<p>PURPOSE:To operate a thermal protector positively, and to prevent burning by winding tap winding for changing over 50Hz or 60Hz, winding common winding on the tap winding and mounting the thermal protector on the common winding while contacting the protector with the common winding. CONSTITUTION:When a coil is wound on the bobbin 3 of a shading coil induction motor, the tap winding 5 for changing over 50Hz or 60Hz is wound first, and the common winding section 4 of 50Hz and 60Hz is wound on the tap winding. The thermal protector 6 is mounted to the surface of the common winding. Accordingly, the thermal protector can positively be operated even to the defective connection of 50Hz or 60Hz.</p> |
