October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Bench Testing: Rotor
- Check rotor for open field windings by using an ohmmeter across slip rings. Rotor resistance should be within specification. See ROTOR RESISTANCE SPECIFICATIONS table.
- Check rotor for shorts to ground by connecting ohmmeter between slip ring and rotor shaft. Ohmmeter should indicate no continuity. Check slip rings for wear or pitting. Standard slip ring diameter is .559-.567" (14.2-14.4 mm). Turn slip rings on lathe if necessary. Minimum slip ring diameter is .504" (12.8 mm).
