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.

Method and system for regulating a temperature of coupling formations

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.

Apparatus and method for collecting motor test data

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).

Non-contact coil form measurement and control apparatus for measuring the spread of a coil forms includes a bar code scanner for determining the relative positions of the coil forms. More particularly, the bar code scanner is mounted to the winding machine at a location which enables the scanner to scan both forms. The scanner may be coupled to the winding machine controller which controls operation of the winding machine. A target, such as a bar code, is positioned on each coil form. In operation, when a particular stator configuration is to be fabricated, the operator enters the stator configuration identification into the winding machine controller. The scanner then scans the bar codes located on the forms to determine the coil form separation. In the event that the coil forms are incorrectly set, the controller interface informs the operator of this condition and instructs the operator to set the coil form spread. Once the operator has reset the coil form spread, the operator enters a command into the winding machine controller which results in the bar code scanner once again scanning the coil forms. The above process is repeated until the coil forms are set at the correct spread. When the forms are set to the correct spread, then winding operations can continue.

Apparatus and methods for non-contact coil form spread measurement

An apparatus and method for testing a coating on a conductor, such as a dielectric coating on a wire. A high voltage source is coupled to the conductor and the coating through a primary winding of a transformer. Faults in the coating will result in a change in current in the primary winding thus inducing current in a secondary winding of the transformer. Current in the secondary winding is detected by a sensor and fault data can be compiled by known data acquisition devices.
