Polarity of a Battery Powered Motor
Polarity of a Battery Powered Motor
Problem:
Will changing the polarity of a battery powered motor change the direction the motor spins?
Hypothesis:
If the polarity is changed on a battery motor, I think it will change the direction the motor spins. I think it will act like reverse button.
Methods:
I. Connect a battery powered motor to a battery using a simple circuit
a. Check that the negative of the battery is connected to the negative of the motor
b. Check the direction the motor is spinning
II. Turn the motor around and connect it to the simple circuit again
a. Check that the negative of the battery is connected to the positive of the motor
b. Check the direction the motor is spinning
Materials:
1. 3 AA Batteries
2. Simple Series Circuit
3. Motor
Information Gathered:
I found that when the negative of the battery is connected to the negative of the motor, the motor spins in a clockwise direction. When I change the polarity and connect the battery negative to the positive on the motor it spins in the opposite direction.
Conclusion:
My hypothesis that a motor would spin backwards if you reverse its polarity was right. I tested the direction a motor spins with forward and reverse polarity by turning the motor around. The motor spins clockwise normally, and spins the opposite way when turned around.
