The invention relates to a low-
voltage efficient motor
high heat conduction and insulation structure and a manufacturing method thereof. The insulation structure in a motor comprises a
stator iron core, a slot wedge, and
motor insulation paper, wherein the
stator iron core is a
high heat conduction
stator iron core with a winding, the iron core is of a
high heat conduction compound insulation paste impregnating insulating structure, the slot wedge is of a high heat conduction drawing slot wedge insulation structure, and the
motor insulation paper is high heat conduction compound insulation paper. The method for manufacturing the high heat conduction compound insulation paste, a drawing slot wedge, the high heat conduction compound insulation paper and the high heat conduction stator core dipping with the winding is provided according to the insulation structure. Due to the fact that the high heat conduction insulation compound paste is used in the low-
voltage motor stator iron core, the slot wedge and the
motor insulation paper, the heat conduction coefficient of the low-
voltage motor can be improved to 0.3-0.4163W / (m. k), and the insulation meets the F level and H level motor insulation requirements. The purposes of reducing the motor loss, improving efficiency and reducing the heat emitting quantity and temperature rising are achieved. The stability and the reliability of working of the
machine can be improved, and the service life of the motor is prolonged.
