Abstract
A rotary drive assembly of an electric nail gun, comprising a support seat configured on a gun frame, an inner-rotor brushless DC motor and a flywheel configured inside the support seat in a coaxial manner. Along an assembly axial direction, the support seat is formed with a motor housing chamber to house the brushless DC motor and a flywheel housing chamber to house the flywheel, the two chambers being separated from each other. The motor housing chamber is formed with an axial port for assembly and heat dissipation of the brushless DC motor. The flywheel housing chamber is formed with a radial port to expose part of the flywheel outside the support seat. The axial port is perpendicular to the radial port. The invention can simplify the structure of the rotary drive assembly and facilitate its assembly and heat dissipation.
