Ferrari and Mercedes use electric motor for headrest-hitting torque

With each press of the accelerator, EV drivers push hundreds — and in some cases thousands — of amps of electric current to copper coils. When these coils are energised, they become electromagnets with attractive and repulsive forces. The magnetic force created by a stationary stator surrounding a rotating rotor produces the torque that turns the wheels of the vehicle.

In July of last year, Mercedes announced it had acquired Yasa for an undisclosed sum and would put its motors in AMG models slated to launch starting in 2025. Yasa’s motors also could completely remove the need for a power train on the so-called skateboard underneath the middle of an EV, Woolmer said. That would open up more space for engineers to package batteries, make more room for bigger front and rear trunk spaces, or allow designers to experiment with new aerodynamic ideas.
