ENGLISH
If the LED blinks when the rotation speed is sufficiently high, this means that
the maximum value of the variable voltage depends on this rotation
speed.(see section 2.3.2)
2.1.2 Demonstrating the relative movement of magnets and
the coil to produce a voltage
The alternator is turned over, and the
LED is connected to the bushings of
the upper plate.
The coil is rotated relative to the
magnets.
The LED blinks when the rotation
speed is sufficient.
It
can
be
concluded
alternating voltage is generated at the
coil terminals.
2.2
Power level indicator
The power level indicator connected to the alternator coil terminals
demonstrates that the available electrical power* depends on the rotation
speed.
* Note : The electrical power output by the alternator depends on the receiver
connected to its terminals.
2.3
Displaying the voltage generated using an
interface
The coil is connected to an input of the chosen interface (Visio, Primo or VTT
provided with a voltmeter adapter), to display the voltage generated by the
rotating alternator.
2.3.1 Voltage when the alternator is not connected to a LED
The alternator is rotated at no load (without LED), by pushing it with a finger.
