How does Electric Motor Work?
An electric car motor uses a current to create a magnetic field at the fixed part of the machine, called the stator, whose displacement sets in motion of a rotating part (called the “rotor”).

Understanding how an electric motor work is pretty simple. Here’s a simplified explanation of how a car's fourpole threephase AC induction motor works.

It starts with the battery in the car that is connected to the motor. Electrical energy is supplied to the stator by the car’s battery. The coils within the stator (made from the conducting wire) are arranged on opposite sides of the stator core and act as magnets.

Therefore, when the electrical energy from the car battery is supplied to the motor, the coils create rotating magnetic fields that pull the conducting rods on the outside of the rotor behind it. The spinning rotor creates the mechanical energy needed to turn the car gears, which, in turn, rotates the tires.

Various types of Electric Motors are
1. Brushed DC Motor
2. Brushless DC Motor
3. Permanent Magnet Synchronous Motor
4. Induction Motors
5. Switched Reluctance Motors
6. Synchronous Reluctance Motor
7. Axial Flux Ironless Permanent Magnet Motor

Electric cars are available in different drivetrain options. The placement of the electric motor plays a very important role in the power delivery and purpose of the vehicle.

EVs can come in different configurations, such as a single motor, dual motor, three motor, or a separate motor for each wheel.

Types of Powertrains in EV:

According to the number of motors used in vehicle and their configuration, existing powertrain EVs can be classified into two types: the centralized single motordriven powertrain and the distributed multimotor driven powertrain.

The centralized motor single motor speeddriven powertrain is the most common structure in modern EVs.

Some EVs focused on the distributed multimotor is driven powertrains. The multimotor driven powertrain is mainly classified into three categories.
1. Dual motor powertrain
2. Triple motor powertrain and
3. Four motor powertrain
