No, 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...
