The Porsche Taycan is a remarkable feat of engineering, combining the performance and luxury of a sports car with the efficiency and sustainability of an electric vehicle. In this blog post, we will take a closer look at one of the key components that make the Taycan so special: its electric motors.
The Taycan is equipped with two electric motors, one on each axle, that deliver a total output of up to 761 horsepower and 774 pound-feet of torque. These motors are not ordinary electric motors, but permanent magnet synchronous motors (PMSM), which offer several advantages over other types of electric motors.
PMSM are more compact and lighter than induction motors, which means they can fit better in the limited space of a sports car. They also have higher power density and efficiency, which translates into more performance and range. PMSM are also more responsive and smoother than induction motors, which enhances the driving experience and comfort.
One of the challenges of using PMSM in an electric vehicle is that they generate a lot of heat, which can reduce their efficiency and lifespan. To overcome this challenge, Porsche has developed an innovative cooling system that uses a special coolant fluid to circulate around the motors and remove excess heat. This system also cools the batteries and the power electronics, ensuring optimal performance and reliability.
Another challenge of using PMSM in an electric vehicle is that they require a complex control system to regulate the power delivery and the torque vectoring. To achieve this, Porsche has developed a sophisticated software that monitors and adjusts the parameters of the motors in real time, depending on the driving mode, the road conditions, and the driver's inputs. This software also enables the Taycan to have a two-speed transmission on the rear axle, which improves acceleration and efficiency.
The electric motors of the Porsche Taycan are a testament to Porsche's engineering excellence and innovation. They are one of the reasons why the Taycan is not just an electric car, but a true Porsche.
