An electric car uses an electric motor for propulsion and is the best known alternative to expensive gasoline driven vehicles. The electric car motor makes use of electrical energy to produce mechanical energy, or in other words movement. Electric motors make use of the electrical energy to rotate and anything attached to the motor automatically harnesses that rotating movement. Electric motors are not only limited to cars, you can find the smallest ones in watches and the largest ones are used to propel ships.
The electric car motor involves rotating coils of wire driven by a magnetic force that is exerted by a magnetic field on electric current. This is how electrical energy is transformed into mechanical energy.
The principle behind alternating current or the AC motor is that every single second it is changing direction of the flow several times. For this reason the current that runs through the electromagnet is AC, with the north and south poles on the electromagnet alternating as well. This keeps the electromagnet spinning.
The DC electric car motor is actually a very good one and the Advanced Series is a best seller. However you will need to consider the following carefully before you opt for a DC motor for your car. Will you need to carry heavy loads and go up hill frequently? If the answer to both is yes, then you will be better off choosing an electric AC motor.
If on the other hand these are not really important concerns, then a DC motor will be a good choice. They provide very good torque right from the start and give the driver a good smooth ride.
Remember that with the electric car motor you definitely get what you pay for, so research well and seek the advice of a professional before you make a final decision. Electric motors are not cheap and you cannot just go out and buy another if you make a mistake, it will prove to be a very costly mistake!
