ABSTRACT:
Apparatus and methods for inspecting electrical connections so as to determine the presence of fault connections between magnet wires and power leads are described. The apparatus includes a processing unit, a power supply unit, and a temperature sensing unit. The processing unit includes a programmable logic controller (PLC) having a central processing unit (CPU) and a plurality of input and output slots. The power supply unit includes a power lead connector configured to couple to the motor power leads and a power relay coupled to the PLC. The temperature sensing unit includes infrared thermometers to determine the temperature at the electrical connections between the stator magnet wires forming the motor windings and the power leads. The outputs of the thermometers are coupled to the programmable logic controller (PLC).
