For those of you with electric vehicles, do you notice a vibration when you are moving at low speeds?
Electric motors using permanent magnets are efficient but do not have perfectly smooth torque at low speeds. This variation is called “cogging torque” and it results in a mild vibration that is felt through the car at very slow speeds.
If you have an EV, do you notice this cogging when you’re driving slowly like creeping in traffic or in a parking lot, or moving in and out of your garage? Do you find it objectionable? Did you even notice it?
