What you need to know about an electric car engine

No more emissions, pollution and combustion, the electric car seems like a solution to a greener, more profitable and more peaceful future. The electric vehicle, which has been successfully adopted since the 2000s, is popular for its advanced technology and minimal environmental impact. Today it is no longer surprising to meet, for example, the Renault Zoe.

accelerator pedal, which only needs to be pressed for the battery to generate


Current.

what developments?

DC motors

Historically,


The DC electric motor was the first successfully used electric motor.


even more so with a Citroën AX or a Peugeot 106 in the 90s.

Also called direct current, the DC motor is used in radio-controlled toys, among others, and has a stator, rotor, brush, and collector. Thanks to direct power from DC from the on-board batteries, it is technically quite simple to adjust the rotational speed, so this choice of engine quickly became the standard for the first generation of electric vehicles.

However, due to the delicate maintenance at the collector level, a fragile and expensive part, brushes that need to be changed regularly, and a maximum efficiency of 90%, this model is a little outdated for use in an electric vehicle. This type of engine was phased out due to lack of performance, but, for example, is still available in RS Components.   

Asynchronous motors

Most


an asynchronous motor is commonly used today, we find it


at Tesla Motors. This engine is compact, robust and reliable, but we are not


found that one stator rotor winding directly affects its


profitability from 75 to 80%.

Synchronous motors

The most promising is the synchronous motor, which provides zero slip, better power density and higher efficiency. This synchronous motor with magnets, for example, does not need rotor windings, so it is lighter and lossless. The PSA group and Toyota are moving towards this technology.

Born over a century ago, the electric car is gradually taking revenge on the traditional car. Thanks to technological progress, the electric motor is constantly evolving and losing weight, size and fragility. The electric car is now taking its place in the world of tomorrow, but in combination with other solutions such as cycling, public transport, etc.
