Electric motors for your electric car

When selecting an electric car motor you have two choices. DC or AC electric motors. DC motors are powered by Direct Current (a battery is an example of direct current) you will need to find what is called a series wound DC Motor. Most DC motors operate from 96 to 192 volts.

AC Motors work off of Alternating Current. AC motors suitable for an electric car are usually three-phase 240VAC types, requiring a 300 volt battery pack.

DC motors have advantages over AC motors in cost and battery pack voltages. Since the DC motor runs at a lower voltage than the AC motor you can use the 6 volt golf cart style of battery. They do require more current than their AC counterparts but the 6v battery happens to have the best capacity rating so this should not be a problem. AC motors, although costing more, do have distinct advantages over the DC motor. For one, they can use the back emf from the motor while the car is braking to recharge the batteries. This causes the AC motor to be more efficient Although they require a higher battery pack voltage, around 300 volts, they use less current than the DC motor and therefore can use the lower capacity 12 volt batteries for their battery pack.

Both types of motors need a motor controller to operate, and once again due to the complexities involved, an AC motor controller is much more expensive than a comparable DC motor controller. Many times you can find very inexpensive sources of motors by shopping around. Due to regular maintenance schedules many industrial areas will have businesses that throw out working motors on a routine basis, which could be a gold mine if you can find and talk to the right person in charge.

Another great source is eBay. Just go to eBay and do a search for DC or AC motor, and you will find many sources to choose from. When selecting an electric car motor you need to do your homework. Many factors come into play such as cost, type of car you are converting, and don’t forget about how much space you have under the hood. Proper planning goes a long way for a successful electric car conversion.

Homemade Power Plant – Make Your Magnetic Motor

Have you ever wanted to make your own electricity? A home made power plant can be a fun and educational project that helps to reduce monthly expenses. With just a few items and a little patience you can build your magnet motor.

A magnetic generator is an electromechanical device that creates an electric current from mechanical motion. A coil of tightly wrapped wires, surrounds a series of magnets that are free to rotate about an axis in the middle of the coil. In the presence of a changing magnetic field, called flux, an electromotive current is produced that can power electric devices. The type of current produced is Alternating Current and is the class found in any home outlet.

A person can either choose to physically design the alternator/generator, or can use an existing one and install it within a production and storage system that is designed by the user. This can be done inexpensively and with a little patience.

The electric current comes from the changing magnetic field as a result of the spinning magnetic core in the alternator. Similarly, some people may opt to use a dynamo to produce direct current. This would necessitate an inverter to change the type of current for everyday use. Any thing can be used as the mechanical drive, whether bicycle or windmill, if it turns the shaft should work.

For the purposes of most common electronics alternating current (AC) is favored as it is the common type of power available in houses. Power stored in a battery is available to use only as direct current (DC). In this case an inverter needs to be installed that converts DC current to AC current.

To feed the generated power back into the power grid, the battery bank must be wired to the house fuse box. This can be a dangerous job if the person is not experience in electric work. For this part it may be a good idea to seek a professional electrician. The benefit of this work, is that you can actually sell the excess power generated back to the local power company.

A magnetic energy generator, more appropriately called an electric generator, can help you be a part of the green economy. In addition can prove to be educational experience that sheds light on how technology works. A person should do their homework before starting this project and consult a professional when necessary.
