If you are serious about purchasing a quality treadmill, and not some toy that will break down in a short period of time, then there are a number of considerations to think about. One of the most important is the quality of the motor.

A treadmill motor is one of the most significant components to consider when buying a treadmill. It is what drives the treadbelt that you walk or run on. Depending on the quality and power, it can make the difference between a smooth running machine and a loud noise-maker that struggle to run. In most cases the larger and heavier the motor the better. But that is not always the case. The quality of the motor can make a big difference, even if it is smaller. In other words not all treadmill motors are equal.

When comparing treadmill motors you want to go by the horsepower of the continuous duty, not peak horsepower. Peak horsepower is the maximum horsepower a treadmill can reach. Continuous-duty horsepower is a measure of sustained power during regular use. The continuous motor power is what is consistently delivered during heavy usage over an extended period of time.

Since peak horsepower is usually significantly higher than a motor's continuous capability, continuous horsepower better helps you determine which treadmill will accommodate your intended exercise use. Generally speaking, the larger the motor the more powerful it can operate at a continuous rate

Continuous duty is the standard in comparing horsepower. Unfortunately there is no official standard rating and often treadmill manufacturers will exaggerate the actual continuous duty horsepower. Regardless, the continuous duty horsepower rating will give you some guideline, but it is not an absolute.

An indication of the quality of the motor will often be reflected by the extent of the warranty. A 90 day warranty will suggest lack of quality. A warranty of 5 years or more tells you that the motor is built to last, or otherwise the company would go broke having to replace them. In fact, there are a number of treadmill manufacturers that offer lifetime warranties on the motor.
