4. Experiment procedure
In order to conduct the experiment, the following
apparatus is additionally required:
1 Experiment motor with
transmission U10375
1 DC power supply 0–20 V (230 V)
U33020-230
or
1 DC power supply 0–20 V (115 V)
U33020-115
1 Stand base:
U13271
Experiment leads
•
Set up the experiment motor on a stand base.
•
Insert the axle of the Watt governor deep into
the chuck of the experiment motor and clamp
it tight.
•
Connect the experiment motor to a power
supply.
•
Initially set the output voltage to 0 and then
turn on the power.
•
To increase the speed, gradually increase the
output voltage and observe how Watt’s gov-
erner changes its angle.
