This is a nitpick for sure, but as I understand it, electric motors provide pretty much constant torque throughout their operating range, which is one of their benefits. It's the speed of the motor that varies, and consequently the power, which is a function of torque times speed.
- ttshaw1 2y agoNo, electric motors exert the most torque at zero RPM. That's where you can put the most current through the coil, because there's no back-EMF. It's why EVs are so zippy from a stop. The torque-speed curve is a straight line, with 0 torque at max RPM and a constant power.
- ttshaw1 2y agoSorry - not constant power, obviously, since at the extremes the power is 0.
- floxy 2y agoFor synchronous motors. Induction motors (like the auxiliary/dual motors used on something like the Chevy Equinox EV) have a different torque/speed characteristic. https://www.engineeringtoolbox.com/electrical-motors-torques-d_651.html https://www.engineeringtoolbox.com/electrical-motors-torques...
