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.
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 7.1 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 7.1 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
7.1 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.
