Project 33

2 Direction Motor

Build the circuit. Set the switcher (S6) to the

middle position (off), set the meter (M5) to the

1A setting, and place the fan on the motor (M1).

Now set the switcher to the top position; the

motor spins, the lamp (L4) lights, and the meter

measures the current. Set the switcher back to

the middle position to turn off the circuit.

The switcher is used to reverse the

battery connections (from snap A &

D) to snaps B & C, which reverses

the voltage across the motor and

lamp. In the top position, battery “+”

is connected to snap B, and in the

bottom position battery “+” is con-

nected to snap C.

Study the circuit. What will happen to the motor, lamp, and meter if

you change the switcher to the bottom position? (Try it.)

WARNING: Moving parts. Do not

touch the fan during operation.

WARNING:

Do not lean

over the motor.

The switcher’s connections look

like this:
