A motor can act as a generator.
Connect two motors with one lead. Turn one and the other turns.
Count how many times the second turns when the first is turned 100 times to see how efficient
the motors are.
The energy transfer from one NXT motor to the other was higher than 90 percent yesterday.
Today we are checking out the motors in the WeDo sets.
Connect
Turn
Count
These motors are only about 60 percent efficient at a medium speed.
