High-withstand voltage rectangular wires are effective in motors with a higher design voltage than that of existing motors, and are applicable to drive motors for electric and hybrid vehicles. They have been invented as wires that will help to miniaturize such drive motors.

Structure

As shown in the diagram, the wire is composed of a rectangular conductor, an enamel layer and an extruded resin layer.

Relationship between film thickness and electric characteristics

Features and advantages

  • Advanced insulation characteristics open the way for application to high voltage drive purposes. By omitting the inter-layer insulation paper, they contribute to the shortening of the process and the downsizing of equipment.
  • A rectangular shape means a high space fill. It leads to enhanced efficiency and reduced weight.
  • A highly heat-resistant enamel layer provides the wires with excellent heat resistance and reliability.
