摘要： This method is for manufacturing the cage rotor of an induction motor comprising a plurality of secondary conductors arranged in a plurality of through holes (16) of a laminated core (14), and a pair of end rings for connecting the secondary conductors to each other on both ends of the laminated core (14) in the axial direction. Each of a pair of reinforcing members (22) comprises a cylindrical wall (26), an annular multihole wall (28) having a plurality of holes (32) and extending radially inwardly from the edge of one end of the cylindrical wall (26), and an annular end wall (30) extending from the other edge of the cylindrical wall (26) radially inwardly and approximately in parallel with the multihole wall (28). Each of reinforcing members (22) is arranged on both end faces of the laminated core (14) in the axial direction, respectively in such a manner that each of them contacts each multihole wall (28) and the through holes (16) communicate with the holes (32). In this state, the laminated core (14) and the reinforcing members (22) are fixedly supported by a jig (34), and then, arranged in a mold (36). When casting, a molten metal is poured into a continuous cavity including the annular spaces in the reinforcing members (22), the holes (32) of the multihole wall (28), and the through holes (16) of the laminated core (14) through the central opening (31) of the end wall (30) of one reinforcing member (22a) arranged on the pouring gate (58) side. At the same time, the gas in the cavity is exhausted through the central opening of the end wall (30) of the other reinforcing member (22b).

摘要： A cooling liquid flow path (30) is extending in an axial direction inside a laminate stator core (14), and cooling liquid communication paths (32 and 34) are formed in front and rear housings (20, 22) clamping the laminate stator core (14) between them in such a manner as to dispose one continuous cooling liquid path in a motor (1). An exciter winding (16) wound on the laminate stator core (14) is covered with a heat transfer member (42) made of a heat conductive composite resin material. The heat conductive composite resin material is obtained by mixing a resin material having high heat resistance and moldability with an electrically insulating granular material having high heat conductivity such as aluminum oxide. The heat transfer member (42) is in thermal contact with the exciter winding (16), the inner wall surface of a slot of the laminate stator core (14), and the inner wall surfaces of the front housing (20) and the rear housing (22).

摘要： For a recent motor requiring larger output and torque, liquid-cooling is preferable for increasing cooling efficiency and, because of simplicity of construction, the so-called jacket system is employed for cooling the stator (17). The conventional jacket system, however, lowers cooling efficiency on account of a cylinder member interposed between the stator (17) and the jacket (18). In this invention, therefore, an adhesive is applied to the entire surface or a partial annular surface area (Z1) of each of laminations (16) composing the stator (17) and, with the laminations assembled, cooling liquid is prevented from entering the inner periphery of the stator (17) and thus a liquid passage (24) of the jacket (18) can be adapted to directly face the outer periphery of the stator (17).

摘要： The stator of a built-in motor must be correctly secured to the spindle head housing of a machine tool. For this purpose, the periphery of a stator core (10) which is a main portion of the stator is partly welded and is held by a mandrel or the like from the inside to grind the outer circumference (14) maintaining precision. After the mandrel and the like are removed, however, the stator core (10) may undergo deformation with the passage of time. To prevent this, a thermosetting adhesive is applied to the surface of the constituent element plates (12) of the stator core (10) to bond them together, or the constituent element plates (12) are provided with a protuberance (22) as the outer circumference (14) is welded to bond them together, or a serration bar (26) is forcibly inserted in a hole (24) of the element plates (12) instead of providing the protuberance (22) to bond them together.

摘要： This invention is directed to efficient cool a rotating member under an environment where it receives an excessive heat transfer, such as a main spindle equipped with a built-in motor. The rotor (12) of a built-in motor is directly fitted to the rear end side of a main spindle (10) of a machine tool, and the stator (14) is so disposed on a spindle housing (16) encompassing the main spindle (10) as to encompass the rotor (12). A ring-like member (18) is fixed to the inner peripheral surface of the spindle housing (16) in front of the stator (14), and encompasses the main spindle (10) with a suitable gap. A magnetic fluid (20), for example, a mixture of fine powder of iron oxide and a liquid such as water or a mineral oil, is filled into the gap defined between the main spindle (10) and the ring-like member (18). A cooling liquid passage (22) is disposed in the spindle housing (16) in the proximity of the stator (14) and the ring-like member (18).
