AC or DC electric motor when converting from gasoline to an all electric car.

by Admin on August 6, 2011

When converting an older gas burner to the newer, all electric power plant you certainly have options. One of the first questions to answer is, “Will I use an AC or DC electric motor?”

There are many different advantages and disadvantages to using the DC versus the AC motor when converting a car to all electric. The most popular motor being purchased is the DC since it tends to be less expensive, all around, than its AC counterpart. For somewhere between $3,000 and $5,000 you can purchase a kit for converting to DC motor (price quoted does not include battery which can run between $2,000-$3,000). The AC version of the electric motor can begin somewhere around $10,000 and increase substantially from there, making it the obviously more expensive choice. Keep in mind that the weight and size of the vehicle being converted will play a large part in how much power you will need when planning to commute on the freeway.

Beginners will be glad to find that customized kits have been made available and are built specifically for many different model vehicles we are used to seeing on the road today. With a little research you can find all electric cars for sale that have already been converted. The DC version enjoys the standard “golf cart style” 6V or 8V battery, which is wired to provide the voltage necessary to perform. You will really benefit from the ease of the conversion when using these customized kits. The list of vehicles for which these kits are available is limited and includes the Volkswagen Rabbit, Porsche 914, Chevy S-10, Geo Metro and possibly a few others.

People often ask right out, “Why do most people choose to go with the DC motor conversion versus the AC motor conversion?” They are looking still for an outright answer. My answer to them would have to be, obviously, price, ease, fun, and convenience. This would fall more into the project car you could have a lot of fun doing while helping our environment.

It seems the obvious choice for cars of the future to be AC powered. They are capable of more miles per charge due to better efficiency and the added benefit of regenerative braking that is easily built in to the AC version. The DC counterpart is much more affordable and could make a great project that could end up saving you a lot of money in fuel expenses while participating in making the world a cleaner place to live.

Assuming you have plenty of money, the AC electric motor for your all electric car conversion would be the way to go. If you are like me and a hobbyist that is experimenting and having fun doing it, the much less expensive way to go is with the DC motors.

Washing an all electric car. I have heard the question a few times of can I wash my electric car without worries like my old gas burner. The answer is of course. Especially when you are just washing it in the driveway. You may have problems with automatic car wash equipment if it sprays under the car. Other than that I see no problems as long as you use basic safety precautions.
