Abstract
An electric motor comprising a stator having a plurality of radially inwardly extending circumferentially spaced polar segments. A coil is wound around each stator segment. A unitary motor overload assembly is provided and connected by a standard lead from one of the coils and by a solid uninsulated conductor lead to the other of the coils. The cross-section of the solid conductor is such that the motor will operate satisfactorily during normal running or locked rotor condition but would open by melting in the event of a winding failure of the coils which would normally result in higher than normal operating currents in the winding.
