    摘要: A temperature calculation system includes a yoke disposed along an inner circumference, first and second teeth arranged on an inner circumference surface of the yoke while having an interval set in a circumference direction, and a coil member formed between the first and second teeth and including a plurality of coils, forms a thermal equivalent circuit of the coil member, and calculates a temperature of a set portion of the coil member. An outer circumference surface temperature and an inner circumference surface temperature of the coil member are calculated by using radial conduction resistance using a temperature of an inner one side of the coil member. An average temperature of the coil member is calculated by using compensation resistance from the temperature of the inner one side of the coil member, thermal capacity of the coil member, and a heating amount of the coils formed in the coil member.

    摘要: A stator for a motor that includes an armature coil that generates an N-pole and an S-pole by applying a current and forty-eight slots radially formed at which the coil is disposed and in which the armature coil alternately implements N-poles and S-poles by arranging six slots as a single unit as the current is applied to the coil. The slot includes a plurality of phase drawing out slots, and when the order of the phase drawing out slots is determined in a clockwise direction by setting one phase drawing out slot as a first phase drawing out slot, at least two methods of winding the armature coil to turn around the slot may be used to decrease a distance from the first phase drawing out slot to the last phase drawing out slot to a minimum value by setting a cell between neighboring slots as a unit.

    摘要: A stator of an interior permanent magnet synchronous motor is provided. The stator spaced apart from a rotor by a predetermined gap within an interior permanent magnet synchronous motor includes a stator tooth that is circumferentially spaced apart by a predetermined distance while interposing a slot therebetween that corresponds to an exterior diameter surface of the rotor. Additionally, a stator shoe is formed at an end of the stator tooth and includes an interior diameter surface of a predetermined diameter that faces the exterior diameter surface of the rotor. A cross point between a circle has a diameter of (interior diameter of the stator shoe×1.0287×24/slot number) mm and the stator tooth is a tooth end start point of the stator tooth.
