Types of motors used in EV

The population is increasing day by day, and as the population is increasing so is pollution. Now, pollution has become a great concern around the globe. This major problem concerning pollution has come up with a revolution of EVs (Electric Vehicle) for a greener globe.

Electric vehicles are a new trend in recent days. As we all know EVs majorly run on batteries, but there is another component that is needed for the EVs to run the electric motor. Fast development in technology has created a space in the market for various electric motors for EVs.

Types of electric motors

1. Brushless DC Motor (BLDC)
2. Permanent Magnet Synchronous Motor (PMSM)
3. Three-Phase AC Induction Motors
4. Switched Reluctance Motors (SRM)

1. Brushless DC Motor ( BLDC)

This motor is similar to DC motors. This motor does not use brushes, and it is an added advantage for the EV as it gives a high power-to-weight ratio and is high in efficiency. These motors can withstand sudden changes in weight and speed. It is most preferred due to its traction characteristics. BLDC motors are fast in controlling speed, torque, and low maintenance. BLDC motors are compact in size. Most Two-wheeler EVs use BLDC motor as it gives high efficiency and low maintenance for the customers.

2. Permanent Magnet Synchronous Motor (PMSM)

A permanent magnet Synchronous Motor is an AC electric motor. It uses permanent magnets embedded in the steel rotor to create a constant magnetic field. In this motor, torque does not change with the load even at low speeds.

3. Three-Phase AC Induction Motors

Three-phase induction motors are widely used as industrial drives because they are economical, reliable, and have long life-span.

4. Switched reluctance Motors (SRM)

Switched reluctance motors are complex in design and a little difficult to control. But it gives a long and constant power range with high power density. These motors are larger and heavier compared to permanent magnet motor and is noisy.
