The rotor includes a rotor core having an outer circumferential surface extending about the rotation axis and a plurality of permanent magnets attached to the rotor core to form plural poles along the outer circumferential surface of the rotor core. The outer circumferential surface of the rotor core is provided, at each pole, with a contour deviating from a circular arc and bulging out in a radial outward direction, as seen in a cross-section perpendicular to the rotation axis. The permanent magnets include a plurality of magnet sets individually assigned to the plural poles, each set including two or more permanent magnets. The contour of the outer circumferential surface of the rotor core, at each pole, has at least partially a shape represented by a hyperbolic cosine function or a secant function.

摘要： A method of expanding types of synchronous motors capable of reducing the number of required stator types to use stators in common, and a synchronous motor produced by the method. A group of stators are prepared by stacking stator cores of identical shape so that heights of the stators are different from one another to be multiples of a fundamental height. A plurality of groups of rotors are prepared so that lengths of the rotors in each group are different from one another to be multiples of a fundamental length. The rotors in each group are provided with permanent magnets having a residual magnetic flux density different from that of the permanent magnets of the rotors in the other groups. A stator and a rotor corresponding to a preset output torque specification value and a preset rotor inertia specification value are respectively selected from the group of stators and the rotor groups and are combined with each other, whereby an expanded type of motor is obtained.

摘要： A cable clamp for clamping a motor cable includes a fixing member having a pair of bottom plates. The bottom plates are placed in parallel to each other to thereby define an opening. A pair of guide members are also placed in parallel to each other and bridge the bottom plates to further limit the opening. The motor cable is then received through the opening. A slide member slides along the pair of guide members to thereby clamp the cable. The bottom plates may optionally include a depression near the opening which defines a recess. A waterproof adhesive may be disposed within the recess to thereby form a watertight barrier.

摘要： There are provided a strength evaluation method of a die casting product capable of appropriately evaluating the strength of the die casting product, and a die casting product in which the strength is evaluated by the strength evaluation method. A breakage test is performed by a simple strength tester after casting, and then, a strength reduction ratio is estimated based on an area ratio of cold flakes in a broken surface obtained by broken surface observation. Alternatively, ultrasonic flaw detection is performed for an internal defect in a predetermined range of a high stress portion of the die casting product, calculated by stress analysis in advance, and the die casting product is evaluated to have a predetermined strength when a defect ratio obtained by dividing a total area of the internal defect in the predetermined range by a total defect detection area is less than or equal to a predetermined value.
