  • Rigid vac horsepower question

    How does the manufacturer get 6.5 hp out of 120 volts 12 amps for the big shop vacuum?

    Thanks, Roly

    Yes 746 watts=1 electric horsepower
    However there are many other ways to describe/calculate horsepower.

    horsepower VS torque VS RPM

    1000RPM torque 315 you have 5 horsepower

    torque in inch pounds-force=horsepower x 63025 divided by motor rpm

      It's Instantaneous Peak (under one second) Power which is NOT sustainable
