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： Structure of a rotor which is designed to reduce the slot ripple so that a synchronizing AC servo motor is allowed to turn smoothly. Namely, two rotor elements (30, 30') are arranged in parallel with their angular positions being deviated from each other in the rotational direction by a mechanical angle (θ) that corresponds to the half-wavelength of a slot ripple wave that generates in the rotor of the conventional construction. There can thus be provided a rotor structure in which the slot ripple waves generated by the rotor elements (30, 30') cancel each other.

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).

摘要： A cage rotor (10) includes a plurality of slots (16) for accommodating secondary conductors (18) along the periphery of a laminated core (14) fixed to a rotor shaft (12). The slots (16) pass through the core (14) in parallel with the rotor shaft, and their cross sections in a plane perpendicular to the rotor shaft are shaped substantially like an ellipse elongated along the periphery of the core, of which the major axis is D and the minor is d. To avoid stress concentration, the profile of the slot (16) has a shape such that tangential lines at given two adjacent points closest to the center of the core do not make an acute angle on the section perpendicular to the axis.

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).
