AXIAL BRUSHLESS MOTOR

摘要

PURPOSE:To make the direction of the current through an air-core coil constant even if the electric connecting terminal part is electrically connected to the electric connecting part of a printed board by constituting the device of a printed board having the electric connecting part so as to cover both the inner and outer surfaces of the stereoscopic region of an air-core coil. CONSTITUTION:The current from an input terminal 9 runs through an electric connecting part 6 in the clockwise direction along the inner side of an air-core coil 1 and is outputted through the electric connecting part 6. Under the state wherein the air-core-coil mounting surface is inverted, the current from the input terminal 9 runs through the electric connecting part 6 in the clockwise direction along the outer surface side of the air-core coil 1 and is outputted through the electric connecting part 6. Thus, the direction of the current through the coil 1 becomes constant in this constitution even if the coil mounting surface is inverted by constituting the electric connecting part 6 so as to cover both ends of the inner surface part and the outer surface part of the stereoscopic region of the air-core coil 1.
