Abstract
Provided is an electrostatic coating apparatus capable of insulating an electric motor electrically from a member, to which an electrostatic high voltage is applied, and reducing the size and weight of the electrostatic coating apparatus. This electrostatic coating apparatus comprises a rotary atomizing head, to which high voltage is electrostatically applied, an electrostatically grounded AC servomotor, and a spindle and a fixed insulating member for insulating the AC servomotor electrically from the rotary atomizing head and a speed-increasing device to be set at the same potential as that of the former. The spindle and the fixed insulating member have insulation distance enlarging portions and of the mode, in which the creepage insulation distances from the speed-increasing device to the AC servomotor are enlarged.
