Operating the Motor with AC Power: Part I

The linear motor uses alternating current. Each time the current reverses, the magnet in the motor travels in the opposite direction.

Step 1

For this lab you will need to use the AC power source (pole reverser) and the linear motor.

Step 2

00

First, to ensure that the AC power source is working properly, you will need to hook it up to a current meter.

Step 3

01

Connect the banana cables to the analog curretn meter and AC power source.

02

Now turn the AC power source one full rotation. The current meter should detect a positive and negative current depending on the orientation of the battery. What do you notice as you turn the battery? Is your power source working as you expect?

Step 4

03

Now, gather your linear motor. You will use the AC power source to drive the motor.

Step 5

05

Connect the banana cables to the AC power source and the motor.

04

Crank the power source one full rotation. What happens to the motor? Is this what you expected? Experiment further with the power source and linear motor.
