Title: FIELD DISCHARGE RESISTOR UNIT AND SYNCHRONOUS MOTOR INCLUDING SAME
Abstract:
The purpose of the present invention is to provide a field discharge resistor unit, which has an improved thermal stability and has an easily adjustable resistance value and heat capacity, and a synchronous motor including the same. A field discharge resistor unit according to an embodiment of the present invention is a device coupled to a rotary shaft of a synchronous motor and connected to a coil wound on a rotor of the synchronous motor, to reduce a magnitude of an electric current flowing through the coil wound on the rotor, and comprises: a hub which has a receiving space therein and is coupled to the rotary shaft of the synchronous motor so that a rotary movement of the hub matches that of the shaft; and at least one conductor disk which is received in the receiving space of the hub and may function as a resistor when an electric current flows therethrough.
