ABSTRACT:
A powder coating apparatus100and a method of manufacturing a stator200are disclosed wherein the stator is set in masking caps110, 120such that axial end faces of the stator are masked by the masking caps, respectively, so as to define a first clearance in an area closer to a powder spray nozzle160and a second clearance in the other area remote from the powder spray nozzle. The first clearance closer to the powder spray nozzle160is set to have airflow resistance less than that of the second clearance remote from the powder spray nozzle for thereby permitting compressed air, delivered from a compressed air supply unit150, to be discharged through the first clearance at an increased flow rate.
