The 100k deal is primarily because the tech isnt as mass produced as is the rest of the auto industry.
Obviously not the biggest brainbuster ever, but just mentioning...

No, they do not all produce max torque at 0 rpm. You have to look at the PDF spec sheets to find break-down torque and locked rotor torque (0 rpm).
Two terms back I did a project with a 220VAC 3 phase motor and the locked rotor torque was only like 80% of the max torque, according to the MFG's spec sheet.
Hell here is the specific spec sheet. Break-down torque = max torque. Locked rotor = 0 rpm

I will note thought that is A/C and not DC.... but you did specify 'electric motors' which is incorrect. We didnt work as much with DC so I dont know for certain. I dont -recall- it being any different.

I stand corrected..
I just remember reading somewhere they made their max torque, as they didn't need to "wind up"...

Yeah that is for sure. I need to read more on DC electric motors that I forgot from class. Depending how you have power to them, they can basically wind to a infinite rpm. Except that cant happen because they will tear themselves apart.
Hence one of the reasons for speed controls.
