Abstract:
1. A motor configured to receive power from a power source, the motor comprising: a motor housing; a stator at least partially disposed within the motor housing and supported by the motor housing; a rotor disposed to magnetically interact with the stator, the rotor comprising a shaft supported by the motor housing, the shaft defining an axis and being disposed to extend beyond the motor housing in an axial direction; a motor diagnostic indicator circuit electrically connected to the power source to receive an input power, the motor diagnostic indicator circuit being supported by the motor housing, and adapted to determine and display at least one of a proper power connected condition, an over-voltage connected condition, and an under-voltage connected condition based on comparing the input power to a reference property; and a thermal protector connected to a stator winding and operable to provide a voltage in an open condition to the motor diagnostic indicator circuit, the motor diagnostic indicator circuit further adapted to determine and display a thermal protector open condition based on the voltage.
