Abstract: PURPOSE:To reduce high-frequency components transferred from a winding to a field system by a method wherein an insulating body, consisting of a material having a low dielectric constant, is interposed between the field system and the winding, in a motor driven by an inverter. CONSTITUTION:An insulating body I is interposed between the field system 24 and the winding 25 of a motor 21 by a method wherein the field system 24 is formed on the inner periphery of a motor casing 23 and the side surface of the field system 24 is surrounded by the insulating body I, made of a resin such as polypropylene or the like and consisting of a material having electric insulating property and a low dielectric constant, while the winding 25 is wound around the outer periphery of the insulating body I. In this case, high-frequency component, generated in an inverter driving the motor 21, is transferred to the winding 25 and tries to be transferred to the field system 24 through floating capacity, however, the insulating body I is interposed between the field system and the winding whereby the floating capacity between the field system and the winding is reduced and high-frequency impedance between both of them is increased. Accordingly, the level of the high-frequency component, transferred from the winding to the field system, may be reduced remarkably.
