An Investigation of PV Powered Brushless DC Motors for Solar Pumping

An autonomous and elegant integration of electric motor and pump for use with a solar domestic hot water system

• Broschiertes Buch

Produktbeschreibung

Typical solar domestic hot water systems use a liquid
working fluid to transfer heat from the solar
collectors to the hot water storage tank. This book
presents the results of a detailed investigation of a
unique design and integration of electric motor and
pump to circulate the liquid working fluid. The
motor''s energy source is electricity that is
generated from the sun by a photovoltaic module,
creating an autonomous heating system. The design
under review is a brushless DC motor that utilizes
the magnet of a "mag-drive" pump as its rotor. This
motor and pump technology, and integrated design
results in both increased component utilization and
increased reliability. The power switching devices of
the motor perform commutation and maintain the
photovoltaic module at the maximum power point. The
pump magnet acts as the magnetic coupling and the
motor rotor. Increased reliability is achieved
through the use of solid state power electronics for
commutation and the replacement of a dynamic pump
seal with a static O-ring seal. This investigation
reviews each major component''s characteristics under
a variety of conditions to identify appropriate
design choices and areas for improvement.
