Week 6 Lab Assignment: Electric Motors

Recommended Materials
1. Lab Sheet
2. Pencil and paper
3. HVAC Textbook
4. Internet Search

Scope

This lab will help the student to learn how to recognize motors and their purposes used in the HVAC/R field.

Procedures

1. Use a textbook and the internet to search for electrical Split Phase Motor use in the HVAC/R field.
2. The Motors you need to locate and list out their components:
  1. Resistive start, Inductive Run Motors
  2. Shaded Pole Motors
  3. Permanent Split Capacitor Motor (PSC)
  4. Have your instructor to give you these three different types of motor.
  5. Your instructor will demonstrate to you how to disassemble these motor.
  6. List all the data from the name plate.
  7. Take one motor at a time apart and inspect the internal parts and record the names of these components.
  8. Reassemble the motor and have the instructor inspect your job.
  9. Wire the motors one at a time to a power source; have your instructor inspect the wiring.
  10. Start the motor and record the amperage, and voltage.

Research Questions

1. What are the differences in these motors?
2. Which one of these motors are the least efficient?
3. From the data plate, what is the definition of each of these terms?
4. What is the purpose of the stator?
5. What is the purpose of the shaded poles on a Shaded Pole motor?
6. What is the purpose of the capacitor on a PSC motor?
7. What was the operational voltage and amperage?
