THE FRAME CONSTRUCTION OF WATER COOLED MOTOR

摘要

A frame structure of a water cooling motor is provided to reduce failure rate of a cast molding and to improve mechanical strength by increasing cooling function by cooling water circulation. A frame structure of a water cooling motor increasing a cooling function comprises the followings: a motor including a stator(11) and rotor(12) positioned between a front bracket(16) and a rear bracket(18); a inside body(20) including an exterior space part(22) connected to a spiral shape, and installed between brackets in order to circle around an exterior of stator; an outside body(30) installed between brackets in order to circle around an exterior of the inside body; and an airtight unit(40) including a packing(42) and an O-ring(45) among bracket and the outside body.
