I have a 1/2HP electric motor on a power saw, and that motor is fairly large. I just bought a portable pump for transferring water from items such as a flooded washing machine, bathtub with clogged drain, etc. That motor is only about 35% of the size of the motor on my power saw, yet the tag says it's a 1/2HP motor.
How can one 1/2HP motor less than half the size of another 1/2HP motor produce the same horsepower? Is there another factor to take into account besides the HP? Is it torque, or some other factor? Somehow I cant see how this small pump motor could power my saw....
Thanks
