Electric Yacht - the best Choice
Clean, Green, Quiet!
Simple, high quality, well-engineered, and less expensive:
In 2006, engineer Scott McMillian
came up with the idea of electric propulsion for sailboats. Scott, with a few friends and family members, combined
their love of sailing along with their design and engineering skills. Using the engineering philosophy of “keeping
it simple and reliable” they built and tested their initial systems. By 2008 testing ended, and thus began the first
of over 300 Electric Yacht systems. Several
systems were built, further testing Scott’s initial design.
From
testing Electric Yacht learned four important facts: (1) Use the modern, well-proven Permanent Magnet Asynchronous
(PMAC) motor for the best powerful light weight system. (2) Design and build a well-engineered flexible frame
positioning the motor while safely applying shaft thrust and cooling. (3) Build
the most powerful system using low voltage 48v nominal. Finally, produce a marine grade “Plug and
Play” system that can be installed by a good handy Boatwright or boat owner.
In 2010, the second generation of QuietTorque™ motors were
introduced. The QuietTorque™family initially included the single motor QuietTorque™5.0, QuietTorque 10.0, and the
dual motor QuietTorque™ 20.0. All three
of these systems operate at 48v nominal unlike the competition.
By 2015 the QuietTorque™ family
of product has grown to include the 48v QuietTorque™ 25.0, the higher voltage
QuietTorque™ 40.0, QuietTorque™ 45.0 LC, and QuietTorque™ 50.0LC along with the
innovative, no maintenance belt driven saildrive.
To
build quality systems, it takes engineering, testing, and productions skills. Using sophisticated cad design computer
software, the QuietTorque™ systems are robust and simple. Each system design was fully tested before it
became a QuietTorque™ product. In 2013
the original warranty was increased from two years to three years.
By 2014 it had become evident
that a larger facility was needed, one that could handle the growing company expanding
products and sales. In 2015, the assembly, testing, and shipping operations
were moved to Providence, MN.
This
allows us to keep the parts, and fabrication operations to remain with our long
term business partner in Melrose, MN.
The Electric Yacht Extras
Starting
with industrial quality components for reliable power and lower costs, Electric
Yacht adds the Electric Yacht built control module making the motor a uniquely
powerful marine system.
For the best experience, Electric
Yacht builds a marine quality throttle with forward, reverse, and lock in
neutral. The throttle is designed and
built to provide both motor control and the tactile feel to control these
powerful motors. Regeneration is
automatic with the key on while the system in the neutral setting.
The Electric Yacht computer monitor,
coupled with the Electric Yacht control module and Sevcon controller, allow for
set up and reprograming of the motor from the helm. You can modify battery type, battery size,
throttle direction/throw, and regeneration setting (for sailboats). Clearly seen are the state of charge (v),
power draw (amp), regeneration (kW), % of battery charge, hours remaining under
power, motor RPM (before propeller reduction), and motor on/off state. The monitor has a backlight that can be
adjusted for night vision. We have added
audio alarms for change of power (on/off), battery low status, and “other”
alarm state. The QuietTorque™ system can
have multiple monitors for multiple helms.
The frame is the heart of the QuietTorque™
system and allows significant gearing options, making the motor installation
simple. The frame has two thrust bearings built in on each side of the custom shaft
pulley. The high-quality toothed Gates timing
belts efficiently transfer power to the propeller shaft. The motor is normally
mounted aft on the frame high above the electrically isolated shaft. The Sevcon controller is mounted forward on
the frame with the Electric Yacht control module above it. Besides providing a
rigid platform for the motor, the frame provides heat control and increases the
reliability of the system. The Sevcon
controller and Electric Yacht module can be mounted elsewhere in the engine
compartment to reduce the physical size of the motor at the shaft as the
QuietTorque™ low-profile.
The
QuietTorque™ flexible mounting system provides significant ability to orient
the motor in the engine compartment. Note that the Electric yacht motor does not need to be mounted on shock
absorbing “engine mounts”. Combined with
the flexible frame mounting points, the system allows forward and aft, up and down,
and horizontal adjustment. This makes
for simple Plug and Play alignment.
