摘要： A reactor (32) and a switch (35) are interposed in parallel between U-phase, V-phase and W-phase on a power source side (31) and U, V and W terminals on a motor side (33). A changeover switch )37) is interposed between Z, X and Y terminals on the motor side (33) and the U, V and W terminals on the motor side (33). When the switch (35) is set to OFF, the changeover switch (37) is set to ON, and the switch (35) is set up so as to interconnect Z, X and Y terminals, windings of the motor are set up in the form of Y-connection, so that the motor and a power source are connected directly to each other. On the other hand, when the changeover switch (37) is switched over to OFF, and the switch (35) is set up so as to interconnect Z, X and Y terminals to the U, V and W terminals, the windings of the motor are set up in the form of &Dgr;-connection, so that the motor and the power source are connected together through the reactor (32).

摘要： A method of producing a squirrel-cage rotor for an induction motor, which includes a plurality of secondary conductors arranged respectively in through holes (16) of a laminated core (14), and a pair of end rings connecting the secondary conductors with one another at both axial ends of the laminated core (14). Each of a pair of reinforcing members (22) includes a cylindrical wall (26), an annular multi-aperture wall (28) provided with apertures (32) and extending in a radial inward direction from one edge of the cylindrical wall (26), and an annular end wall (30) extending generally parallel to the multi-aperture wall (28) in a radial inward direction from another edge of the cylindrical wall (26). Each reinforcing member (22) is arranged in a manner in which the multi-aperture wall (28) is brought into contact with one of the axial end faces of the laminated core (14) while the apertures (32) communicate with the through holes (16). In this state, the laminated core (14) and the pair of reinforcing members (22) are fixedly supported by a jig (34) and placed in a mold (36). In the casting process, molten metal is poured into a continuous cavity from a center opening (31) of the end wall (30) of one reinforcing member (22a) disposed near a gate (58), while gas in the cavity is discharged through a center opening (31) of the end wall (30) of another reinforcing member (22b).
