How much torque though? HP is nice but power is in the torque as much if not more than the voltage(HP)

[–] Zink@programming.dev 3 points 2 weeks ago (2 children)

The voltage/hp comparison there doesn't really fit.

Power is in watts or horsepower. You multiply the torque with the RPM and a scaling factor to get power.

A higher voltage system could probably be expected to produce more torque and power from the same size motor, but a lot depends on the design of the motor.

Then to answer "how much torque though," I haven't looked into it but electric motors have a very nice torque curve across the RPM range. If a motor made all that power with low torque, then it must spin at super high RPM and need to be geared down.

Car engines, for probably the past 100 years, have always been advertised based on their peak power rating, not what they can produce continuously. Cars are not designed to have their accelerator pedals floored for hours on end, nor is this even possible to do, as you'd eventually hit a curve and need to slow down.

This is especially the case for high performance vehicles, which usually have more demanding maintenance requirements just from normal operation, let alone from being abused like that.
