17
(6) Rotor
There are two windings in the rotor. Measure the resistance between #1~#3 and #2~#4
Remove the varnish with sand paper and measure;
Exciter Winding : the resistance among the two points as shown in the photo above by
the low resistance tester. It shall be 8.6Ω.
Field Winding : the resistance among the two points as shown in the photo above by the
