The present invention relates to an electric motor control board and, more particularly, to an electric motor control board having bus bar temperature and fire expectation monitoring functions. The electric motor control board having bus bar temperature and fire expectation monitoring functions according to an embodiment of the present invention includes: an arc monitoring module to monitor arc generated from the electric motor control board; and a temperature monitoring module to determine whether a temperature of at least one of R, S, and T shape bus bars is equal to or greater than a preset upper limit and is continuously increased, to determine whether a current of the bus bar with the temperature equal to or greater than a preset upper limit and continuously increased is continuously increased when the temperature of at least one of R, S, and T shape bus bars is equal to or greater than the preset upper limit and is continuously increased, to determine that temperature increase in the bus bar with the temperature equal to or greater than a preset upper limit and continuously increased is achieved by an excessive current when the current of the bus bar is continuously increased, and to determine the temperature increase in the bus bar with the temperature equal to or greater than a preset upper limit and continuously increased is achieved by a physical defect when the current of the bus bar is continuously not increased. |
