Abstract
A process and process apparatus for forming a protective coating on a magnetic pole of a permanent magnet motor. The process for forming a protective coating on a magnetic pole of a permanent magnet motor includes: horizontally placing a motor rotor, and controlling to perform, at positions of an inlet and an outlet operating on a vacuum bag in a current state, vacuumization and adhesive injection only on an arc section located at the bottom of the motor rotor; and driving the motor rotor to rotate by a predetermined angle after the adhesive in the arc section is initially cured so as to rotate the next arc section in which no adhesive is injected to the bottom, until all arc sections in the circumferential direction of the motor rotor are injected with the adhesive.
