Thank you very much. Exactly what I wanted to know. But, just a doubt, even Induction motors offer full torque at 0 RPM, right? Please correct me if I'm wrong, because that's what a reviewer said while comparing a BMW and the Tesla Model S. Thanks!
Depending on the control system, yes. If you run an induction motor off a fixed-frequency supply, it produces very little torque until it is spinning near it's synchronous speed (typically 3600 RPM, but depends on the supply frequency and pole multiplicity). That's why, for example, bench grinders can take forever to come up to speed.
But modern control systems (which, I might add, are still much simpler than those for switched reluctance motors) can achieve full torque from a standstill (basically by bringing the synchronous speed to near zero).
