Here in the U.S., the first successful electric car made its debut around 1890 thanks to William Morrison, a chemist who lived in Des Moines, Iowa. His six-passenger vehicle capable of a top speed of 14 miles per hour was little more than an electrified wagon, but it helped spark interest in electric vehicles.
Over the next few years, electric vehicles from different automakers began popping up across the U.S. New York City even had a fleet of more than 60 electric taxis. By 1900, electric cars were at their heyday, accounting for around a third of all vehicles on the road. During the next 10 years, they continued to show strong sales.
To understand the popularity of electric vehicles circa 1900, it is also important to understand the development of the personal vehicle and the other options available. At the turn of the 20th century, the horse was still the primary mode of transportation. But as Americans became more prosperous, they turned to the newly invented motor vehicle -- available in steam, gasoline or electric versions -- to get around.
Other developments also contributed to the decline of the electric vehicle. By the 1920s, the U.S. had a better system of roads connecting cities, and Americans wanted to get out and explore. With the discovery of Texas crude oil, gas became cheap and readily available for rural Americans, and filling stations began popping up across the country. In comparison, very few Americans outside of cities had electricity at that time. In the end, electric vehicles all but disappeared by 1935.
Over the next 30 years or so, electric vehicles entered a sort of dark ages with little advancement in the technology. Cheap, abundant gasoline and continued improvement in the internal combustion engine hampered demand for alternative fuel vehicles.
Fast forward again -- this time to the 1990s. In the 20 years since the long gas lines of the 1970s, interest in electric vehicles had mostly died down. But new federal and state regulations begin to change things. The passage of the 1990 Clean Air Act Amendment and the 1992 Energy Policy Act -- plus new transportation emissions regulations issued by the California Air Resources Board -- helped create a renewed interest in electric vehicles in the U.S.
During this time, automakers began modifying some of their popular vehicle models into electric vehicles. This meant that electric vehicles now achieved speeds and performance much closer to gasoline-powered vehicles, and many of them had a range of 60 miles.
Consumers now have more choices than ever when it comes to buying an electric vehicle. Today, there are 23 plug-in electric and 36 hybrid models available in a variety of sizes -- from the two-passenger Smart ED to the midsized Ford C-Max Energi to the BMW i3 luxury SUV. As gasoline prices continue to rise and the prices on electric vehicles continue to drop, electric vehicles are gaining in popularity -- with more than 234,000 plug-in electric vehicles and 3.3 million hybrids on the road in the U.S. today.
Part Presentation Slides offer a cost and space saving alternative to feed conveyors. Utilizing electric actuators, they deliver a 90% reduction in energy usage compared to long stroke pneumatic slides. Constructed of heavy duty aluminum extrusion, slides are suitable for harsh environments. A single motor unit can drive one or two carriages. Dual slide units allow push/pull presentation, which buries load time in the cycle. Slides can be outfitted with trays for multiple presentations. Floor mounted slides can pull dunnage carts.
AES series part presentation slides are available in four styles: Single, Double, Double Independent, and Push-Pull. Double provides a single carriage plate, allowing for the largest load. Double Independent's two motors move carriage plates independently of each other. Push-Pull's single motor moves two carriage plates in opposing directions.
AES slides are screw drive units with VFD or servo motor.
The new MES is a mini version of Welker's standard part presentation slide, for light duty applications. Belt-drive operation with servo actuator, or customer supplied motor. Alignment pin provided for homing verification.
Installed program conventions: Forward is away from motor. All prox cables must be active to run shuttle. Use extreme caution and slow speed when using laptop controlled jog mode. The switches will be disabled and over-travel crash is possible.
