Changes happen in different industries with the booming transition towards green energy. Specifically, in the automotive industry, we can see more and more electric vehicles rolling on the road. Among all the EV components, different types of electric motors play an important role in making the vehicle run. In this article, we will cover four common types of electric automobile motors, explaining their respective features and highlights.

Permanent Magnet Synchronous Motor (PMSM)

The permanent magnet synchronous motor (PMSM) is a type of AC motor that utilizes permanent magnets in the rotor to create a magnetic field. The stator, which is the stationary part of the motor, contains windings that are energized to produce a rotating magnetic field. These two magnetic fields interact with each other to produce movement. Typically, PMSMs are efficient and offer high torque density. They have a higher power-to-weight ratio and can operate at high speeds.

Induction Motor (Asynchronous Motor)

The induction motor, also known as the asynchronous motor, is another type of electric car motor. They depend on the electromagnetic induction principle to fulfill their job. Specifically, the stator windings create a magnetic field when being energized, which helps induce a current in the rotor part. This current, in turn, creates a magnetic field that reacts with the stator's field to produce torque.

Generally, induction motors are simpler and robust, making them reliable and easy to maintain. In addition, they can have a lower cost than PMSMs but lack advantages in efficiency, size, and weight.

Switched Reluctance Motor (SRM)

As the name suggests, switched reluctance motors operate on the principle of magnetic reluctance and are controlled by electronic switches. They contain fewer components, as they don't have windings or permanent magnets in their rotor parts. It means that they are cheaper to manufacture and easy to maintain. Additionally, they allow for high-efficiency operation and reliable performance. However, they also have some limitations, like higher noise levels due to the torque ripple.

Brushless DC Motor (BLDC)

The final type of electric motor we will cover is the brushless DC motor. As one of the popular electric car motor types, they offer high efficiency, precise control, low maintenance, and a long lifespan. These motors have a permanent magnet rotor and windings on the stator but do not have brushes like any other traditional DC motors. Instead, they are electronically commutated, typically using sensors to facilitate smooth rotation. The absence of brushes and a commutator also implies quiet operation and less wear and tear during long-term use.
