    摘要: With a view to reduce vibrations generated by a motor and improve resistance to heat, reliability and vibration isolation properties without increasing the cost or the number of manufacturing steps in a rotor for a permanent-magnet motor, a rotor core is formed of an outer peripheral portion by which the permanent magnet is fixed, and a central portion by which a shaft is fixed, a clearance is provided between the outer peripheral portion and the central portion, and the outer peripheral portion is connected to the central portion by means of a plurality of fastening members. Thus, a rotor having excellent vibration isolation properties can be obtained. Since the rotor core is formed of laminated iron plates on which the outer peripheral portion, the central portion and the fastening members are all formed as one piece, resistance to heat, reliability and the vibration isolation properties can be enhanced without increasing the cost or the number of manufacturing steps.

    摘要: The object of the present invention is to provide a low-noise and low-vibration brushless motor and an electric applicance and a vehicle which have the brushless motor and increase in quietness, by optimizing a ratio of the number of poles on a rotor to the number of slots on a stator, the ratio being suitable for a driving circuit. The present invention is a brushless motor constituted by ten-pole rotor (1), a stator (3) having (12) slots (2) and making three-phase connection to the slots (2), and a driving circuit (5) for applying three-phase full-wave current to the stator (3). Further, the conduction width of the driving circuit is set at an electrical angle of 135 to 180°.

    摘要: A stator core which assures a favorable workability for coupling core segments and has favorable magnetic characteristics even when made by coupling core segments that are formed by laminating core division sheets. A method of manufacturing a core for rotary electric machines includes forming a coupling convexity having an arc-like planar shape and a coupling concavity engageable with the coupling convexity on core segments, forming a serial core segment assembly by engaging the coupling convexity on one of the core segments with the coupling concavity formed on an adjacent core segment so as to be rotatable by more than 180 degrees, and forming a magnetic circuit by bending the serial core segment assembly into an annular form.

    摘要: A collision energy absorbing structure of a vehicle body upper portion of an automobile having a roofside rail (20) extending in the forward and backward direction and formed to be a closed structure with an outer panel (30) and an inner panel (32) includes a metal energy absorbing panel (22) and a resin interior trim material (24). The energy absorbing panel (22) has a thickness smaller than the thicknesses of the outer panel (30) and the inner panel (32) and is arranged with a space (D) inward of the inner panel. The terminal portion in the longitudinal direction of the energy absorbing panel (22) has a tendency that energy absorption reduces but the tendency is compensated by resin material (26, 28).
