摘要： PROBLEM TO BE SOLVED: To provide a configuration of a brushless motor system capable of improving an adverse effect of electromotive noise without need for enlarging a filter or high performance. SOLUTION: In this brushless motor system equipped with a brushless motor, an inverter device and a DC power supply, a noise circulation line for circulating noise current is connected to between the brushless motor and the inverter device. The noise current occurs in the inverter device and reaches the brishless motor. Attachment of the noise circulation line can reduce a common mode current leaking from the brushless motor to the ground. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce inductance in a capacitor unit formed by connecting in parallel a plurality of capacitor elements.
SOLUTION: Plate type anode conductors 9a, 10a and cathode conductors 9b, 10b are allocated in the upper and lower sides of a plurality of capacitor elements arranged. An insulating layer 12 is inserted between the anode conductors and cathode conductors. Lead wire of each capacitor element connects plate type conductors so that polarity is inverted from that of the adjacent capacitor element. For example, the anode lead wire 6a of the capacitor element 5 is connected to the anode conductor 9a passing through the cathode conductor 9b and insulating layer 12. Moreover, the cathode lead wire 6b is connected only to the cathode conductor 10b, and a hole 11 is opened between the anode conductor 10a and the insulating layer 12. Meanwhile, each lead wire of the capacitor element 7 is connected to the anode conductor 10a and cathode conductor 9b to provide the polarity inverted from that of the capacitor element 1.

摘要翻译：要解决的问题：减少通过并联连接多个电容器元件形成的电容器单元中的电感。解决方案：板状阳极导体9a，10a和阴极导体9b，10b分配在布置的多个电容器元件的上侧和下侧。绝缘层12插入在阳极导体和阴极导体之间。每个电容器元件的引线连接板型导体，使得极性与相邻的电容器元件的极性相反。例如，电容器元件5的阳极引线6a与通过阴极导体9b和绝缘层12的阳极导体9a连接。此外，阴极引线6b仅与阴极导体10b连接，在阳极导体10a和绝缘层12之间打开11。同时，电容器元件7的每个引线连接到阳极导体10a和阴极导体9b，以提供与电容器元件1的极性相反的极性。
