ABSTRACT:
Electromotors used as submersible motors consist of a fluid-tight housing (2), a shaft (3) mounted therein, the connecting end of which is brought out on one side in a leakproof fashion from the housing (2), a rotor (8) seated on the shaft (3), and a stator (9) fixed relative to the housing (2). In order for the electromotor to be switched over without appreciable expense from one voltage to another voltage in a very simple and reliable way, even by unskilled persons, a voltage selector switch (23) is provided in the interior of the housing (2). To actuate the voltage selector switch (23), there is provided in the region of the voltage selector switch a detachable housing part which, in the detached state, clears a housing opening through which the actuating element of the voltage selector switch (23) is accessible.
