7 Lab 3 phase Motor Control
BRAE 216
Fall 2011
Date Performed 11/3/11
Lab 7
3-phase Motor Control Circuit
Objectives:
Learn basic wiring principles
Equipment:
Motor starter
Hp 3-phase induction motor
Pushbutton controls
SJ wire
Plugs
Procedures and Methods:
1. Construct the 3-wire control circuit on the board, using the materials
provided. The SJ cord is used to connect the motor to the starter and the
plug to the starter. The 14 AWG is used everywhere else. Wire the 3phase motor to the low voltage option.
2. For wiring diagram, see attached pages.
Discussion:
Figure 1 Cutaway of a 3-phase induction motor
In lab, this we assembled the circuits between a motor, a motor starter
and a switch. Our group found it fairly easy to follow the diagram on the board
and wire the correct wire in the correct spot. The most difficult part of this lab
was connecting the SJ wire to the motor and matching up the wires. It was
highly beneficial to see and assemble the materials that we have been talking
about in class. In addition, this real world application will help us in the future.
Overall, this lab was very helpful to our understanding of how a motor works and
how to wire all of the components together correctly.
