Title:

COIL FOR SEALED TYPE DRIVE MOTOR AND ITS MANUFACTURING METHOD

Document Type and Number:

Japanese Patent JP2009112159

Kind Code:

A

Abstract:

To provide a coil for a sealed type drive motor suppressing a breakdown or the like at a high temperature and having an excellent reliability.

In the coil for the sealed type drive motor, a thermosetting-resin composition is subjected to vacuum-pressure impregnating treatment to a winding body winding an insulating tape on the outer periphery of a coil wire. In the coil for the sealed type drive motor, the thermosetting-resin composition contains (a) a dimaleimide compound, (b) an epoxy resin, (c) an isocyanuric-acid derivative having at least one functional group having an unsaturated bond and (d) an acid anhydride as essential ingredients. In the coil for the sealed type drive motor, a heating loss in 24-hour treatment at 300C after curing is 10% or less in the thermosetting-resin composition.
