Electrical Machinery Laboratory ELEN 344

Location: James Moore Hall Room 134

Purpose of the Lab: This laboratory is used reinforce concepts in transformer and rotating machinery including both D.C. and A.C. machinery. This set of laboratory experiments covers related topics in Electrical Machinery I (ELEN 342). These experiments covers the fundamentals of single-phase A.C. transformer, three-phase A.C. transformer polyphase A.C. motors and generators and D.C. motors and generators. This laboratory also covers the basics in PLC control of A.C. and D.C. motors and A.C. drive control of motors.

Equipment/Apparatus: The following experimental equipment are available for laboratory use.

· Hampden 2-hp motor-generator sets

· A.C. voltmeter

· D.C. voltmeter

· Agilent 34401A 6 1/2 multimeters

· Dell optiplex GX270 computers

· Lab-Volt 3210 PLC (2)

· Lab-Volt: Squirrel-cage A.C. motors

· Synchronous machines

· Single phase transformers

· Three-phase transformers

· Transmission line-models

· PLC software from Rockwell for SLC 500

· Lab-Volt fractional hp control sets for motor-generator sets

Experiments:

Experiment 1	Determining the parameters of the model for a single-phase transformers
Experiment 2	Auto-transformer measurements
Experiment 3	Three-phase transformer measurements
Experiment 4	Introduction to Relay ladder logic and conversion to PLC control and measurement of an A.C. squirrel cage motor
Experiment 5	Squirrel-cage motor measurements and modeling (manual and A.C. drive control)
Experiment 6	PLC control of D.C. motor (time delayed start)

Faculty: Dr. Charles A. Singleton
