EASA CURRENTS May 2008 3 Identifying Unmarked Leads Of 6-Lead Motors With 1 Or 2 Windings Procedures Also Help Identify Type Of Connection When There Is No Nameplate
A “Y” motor should have continuity through wires 1 and 4, 2 and 5, 3 and 6, and through 7 to 8 to 9. If there is not continuity through any of the wiring sets then you have an open winding, and the motor is bad. Use the “Delta” drawing for motors wired with a “Delta” connection, following the example of “Y” for lead continuity. Also verify each winding set has NO continuity to ground, if any
