Chapter 16 QUIZ

A-C MOTORS

1. What is the name of the only d-c motor which will run on a.c.?
2. What is the polarity of the secondary if the primary is north?
3. Do a-c coils have a fixed polarity?
4. What does "Polyphase" mean?
5. What are the units for measuring phase?
6. What is the meaning of "out-of-phase?"
7. Does any mechanical part of a stator move?
8. What does move in a rotating magnetic field?
9. Does the squirrel cage rotor have any electrical connection to a source of supply?
10. How does current get in the squirrel cage rotor?
11. The squirrel cage rotor is what kind of a circuit?
12. Does a wound rotor have an electrical connection to a source of supply?

13. How does current get in the wound rotor?
14. How is a synchronous rotor energized?
15. What is "magnetic lock?"
16. Name the three types of single phase motors.
17. What two methods are used to split single phase into two phases?

A-C MOTORS

1. The series-universal motor.
2. South.
3. No. A.C. coils reverse polarity with every re verse of current.
4. More than one time.
5. In electrical degrees.
6. Out-of-time.
7. No.
8. Only the flux field produced by the stator windings.

9. No.
10. A voltage is induced in the squirrel cage rotor. This voltage forces current through
the windings. Always a shirt circuit.

12. No.
13. By induction-exactly like the squirrel cage.

14. With d.c. from an exciter, fed to the rotor via slip rings.
15. The field between rotor and stator poles of a synchronous motor.
16. Series-universal, repulsion-induction, and split phase.

17. resistance and a condenser.
