ELEC 2380 - Electrical - Alternating Current Machines

Credits: 2.00
(2 contact hrs)
(formerly ATEE-2260) ELEC-2380 examines alternators, rotating magnetic fields, A.C. motors, speed control, types of winding, introduction to A.C. motor control. South Campus.

Pre & Co Requisite(s):

Prerequisite: ELEC-2370 or related work experience

OUTCOMES AND OBJECTIVES
Outcome 1:
Upon completion of the course, students will be able to classify alternators by the type of construction used and their principle of operation.

Objectives:

Explain the operation of a filed discharge circuit used with the separately excited field in an alternator.
List the method of cooling and ventilation used in large alternators.
Define synchronous impedance and synchronous reactance.

Outcome 2:
Upon completion of the course, students will be able to describe the construction of the synchronous motor, listing all of its components and explain the function of each component.

Objectives:

Describe the steps in the operation of the synchronous motor from the moment it is energized until the motor locks in at the synchronous speed.
Calculate the synchronous speed of the three-phase synchronous motor.
Explain how a synchronous motor may be used to correct the power factor.
