Electric Vehicle has many components and one of the most important components is Electric Vehicle Motor.
In this guide, you’ll get to know the complete details about Electric Vehicle Motors.
As mentioned above one of the important pieces of an Electric Vehicle is the Motor.
Let’s first understand how does an Electric Vehicle Motor works.
The battery in the vehicle supplies electrical energy to the stator (fixed part of the Motor) which in turn creates a rotating magnetic field that rotates the Rotor (the rotating part of the Motor). The spinning rotor creates the mechanical energy need to rotate the wheels.
Important components of Electric Motor
As mentioned above the Stator is the fixed part of the Motor. The stator consists of coils made from the conducting wire and is arranged on opposite sides of the stator core. When electrical energy is supplied to the Stator the coils create rotating magnetic fields.
The Stator is the rotating part of the Motor. Because of the rotating magnetic fields generated by the Stator, the Rotor starts to rotate providing mechanical energy to rotate the wheels.
Types of Current used in Motor
Direct current (DC)
Direct current (DC) refers to the electric flow in a single direction. Constant potential difference is used to generate the unidirectional flow of current. Electric Vehicle Batteries functions using direct current.
Alternating current (AC)
An alternating current (AC) is an electric current in which the electrons periodically change direction. Most often AC follows the pattern of a sine wave. The main motor of the electric vehicle which provides traction to the vehicle uses an Alternating current. So, the Direct current (DC) from the Batteries needs to be converted into Alternating current (AC) via an inverter to run the Motor.
Types of Electric Vehicle Motor
In a synchronous motor, the rotor creates a magnetic field, so the rotational speed is directly proportional to the frequency of the current that powers the motor. This is ideal for driving which requires frequent start and stopping at low speeds.
In an asynchronous motor, the stator generates a rotating magnetic field. This motor is mostly used when driving at elevated speeds for long periods of time.
