Rotor Influence Check Test Procedures
NOTE: Do not run the normal RLC resistance test prior to running a RIC test because the currents involved in
the resistance test may impair the measurement results.
Angle step sizes and other parameters are defined in the system settings. Refer to the “Using system
settings” section in chapter 5.
1.
Connect the low-voltage RLC test leads to the motor leads.
2.
Attach the RIC test template to the motor as described in the “Setting up Fixtures, Test
Accessories, and Lead Connections” chapter.
3.
Check the
Status Bar
to ensure the
Active Folder
and
Active Record
fields display the
intended target destinations for your test data.

4.
Select the
RLC
mode icon in the
Mode Menu
then the
RIC Mode
icon in the
Mode
Submenu
. The starting screen should then look like the one shown above.
5.
Starting at 0 degrees, push the
Start (PTT)
button to execute the first set of tests on
that position of the rotor. The Baker DX will automatically run three inductance tests—
one for each lead. The results of these tests are presented in the
Display Area
.
6.
Move the rotor to the next shaft angle and press the
PTT
button again. As above, three
inductance tests will be performed and the results plotted on the screen.
7.
Continue moving the shaft and running tests until the required number of angles have
been tested. (2-pole motors require 360° of shaft rotation to get a usable X-Y plot. 4-
pole motors require 180°, 6-pole motors require 120°, 8-pole motors require 90°, and so
on.)
