When looking at treadmill specs, it can be confusing when it comes to the motor. Words like “peak” and “duty” are thrown around, along with the acronyms CHP and HP. Let’s dispel the confusion so you can know a quality treadmill when you see one.
Difference Between “Peak” and “Duty” Treadmills
First thing to clarify is that neither of these terms indicate the actual strength of a treadmill motor. Instead, they break down to mean this:
- Peak Treadmill Duty – The measurement of the highest speed at which a motor will perform, but only for a short period of time. This number is reached by having the motor run with a minimal load.
- Duty Treadmill – This measurement reaches for a bit more accuracy by looking at averages: averaging the runner, runner’s speed, and how long the treadmill will be in use.
The Difference Between ‘Continuous Duty Horsepower (CHP)’ And ‘Horsepower (HP)’
Next thing to understand is that a continuous duty horsepower (CHP) motor will be stronger than a horsepower (HP) motor with the exact same number. How is this possible? Because of how the two terms are defined:
- Horsepower (HP) – This measurement is much like the peak treadmill duty. It measures the maximum performance of the motor, though, usually with a minimal load or zero weight on the belt.
If you’ve ever wondered why there can be such a large differential in price when it comes to treadmills, part of that comes down to the motor. A motor in a cheaper model will usually be rated by HP, and tends to use the word “peak” along with the motor description.
- Continuous Duty Horsepower (CHP) – The CHP is found by measuring the continual use of the motor at the highest listed horsepower. This is considered the most accurate measurement and most helpful to runners who plan on doing a good bit of training on their treadmills.
All of NordicTrack’s current treadmill motors are rated CHP because we know you are looking to make a smart investment in your health. For example, our Commercial 1750 treadmill has a 3.8 CHP DurX™ Commercial Plus motor, which could also be listed at 4.5 HP if we wanted to artificially inflate our numbers. But we know our customers are looking for endurance from our machines, so you will always get the CHP as our motor rating.
