Reduction insulation structure suitable for high-voltage motor and insulation processing method thereof

The invention discloses a reduction insulation structure suitable for a high-voltage motor and an insulation processing method thereof. The reduction insulation structure comprises a plurality of low resin mica tapes (2) lapped outside an electromagnetic coil (1), and is characterized in that vacuum dipping treatment is carried out by utilizing vacuum pressure dipping resin after the low resin mica tape is lapped, and the insulation structure with reduced insulation thickness is formed after baking and curing. The breakdown voltage of the insulation structure is qualified, the normal dielectric loss, the thermal state dielectric loss, the dielectric loss increment and the electrical strength of the insulation structure reach high grade.
