Motor
Output - Continuous duty horsepower ratings are the amount of power a motor
will produce "continuously" at a given RPM (revolutions per minute).
Continuous duty HP is the "working power" of a treadmill motor, providing
constant power to the drive belt. The higher the HP output, the less stress on
the motor resulting in longer life. Both the Trimline T325 and the Smooth 5.15
have adequate horsepower for both walking and running.
Factory

This eliminates the costly overhead from resellers. Trimline sells their T325
treadmill only through retailers.
