These motors are suitable for many uses because of their low cost. Brushed DC motors are widely used in electric vehicles for retracting, positioning and extending electrically-powered side windows. In addition, more torque is generated from DC motors that lead to a cost-cutting aspect.ĭC motors are classified into three categories namely brushed DC motor, BLDC or brushless DC motor, and stepper. In a majority of the cases, a DC motor runs on anything that lies between 96 and 192 volts. PM motors offer an array of advantages of induction motors including higher efficiency, high torque and power density, high torque at low speed, and compact and low weight. In synchronous motors, the rotor turns at the same speed as that of the rotating magnetic field unlike an induction motor where it turns at a lower speed than that of the field. Because of its simple design, induction motors don’t require high maintenance. The control of these motors is quite simple to implement. Induction motors are considered the most cost-effective and reliable ones among the industry. AC motors can be divided into two main categories namely asynchronous motor or induction motor and synchronous motor or PM motor. Put simply, upon interaction of the magnets, the shaft, together with the coil of wires, starts to rotate, thus operating the motor. When the coil of wire is supplied with an electric (AC) charge, it becomes an electromagnet, thus creating a magnetic field. An AC motor comes with a coil of wire together with two fixed magnets that surround a shaft. The fundamental operation of these motors depends on the principles of magnetism. Even though AC motors are more expensive than DC motors, they’re widely popular among electric auto manufacturers, especially when it comes to high-performance vehicles. When it comes to performance on road, electric cars with AC motors can run more smoothly at rougher terrains, apart from offering more acceleration.

The regenerative feature of AC motors can also work as a generator which brings power back to the battery of an electric vehicle. AC motors in electric vehiclesĪn AC motor is powered by alternating current and is likely to be a three-phase motor that can function at 240 volts AC.
On the flip side, as these motors are provided electricity by the battery pack, they need long time to become operational and the car can’t be used when the battery is being recharged. Electric motors enable the vehicle to be 100% emission-free, thus greatly helping in keeping the environment greener. Perhaps the biggest advantage of using these motors is the reduced level of pollutants spewed in to the environment. We’ll discuss about each of them, but before that, here’re two major things to keep in mind about electric car motors, in general. Mainly, 2 types of motors are used in electric cars: DC motor and AC motor. The performance of an electric car heavily depends on its motors and battery pack. Electric vehicles use a different automotive technology compared to the ones used by conventional vehicles. Electric vehicles are steadily becoming popular all across the world as a good alternative to traditional gasoline-powered vehicles.
