摘要： To reduce torque ripples appearing in an output torque of an electric synchronous motor, the rotor (10) is divided into 2.sup.n rotor elements (101, 102, 103, and 104) the rotor elements of each of 2.sup.n-1 pairs of rotor elements (101, 102; 103, 104) being circumferentially shifted from one another around an axis of the rotor by an angle corresponding to a half of the wavelength (.lambda.) of a first (A) of "n" kinds of cyclic torque ripples (A and B) to cancel the first kind of torque ripple, and the 2.sup.n-1 pairs of rotor elements (101, 102; 103, 104) being arranged to be grouped in 2.sup.n.sup.-2 sections of rotor elements, each section including two pairs of rotor elements, and the 2.sup.n-2 sections of rotor elements being circumferentially shifted from one another around the axis of the rotor by an angle corresponding to a half of a wavelength (.lambda.) to cancel a second of the "n" kinds of torque ripple, and eventually, the rotor structure being structured so that the rotor elements are further circumferentially shifted from one another to cancel the "n"th torque ripple component.

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 rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.

摘要： An electric current control method for a servomotor in which a reactive current is lowered in a region where a voltage saturation does not occur, to suppress generation of heat caused by the reactive current and achieve a stable rotation up to a high-speed region. In the current control of the servomotor using a DQ conversion, an electric current is not supplied to d-phase and supplied only to q-phase when a rotational speed of the servomotor is not high, and the reactive current is supplied to the d-phase only when the rotational speed of the servomotor is high, to thereby lower the terminal voltage of the servomotor by the reactive current. Thus, the reactive current is reduced in the region where the voltage saturation does not occur, to thereby suppress the generation of heat due to the reactive current, and also achieve the stable rotation even in the high-speed region.
