seats five trunks, and features front and rear. Drivers will be able to choose from four different packages wheel with driving ranges of 100 to 250 miles. The will was scheduled for production in France in 2010, but is now in the category to be determined.

Lohner-Porsche Elektromobil

The Paris Exposition of 1900 featured the Lohner-Porsche Elektromobil, which would later become one of the first hybrid cars. It was designed two years earlier by a 23-year-old engineer, unknown at the time, named Ferdinand Porsche. Exposition records show that Porsche’s vehicle could travel 38 miles solely on electricity. Porsche integrated battery-powered electric motors directly into the front wheel hubs, producing one of the first front-wheel drive cars. He later added an internal combustion gasoline engine to drive a generator, which charged the batteries.

Electric Vehicle Conversion – DIY Electric Car Conversion From ...

Since the engine is gone, other supporting components such as radiator, fuel lines, exhaust pipes and gas tank have no purpose anymore hence can be removed as well. To power the electric motor, a DIY electric car would need 15 – 20 units of deep cycle batteries. Deep cycle batteries are usually used on marine boats and they are perfect for EV. An electric vehicle conversion project is simple for those who understand the technical aspects of an automobile. If you have never done any car repairs or maintenance before, then a DIY electric car conversion project many not be a good idea for you. Your best option is to outsource the entire retrofitting work to a professional mechanic. Doing so will save you a lot of time and headache.
