<p>Disclosed is a motor connecting structure of an electric water pump. According to an embodiment of the present invention, the motor connecting structure of the electric water pump comprises an impeller case which has an inlet and an outlet for introducing and discharging cooling water by rotation of an impeller; a motor case coupled to a lower part of the impeller case; a fixing shaft which has a lower end fixed to a central lower part of the motor case and an upper end coupled with the impeller to be rotated; a stator which has a permanent magnet inserted thereinto and is pressed into the fixing shaft; a tube type magnet which is coupled with the impeller and inserted between the motor case and the stator; and a driver case which has a PCB substrate for controlling a motor installed therein and is attached to the lower part of the motor case. An electric wire of the stator is connected to the PCB substrate by a coupling force between the motor case and the driver case.</p> |
