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.
UNIQUE
LOWER CIRCUIT BOARD
Smooth
Fitness has designed a unique lower circuit board for
the Smooth 7.1 that is much smaller and more reliable
than any other on the market today. All circuits and diodes
are enclosed in a steel casing preventing dust and dirt
as well as heat from causing a failure.
Elevation
Elevation
mechanisms come in many different forms. The most effective
and durable elevation assemblies are worm-gear actuator
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 pushing up the deck without any hesitation while
exercising.
Most
manufacturers mount their actuators backwards, in essence
pushing up the deck, which is exactly the opposite of what
an actuator is designed to do. Our Smooth 9.15 treadmill
features a patented actuator elevation system, which pulls
the treadmill up. Therefore, our machines have approximately
2000 lbs. of pulling capacity, which is why they operate
so quietly. They will last forever!
Rollers
2.5"
diameter rollers with a rust resistant steel finish and
high quality Japanese 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 9.15 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.
Smooth
9.15 treadbelts are unique in that we use a proprietary,
non-slip tread pattern, which does not TRAP dirt into the
square grooves that an ordinary treadbelt would have. Easy
to clean and more durable, our treadbelts have a higher
quality look and feel.
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. The belt
is pre-lubricated with silicon and will not need additional
lubricating at delivery.
Deck
1"
Thick, high-compression pressboard made out of particulate
and fibered Douglas Fir 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. Our decks are reversible
and laminated with wax on both ends.
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
deck lubricant 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.
You
won't find a comparable treadmill at this price.
