Reflections on the electric motors of the future

The design, location and integration of electric motors in vehicles is rapidly changing to achieve maximum efficiency without losing power and occupying as little space as possible.

Around 200 companies are engaged in the manufacture of traction motors for electric vehicles. By 2025 the electric vehicle business could move about $ 500 billion, of which $ 25 billion would be motoring. While battery technology seems to be lithium-depleted also for future motors you can check on this website https://minhmotor.com/danh-muc/dong-co-dien-motor/, with some variations in the rest of the chemical components, the industry of electric traction motors is much more complex.

In some cases it is the engine manufacturers who perform the integration in the chassis, the adjustment with the rest of the components of the vehicle and the electronic suitability. In others, the manufacturers themselves carry out this operation. This feature opens up a range of possibilities that can significantly affect the final price of the traction system. Another completely different case is the specific motors for motorcycles and electric bicycles. The price of these vehicles has an important impact on their engines and components such as neodymium and rare earths.

Most pure electric vehicles still place the engine in the front bonnet, although the trend begins to change by bringing them closer to the wheels, so it is not uncommon to find motors on the axles and even on the wheels, releasing much space in the Interior of the vehicle while lowering the center of gravity and increasing power and torque. In the case of in-wheel motors, the disadvantage may be in the instabilities that can be caused by non-suspended masses whose movements are not damped by the suspension.

It is also common to find electric motors integrated in the transmission, especially in the case of hybrids where they are more efficient to obtain increase the energy when working together with the combustion engine. In some cases the electric motor is located near the combustion engine or the exhaust pipe so it is necessary to tolerate very high temperatures.

The requirements that these engines must meet are above all high energy efficiency and profitability. They require peak powers that sometimes reach twice the nominal and a very high torque that is maintained throughout the power range.
