Vertical Resistance:

The Experience Line AMTs use a three phase AC generator, and all current being drawn
throughout the unit comes from this generator. The only other power supply in the unit is a variable
power supply, used to provide variable control of mechanical resistance, in this case (Magnetic
Force). The user selects the desired level of resistance at the console, and the console passes that
request along to the lower control module via the serial communication through the data cable. The
processor on the lower control module then adjusts the output of the variable supply to an
appropriate value to facilitate the user's requested resistance level. That voltage is applied to an
eddy current magnet pointed at the flywheel of the generator, which then determines the amount
of braking force that is placed on the generator. The more voltage sent to the eddy current magnet
