A submerged motor which includes a lower housing formed with a plurality of openings for passage of water, an upper housing engaged with a top of the lower housing and formed with a water outlet at a top thereof, a motor including a rotor and a solenoid enclosing the rotor and being fitted within a chamber of the upper housing, the chamber being in communication with the water outlet and has a hole communicated with the lower housing, the motor being electrically connected with a circuit board which is fitted in a recess of the upper housing, the circuit board being provided with a pair of sensors and connected with an electrical plug via a first electrical cord, an impeller being fixedly mounted on the rotor so that when the motor is turned on, the impeller will be rotated in unison with the rotor thereby forcing water of the outlet, and a cover configured to engage with the upper housing so as to close the recess thereby protecting the circuit board from damage, whereby only when the water level is above all of the two sensors will the submerged motor be turned on thereby preventing any accidents caused by overheating of the motor.
