摘要： A squirrel-cage rotor 10 includes a plurality of slots 16 for accommodating secondary conductors 18 along the outer circumferential surface of a laminated core 14 fixed to a rotor shaft 12. Each slot 16 is defined by a wall having a generally elliptical profile in which a maximum circumferential distance D is larger than a maximum radial distance d in a given section orthogonal to an axis and axially penetrates near the outer circumferential surface of the laminated core 14. The radial inner profile of the slot 16 has a shape in which the tangents on given two points adjacent to the radial innermost portion of each slot wall do not cross at an acute angle in a section orthogonal to the axis, in order to prevent a stress concentration.

摘要： A method and apparatus for controlling an induction motor having at least high speed windings and reduced speed windings divides the reduced speed windings into first and second portions. The first and second portions of the reduced speed windings are electrically connected in series and a voltage is applied to the first and second portions of the reduced speed windings when it is desired to operate the induction motor at a reduced speed. The first and second portions of the reduced speed windings are electrically disconnected and a voltage is applied to the high speed windings when it is desired to operate the induction motor at a high speed. The induction motor has three sets of windings extending from a middle region, each set of windings having an inner winding toward the middle region and an outer winding away from the middle region. According to one aspect, a first changeover circuit is electrically connected to each set of windings, between the inner and outer windings for applying a voltage to the outer windings when it is desired to operate the induction motor at a high speed. A second changeover circuit is electrically connected to each set of windings, toward the middle region from the inner windings for applying a voltage to the inner and outer windings when it is desired to operate the induction motor at a reduced speed. It is thus possible to change from a Y configured winding connection to a .DELTA. configured winding connection.

摘要： A molding process for coating a motor stator (1) having coils (2) projecting outside from the opposite ends of the motor stator (1) with a synthetic resin. The stator having coils (2) projecting from the opposite ends thereof is placed in an upright position in combination with a built-up mold core. The synthetic resin is poured from the upper end of the mold core and the initially poured resin flowing around the outside of the coil projecting downward is discharged together with gas. The stator is thus coated entirely with the resin containing only a few pores through a single molding cycle. The stator can be readily separated from the mold core.

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).
