Is it a problem if the magnets in an electric vehicle's motor are broken?

1. The magnets in an electric vehicle's DC motor are mounted on the motor's outer rotor and are the primary source of power for the motor (which, along with the drive coils, forms the motor).

2. There are two ways in which magnets in an electric vehicle's DC motor can be damaged: weakened magnetism or magnet detachment. Weakened magnetism reduces the motor's output power (making it weak), while detached magnets can become lodged between the stator and rotor, damaging the motor.
