Abstract

DC60 (27/01/46) To guarantee dielectric strength between conductors at the ends of the windings, the first conductor at the section The ends of such windings are arranged so that they are crossed with two adjacent conductors. In the radial direction at one or more conductors-electrical points, a concave direction is established in the radial direction in the lateral surface. Which is the surface on the opposite side Together in the conductors that Are located opposite each other along any intersection where the concave part will have a depth that Increases as it approaches the near end of the conductor, therefore, the clearance Clearly enough Between the conductors near the ends of these conductors, where the insulating membranes are damaged. Easily cured due to heat exposure, thus, it gives the electrical insulation certainty and is Improving the efficiency of Improved cooling at the ends of the windings to guarantee dielectric strength between conductors located at the ends of the winding. The ends of such windings are arranged so that they are crossed with two adjacent conductors. In the radial direction at one or more conductors-electrical points, a concave direction is established in the radial direction in the lateral surface. Which is the surface on the opposite side Together in the conductors that Are located opposite each other along any intersection where the concave part will have a depth that Increases as it approaches the near end of the conductor, therefore, the clearance Clearly enough Between the conductors near the ends of these conductors, where the insulating membranes are damaged. Easily cured due to heat exposure, thus, it gives the electrical insulation certainty and is Improving the efficiency of Better cooling at the end of the coil
