across each pair of stator windings if the rotors of the units are not at the exact same angle relative to the stator phases. This causes current to flow in both stators, producing a torque on each rotor. 2-1 2.1 Theory of Operation and Classic Applications A synchro functions as an electromechanical transducer

If motor protection is not adequate, the stator winding can fail, and the squirrel cage rotor may be damaged or destroyed. The standard three overload starter should not be relied on to provide protection against single phasing. One reason for this is that local internal winding overheating can still occur even when line currents do not
