All these companies are trying to you know bring down when you get peak torque available in the engine range for internal combustion engines because they know that's a more responsive, more fun to drive vehicle and Electric cars actually do this the best because they have that peak torque available from zero RPM, So in City environments You know where you're maintaining these low speeds. They're actually a ton of fun because you always have that peak torque available So, how are they able to do this?

Well, basically we're going to talk about motors generators and then get into why that peak torque is available at zero RPM So if you haven't already I have a bunch of different articles on how electric motors work This is going to be a very generic overview So if you want more details check out the links in the article descriptions. I have quite a few articles on this subject

But very basically how a motor works is you supply a current through a wire Which is going to be your motor ultimately you have a magnetic field, so you've got North-to-south Magnetic field traveling right here and so as that current travels through that wire Within that Magnetic field it's going to generate a force to rotate that that wire there so basically rotate the motor the armature of the motor is going to start to Spin and This is covered by fleming's left hand rule now old convention states that current travels from positive to negative Electrons are actually traveling in the opposite Direction.

But that's the convention so using fleming's left hand rule if you line up the field with your pointer finger your force or your current rather with your middle finger then your thumb is going to point the direction of the force and so as you can see there Field current Force so it's going to Force that to rotate So the more current you applied to this copper wire the more it's going to want to Spin and will Spin faster and faster Now a generator is basically doing this in reverse and so as a result the current is going to be in the opposite Direction.

But basically you're going to be rotating the armature so spinning that copper wire Through that magnetic field and so to use fleming's right hand rule because this is in reverse so if you have the field coming from your pointer finger you've got.
