Please do not take this as a put-down.

Just a correction.

I am the kind of guy that emails the Science Channel one a week because
they use incorrect terms. (Such as saying 10,000 Volts of power, or 100
Amps of power)

The torque on an electric motor is (roughly) constant as a function of
speed. The Power (HP) falls off with speed.

Work is force times distance. Torque is force. In a rotating system
distance is related RPM so Torque times RPM is related to HP

I thought horsepower was how fast you hit the wall and torque was how far you moved the wall? ;)
