New Energy Electric Vehicles Motor Line

Release time:2022/03/17

There are many benefits of New Energy Electric Vehicles. First, there is no fuel odor as the vehicles operate on batteries, not on gasoline, diesel, or some other type of combustible fuel. Electric vehicles are quiet...the ride is virtually silent. By correctly using regenerative braking, electric vehicles achieve greater brake life as well as create energy through kinetic energy. By using high-tech composite technology, electric vehicles can be much lighter than an ICE counterpart which also helps reduce brake wear along with road wear.

Electric vehicles are much more energy efficient. Electric motors convert virtually all of their fuel energy into usable power. The internal combustion engine (ICE) is less than 20% efficient. Electric vehicles, especially electric buses, provide great public relations benefits. 

Maintenance cost, including fuel cost, is much lower with an electric vehicle. There are no tune ups or oil changes necessary. By eliminating everything on a vehicle maintenance checklist that pertains to the ICE, it becomes a pretty short list. And, by charging at night, the "fuel" for electric vehicles is reduced up to one-fourth the cost of gasoline or diesel.

In an electric drive system, an electric motor converts the stored electrical energy in a battery to mechanical energy. Electric motors consist of a rotor (the moving part of the motor) and a stator (the stationary part of the motor). A permanent magnet motor includes a rotor containing a series of magnets and a current-carrying stator (typically taking the form of an iron ring), separated by an air gap. There are three types of electric motors that can be used in hybrid or plug-in electric vehicle traction drive systems.


Internal permanent magnet (IPM) motors have high power density and maintain high efficiency over a high percentage of their operating range. Almost all hybrid and plug-in electric vehicles use rare earth permanent magnets in their traction motors. Because of the high costs of magnets and rotor fabrication, these motors are relatively expensive. Other challenges to using IPM motors include the limited availability and high cost of rare earth magnetic materials. Despite the challenges, the automotive industry anticipates continuing to use IPM motors in the majority of electric drive vehicles over the next decade.

Induction motors have high starting torque and offer high reliability. However, their power density and overall efficiency are lower than that of IPM motors. They are widely available and common in various industries today, including some production vehicles. Because this motor technology is mature, it is unlikely research could achieve additional improvements in efficiency, cost, weight, and volume for competitive future electric vehicles.


NIDE Group can provide professional new energy motor manufacturing solutions, including new energy motor stator manufacturing line, new energy motor rotor production line, new energy motor assembly line, new energy motor spare parts, etc. Our new energy motor solutions are favored by many well-known new energy electric vehicle manufacturers around the world and have reached long-term cooperation.
