Description

The SEP mini-turbine can be used to introduce
basic principles of a wind turbine. It consists of
a small electric motor attached to a propeller
and connected to a pair of terminal posts. To
demonstrate how the turbine can generate an
electrical current, it can be connected to an LED
or electric motor. To measure the output, it can be
connected to a voltmeter or digital multimeter –
the faster the turbine turns, the higher the voltage
reading. The mini-turbine can be used to carry out
simple investigations into the effects of different
wind speeds and angles on output, using a desk
fan, for example. The wind speed can be varied
by using the settings on the fan. The mini-turbine
can be held in the hand or, for a more quantitative
approach, held in a clamp stand, which allows
distances and angles to be measured more
accurately.
