Abstract
The invention belongs to the technique of the structural design of motors and relates to a circulating liquid cooling structure of a centrifugal pump motor. The circulating liquid cooling structure is characterized in that an internal cooling passage is composed of a liquid inlet (7), a housing front cavity (1a), a gap between a stator unit (2) and a rotor (4), a rear end cover inner cavity (5a), a liquid outlet (8), a rear bearing block inner cavity (5b) and a rotor shaft central hole (6a). The circulating liquid cooling structure has the advantages that cooling effect is improved, and the service life of the motor is prolonged.
