摘要:
A method of and apparatus for inserting coils into slots formed in the stator core of a dynamoelectric machine such as an electric motor, with the stator core having open type slots each of which cooperates with blades of the apparatus for guiding the coil and a stripper for forcing the coil out of the blades. A closed space has a volume sufficient to avoid any disorder of coil wire layers when the coil is received by the closed space. After placing the coils in the closed spaces, the coils are pushed into the respective slots and, as desired, the coils are further compressed until the coil wires assume a non-circular cross-section. By so doing, it is possible to remarkably increase the space factor of each slot.

An electric wire is wound as coil turns in slots in electric rotating machinery component such as a stator or an armature. The wire as it is supplied from a nozzle or flyer is guided by movable formers into successive layers of coil turns in the slots without forming an unwanted dead space in the slots. The formers are moved in radial increments to provide successive spaces in the slots for allowing the successive coil turn layers to be neatly laid in the spaces.

When performing supply and measurement of various signals on n=8 semiconductor IC devices under test DUT1-DUT8 using m=3 substrates 10-30, reference voltages of the devices under test DUT1-DUT3 are input to the substrate 10, reference voltages of the devices under test DUT4-DUT6 are input to the substrate 20, and reference voltages of the devices under test DUT7 and 8 are input to the substrate 30. The reference voltages input to each substrate 10-30 are averaged. The mean voltages made in each substrate are further connected to each other, and a reference voltage is made using three substrates 10-30. The reference voltage is used as a reference voltage for voltage generating circuits 11-31. The reference voltage having no variation among each substrate is set even if the number of semiconductor IC devices under test is increased and the whole equipment becomes large.
