Abstract: A method for regulating a coupling formation includes sensing a temperature of a coupling with a non-contact sensor and sending the temperature to a control unit that regulates the temperature of the coupling formation. In addition, a system for regulating a temperature of a coupling formation includes a temperature control unit and a non-contact sensor in flow communication with the temperature control unit.

Abstract: A system for motor thermal protector device performance test data collection includes a microprocessor configured to measure elapsed times of reset and trip power cycles of a motor winding through a thermal protector device. An operator interface terminal is coupled to the microprocessor and includes a display and input selectors for recalling a predetermined number of elapsed reset and trip times stored in a system memory.

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).
