Abstract

The invention belongs to the technical field of air conditioner motors, and particularly relates to optimization of a brushless DC air conditioner motor integrated circuit board. The integrated circuit board comprises a semicircular PCB. A grounding G-galvanized connection hole and a U-galvanized connection hole, a V-galvanized connection hole and a W-galvanized connection hole which are connectedwith three windings of a motor stator are sequentially connected on the arc edge of the semicircular PCB. The semicircular PCB is applied to replace the whole circular PCB in the prior art so as to effectively save the cost. A high-integrated IC chip is connected on the semicircular PCB. The use of the high-integrated IC chip reduces the use amount of peripheral auxiliary components and has few lead wires and solder joints so as to avoid the adverse phenomenon of short circuit in the prior art, reduce the production defective rate and improve the service life, reliability and service performance. The optimization of the brushless DC air conditioner motor integrated circuit board has the advantages of using the high-integrated IC chip so that the installation amount of multiple componentsand devices is reduced, installation is enabled to be easier, the yield rate is improved by soldering and short circuit of the circuit board in use is avoided.
