What are the main types of motors used in new energy vehicles?

New energy vehicles use motors such as DC motors and asynchronous motors. Below are the related introductions about DC motors and asynchronous motors: DC Motor: A DC motor refers to a rotating electrical machine that can convert DC electrical energy into mechanical energy or mechanical energy into DC electrical energy. It is a motor capable of mutual conversion between DC electrical energy and mechanical energy. When operating as a motor, it functions as a DC motor, converting electrical energy into mechanical energy; when operating as a generator, it serves as a DC generator, converting mechanical energy into electrical energy. Asynchronous Motor: An asynchronous motor, also known as an induction motor, is an AC motor that generates electromagnetic torque through the interaction between the air gap rotating magnetic field and the induced current in the rotor winding, thereby achieving the conversion of electromechanical energy into mechanical energy.
I'm quite interested in the electric motors of new energy vehicles. Based on my hands-on experience, there are mainly three types in use today: Permanent magnet synchronous motors boast ultra-high efficiency, reaching over 95%, making them the top choice for most EVs. Brands like Tesla and BYD use them because they offer quick response and energy savings, ideal for daily commutes. Another type is the AC induction motor, which has a simple and durable structure, often used in some SUVs for stable high-speed performance, though slightly less efficient. Then there's the switched reluctance motor, cost-effective for budget vehicles but with more vibration and noise, making it less popular. After recent test drives, I noticed different motors affect acceleration and range. I'd recommend comparing options before buying. Future technologies may trend toward integration and lightweight designs to enhance overall performance.
After driving an electric vehicle for over a year, my experience is that mainstream motors are mostly permanent magnet synchronous type, offering smooth acceleration and quiet operation. BYD's Blade Battery pairs exceptionally well with this drive system. AC asynchronous motors provide more power during climbs or long distances, as seen in my friend's Li ONE which is equipped with one. A reminder to everyone: pay attention to motor temperature during regular charging, as excessive heat can affect lifespan. Simply put, when choosing a car, consider motor efficiency—higher range brings more peace of mind, saving you from constant worries about running out of power midway. During maintenance, gentle acceleration helps protect the drive system. The future trend is towards multi-motor combinations to enhance four-wheel drive capability, which is very practical.
When learning about automotive knowledge, I found that new energy vehicles often use permanent magnet synchronous motors, which are lightweight and efficient; AC asynchronous motors appear in some brands like early Tesla models. Why choose these? They respond quickly, operate quietly, and are environmentally friendly, with the permanent magnet type being especially energy-efficient, making it suitable for urban use. Remember the basic principle: efficient design allows the car to travel farther, and the technology is pretty cool.
