摘要： PROBLEM TO BE SOLVED: To suppress vibrations and noises excited by the radial electromagnetic vibration force of a motor. SOLUTION: The motor 100 is constituted as follows. A rotor 1 is divided into four rotor pieces 3, 4, 5, and 6 to the shaft length 2L of a group of rotor cores. For example, it is idealistic that each effective pole open angle of the four rotor pieces 3, 4, 5, and 6 is 0.29L, 0.71L, 0.71L, and 0.29L of the axial length, respectively. Further, a permanent magnet 2 of each rotor piece 3, 4, 5, and 6 is arranged so that a phase difference of the electric angle respectively becomes 0, π, 0, and π in the circumferential direction of the rotor 1. Also, when it is effective even if the idealistic shaft length is changed, the tolerance is made to ±0.1L to the shaft length. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a stator structure of an electric motor that reduces an electromagnetic excitation force between a rotor and a stator, and resonance of the vibration mode of a structure system, and that, as a result, solves the vibration problem of the electric motor.
SOLUTION: The stator structure of an electric motor consists of the rotor and the stator structured by stacking plate-like stator cores. A deformation shape to the excitation force is changed to a mode other than the zero-order of a circular ring, by making uneven the strength in the circumferential direction of each stator core 2 making up of the stator 1. Furthermore, at least two stator cores 2 are shifted to each other in the circumferential direction and stacked, so that the deformation of each stator core 2 becomes a reversed phase corresponding to the mode other than the zero-order of the circular ring of the deformation.

摘要： PROBLEM TO BE SOLVED: To improve cooling efficiency by effectively cooling around the heavily heating center portion of the direction of a rotating shaft of a rotor.
SOLUTION: This electric motor is made up of the rotor 4 of an electric motor 1, a shaft 8 that becomes the rotating shaft, a ring 9 fixed to the roughly center portion of the shaft 8, and a pair of rotor cores 10 arranged at both sides of the direction of the rotating shaft sandwiching the ring 9. A plurality of louvers 15 are cut penetratingly in a pair of the rotor cores 10, and recessed portions 12 are formed on the outside circumferential surface of the ring 9. These louvers 15 are communicated with the recessed portions 12 to make a cooling air path. Then, a distance L2 from the opening positions of the recessed portions 12 to the shaft is made larger than a distance L1 from the opening positions of the louvers 15 to the shaft. By causing a pressure difference between the positions, cooling air taken into the louvers 15 when the rotor 4 is rotated is configured to flow toward the recessed portions 12 and to concentrate on the vicinity of the center portion of the rotor 4.

摘要： PROBLEM TO BE SOLVED: To provide a stator structure of a motor improvable in radiation efficiency by a cooling medium, and to provide a manufacturing method of a motor stator.
SOLUTION: The stator structure of the motor is formed with a slot, impregnates varnish 8 into a coil 6 after inserting the coil 6 into the slot, and cures the varnish by heating. The varnish surface of the coil end of the coil 6 is made large by being formed into an irregular shape such as, for example, a crater shape. By this, when cooling the structure by using the cooling medium, the flow of the cooling medium on the surface can be turbulized, whereby cooling efficiency is improved.
