THERMALLY RESPONSIVE PROTECTION APPARATUS FOR ELECTRIC MOTORS |
摘要 |
<p>A thermal protection mechanism for electric motors includes a pair of spaced contacts secured to an electrically insulating carrier having a cavity and a surface adjacent to a motor winding. The surface of the carrier has an aperture that forms a thermal passage between the surface of the carrier and the cavity. The contacts are engaged with a fusible electrically conductive pin made of solder that is disposed within the cavity and that interposes along a current path to the windings of a motor. A high winding temperature causes the pin to fuse, thereby terminating operation of the motor.</p> |
