TH59293A - Insulated cover structure for rotary machinery. - Google Patents

Abstract

The DC60 aims to improve the winding speed and productivity of rotary machines by incorporating curved edges on the corners of the insulating body tongues. In the structure of the insulating body tongue for rotary machines, the corner tongues positioned in the stator or rotor core are constructed to have curved edges, resulting in a winding locus that is closer to a circle than a rectangular shape as typically seen. This allows for increased winding speed.

Claims (9)

1. An insulating enclosure structure for a rotary machine in which the windings are wound around the stator core of the rotary machine through an insulating enclosure body constructed in a ring shape, which consists of tongues built on the inside or outside of the insulating enclosure body and extending in the axial direction of the stator core. The tongues are arranged at an angle with curved edges, forming a bow-like or C-shaped shape, where the tongues are shaped in such a way that the curved edges enclose a circular path. 2. Insulating cover structure for rotating machinery as specified in Claim 1, where the rotating machinery shall be a resolver. 3. Insulating cover structure for rotary machinery as specified in Claim 1, where the insulating cover body shall be a pair of insulating covers. 4. Insulating cover structure for rotary machinery as specified in Claim 1, where the insulating cover body is integrated with the stator core using resin. 5. Insulating cover structure for rotary machinery as specified in Claim 1, where the insulating cover body shall be a pair of insulating covers. 6. Insulating cover structure for rotary machinery as specified in Claim 2, where the insulating cover body is integrated with the stator core using resin. 7. An insulating cover structure for rotary machinery as specified in Claim 1, where the reed is shaped in such a way that when a coil is wrapped around the reed with a needle, the rotational path of the needle creates a circular shape. 8. Insulating cover structure for rotary machinery as specified in Claim 1, where sequential valves include magnetic poles. 9. An insulating cover structure for rotating machinery as described in Claim 1, where each curved edge touches a circular path in such a way that the distances between contact points are equal.
