The key design factor in a VAV system is the control of. the supplied air. The terminal unit should be sized to. take advantage of as much of its potential capacity as. possible. Without this fundamental consideration, the. customer has not received the best value for their VAV. system design.
The amperage rating on the DC motor is not the amperage the treadmill will be using from your wall outlet. Most treadmills only need 10-12 amps from the wall (or less), so a 15 amp circuit is fine, regardless of the rating on the motor. Just look at the amperage rating on the treadmill to see what your wall outlet needs to supply. #2 see #1. #3 Current is always lost in the form of heat when used to power a device. Be it in the motor, the electronics or even the line supplying the current.
Usage. The more you use your treadmill, the more energy it uses. However, how you use the treadmill also determines the amount of energy consumption. A 3.0 horsepower treadmill motor doesn't always run at 3.0 horsepower.If you are walking at a leisurely pace with no incline, it might only use 1-1/2 horsepower to power the machine, consuming only half the energy during that time.aluculations. You can calculate the amount of energy your treadmill consumes and how much it costs to run it. Because you can't realistically figure how often you are using the treadmill at full capacity, these calculations are based on the full wattage rating.
