<p>PURPOSE:To suppress wave noise generated from power cables and electrical equipments mounted on a car body, by earthing shield cases and casings to the car body respectively via earth members. CONSTITUTION:The peripheries of a controller 10 for controlling a power steering device in motor operation system and a motor 2 are respectively covered with magnetism shielding casings 14, 16. The casings 14, 16 are earthed to a car body via the earth members of a low high-frequency impedance, for example, braided wires 18, 26, respectively. In the meantime, to the power input section of the controller 10, power is to be fed from a battery 26 via power cables 22, 24. The peripheries of the respective power cables 22, 24 are covered with shield cables 28, 30, and the shield cables 28, 30 are earthed to the body via braided wires 32, 34, respectively.</p> |
