Kinetic Art & Technology Corporation's SEMA Technology has many applications in green technology.
SEMA's industry leading efficiency makes it a natural choice for wind turbine generators. The fact
that SEMA generators tend to be efficient over a broad range of speed and load makes them
especially efficient for wind turbines that operate at variable speeds. The fact that they
do not have cogging torque also allows wind turbines to spin in very low wind when conventional
permanent magnet generators may stall. The high peak power capability of SEMA is extremely useful
for handling surge loads as well.
SEMA's industry leading efficiency makes it a natural choice for electric vehicles.
The full power and efficiency of SEMA technology is available operating as a motor
or as a generator. This is highly desirable for hybrid electric vehicles and full
electric vehicles employing regenerative braking. SEMA machines tend to be efficient
over a broad range of speed and power, which is especially advantageous in most
electric vehicle applications. Also, the incredible peak
power of SEMA allows for extra torque when needed, such as when a vehicle begins
accelerating or when aggressive regenerative braking is needed. The fact that KAT
engineers have found ways to employ the advantages of SEMA into various package
options allows SEMA to be incorporated in a vehicle in many different ways.
Fuel Cell Vehicles
The power produced by a fuel cell is electric. Therefore, a SEMA motor has many
of the advantage described above for electric vehicles. Unlike pure electric vehicles,
fuel cell vehicles require a high power compressor to operate. SEMA's
efficiency is of great advantage for such an application. In fact, KAT has demonstrated
a motor specifically designed for fuel cell vehicle compressors.
One might not immediately think of SEMA technology when thinking of solar power.
However, there are two places where SEMA technology has clear advantages.
Some solar power applications incorporate devices such as Stirling engines,
which convert the sun's heat into rotary motion. This in turn drives
a rotary generator. The high efficiency of SEMA machines makes them a
natural choice as the generator for these applications.
The high peak power capability of SEMA is
extremely useful for handling transient loads as well.
Many solar power applications also employ sun tracking devices. SEMA technology
was originally developed for servo positioning applications.
The lack of cogging torque and the very limited
torque ripple makes them very accurate. SEMA's high efficiency at various operating
conditions, as well as its peak torque capability, also make it an excellent
choice for sun-tracking solar power applications.
SEMA technology scales completely from generators for large hydroelectric power plants to the
small backyard generators.
SEMA's industry leading efficiency makes it a natural choice for generator applications.
The fact that SEMA generators tend to be efficient over a broad range of speed and load,
plus the fact that they do not have cogging torque, makes them especially useful for recovering
energy at variable and low speeds, as well as variable load conditions.
The high peak power capability of SEMA is extremely useful for handling peak loads.
Green Technology Generators
Whether it is a biodiesel genset powered by a renewable fuel, or an even more innovative
power source, whenever a generator is needed, SEMA's industry leading efficiency makes
it a natural choice. An important part of any green technology is efficiency, as well
as the environmental footprint of the system. SEMA delivers. The high peak power capability
of SEMA is extremely useful for handling peak loads as well.
High Efficiency Motors
Conservation is an important element of green technology. The industry leading
efficiency of SEMA motors can be employed in most applications where electric
motors are used today. As electric motors consume a substantial amount of
the total electric energy produced in the world, transitioning to highly
efficient SEMA motors can save a substantial amount of energy worldwide.
