2.5 HP Continuous Duty Motor
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. Our motors are built
for endurance and reliability and are backed with an industry
leading 10 year warranty.
Pulse
Width Modulation (PWM Circuit Board)
PWM is
a new electronics technology that will soon be found on most
premium treadmills. PWM control boards came out in treadmill
applications in the mid-90's. This new technology provides the
following advantages:
SILENT
Because
the DC voltage is much more "pure," PWM circuit boards do
not require a choke and capacitor to filter out electrical
"hum." With the electrical "hum" practically eliminated, the
treadmill is dramatically more quiet than a treadmill with
a SCR board. PURE VOLTAGE, MORE POWER
Both
PWM and SCR control boards take AC power (alternating current)
and "rectify" it into DC (direct current) voltage. AC voltage
is a constant change of positive/negative current 60 times
a second. That's where we get the term "60 cycle." In other
words, the current is "chopped" 60 times per second. PWM (Pulse
Width Modulation) boards will "chop" it 1200 times per second,
or 20 times faster with pure DC voltage. Because of the "pure"
DC voltage, the motor is "seeing" stronger current. The result
is higher "pure" voltage with less amp draw.
LOW AMP
DRAW
PWM allows
much more tolerance to heavy weight users due to a lower amp
draw. Amp draw is what throws a breaker in your home when
too much energy is demanded.
LOWER
COST
PWM circuit
boards are expensive to produce. But the real savings comes
from NOT purchasing a choke and capacitor, as well as a larger
flywheel.
SMALLER
FLYWHEEL
Since
the motor is receiving and outputting more pure energy, it
does not have to rely on a large flywheel to keep the treadbelt
moving. Smaller flywheels can be utilized.
Frame
Smooth
Fitness Uni-Weld frame is used by many of the top treadmill
manufacturers, including Life Fitness, Precor, and Trotter,
and of course, Smooth FITNESS.
WELDED
vs. BOLTED FRAMES
In a
bolted frame, the size/diameter of the holes that need to
be drilled on the frame are always larger than the diameter
of the bolt. This leaves room for movement, especially over
a long period of treadmill usage, and leads to frame fatigue
and failure.
STEEL
vs. ALUMINUM FRAMES
Steel
is a typically less expensive than the extruded aluminum used
in some competitor frames. Aluminum is more expensive, and
costs more to weld. It is very rare for either a steel or
aluminum frame to fail, and most manufacturer's have never
replaced a frame under warranty.
Elevation
Elevation
mechanisms come in many different forms. The most effective
and durable elevation assemblies are worm-gear driven electronic
elevation motors.
Worm-gear
electronic elevation systems use a separate, powerful motor
to elevate the treadmill while in use. Typical elevation motors
will have a thrust value from 400 to 1000 pounds, therefore
lifting the deck without any hesitation while exercising.
Rollers
2"
diameter rollers with a rust resistant steel finish and high
quality bearings press sealed into each end. Hardened,1.9 Carbon
steel wall construction. The longer length on the tube places
LESS stress on the bearing, extending the life. Only the Smooth
5.15 treadmills have rubber sleeves on both the front and rear
roller, which allow for less tightening of the treadbelt, and
thus much longer wear on the belt, deck and roller bearing.
Belt
2-Ply,
100% Polyester low friction sole backing with Black PVC non-slip
beam top. Black PVC (poly vinyl chloride) is the industry standard
for all treadmill belts. High wear and tensile strength help
keep this belt a top performer for several years. The 100% Polyester
backing is "whisper weaved" for very low friction, and thus
a very quiet belt in use.
The 20-degree
seamless diagonally fused belt is incorporated to help reduce
noise. A belt with a perpendicular or straight across splice
causes excessive noise when the belt crosses over the rollers
on each end, creating a "thumping" noise.
This is
the highest quality 2 ply belt in the industry. Manufactured
in Spain, our high standards have been incorporated into this
high quality tread belt.
The belt
is pre-lubricated with silicon and will not need additional
lubricating at delivery.
Deck
Thick high-compression
pressboard made out of particulate and fibered wood. The laminate
black top, also known as a phenolic deck coating, is a micro-screen,
lubricate trapping laminate. Phenolic decks have a micro-screen
that acts as a net for the silicon lubricant, thus making the
silicon "catch" within the "micro-valleys" that are created
by the micro-screen.
CLEANING
- Cleaning the top layer can be done by using a light cleaner,
such as glass cleaner. DO NOT USE any chloride based cleaners
such as bleach. CLEANING the underside of the belt should be
done by loosening the rear roller and wiping the deck and the
back of the belt (the polyester side) with a clean towel ONLY,
WITH NO CLEANERS. After cleaning, re-apply new silicon to the
deck and adjust.
Optical
Speed Sensor
An Optical
Speed Sensor is used in combination with the PWM motor controller
to produce the smoothest speed changes. The optical eye actually
counts the revolutions of the motor directly at the axle. The
PWM motor controller then averages the input count from the
optical eye to produce a consistent speed regardless of load.
