Abstract

PURPOSE: To improve the efficiency of cooling and lubricating the interior of a motor section by providing in a front rotor chamber an auxiliary impreller mounted on a rotor shaft and communicating to the discharge side of a pump.
CONSTITUTION: An auxiliary impeller 38 mounted on a rotor shaft 24 is provided in a front rotor chamber 34 and communicates to a pump chamber 18 through a liquid path 40 and liquid passing hole 46. Thus, treated liquid discharged from the pump chamber 18 is introduced into the front rotor chamber 34 to lubricate a front bearing 30, while passing through a gap between a stator 26 and rotor 28 to cool a motor section 12 and flowing into a rear rotor chamber 36 to lubricate a rear bearing 32 so that the efficiency of cooling and lubricating the interior of the motor section 12 can be improved.
