Electrical drive motor, in particular for water pumps in the field of aquaria
First Claim
1. A sealed electrical drive motor, in particular for water pumps in the field of aquaria, the motor comprising a motor shaft, a universally liquid-proof and gas-proof sealed housing including a thin walled diaphragm at one end thereof, a permanent-magnetic coupling including a magnetic member on said motor shaft which acts through said thin-walled diaphragm, an end of said motor housing which is to face a water pump being defined by said thin-walled diaphragm, said thin-walled diaphragm having a planar outer surface which is engageable with a likewise planar, sealed diaphragm surface of a pump casing, and where in vicinity of said thin-walled diaphragm there are provided securing means for connecting said motor housing to a pump casing.

Abstract
There is disclosed an electrical drive motor, in particular for the water pumps in the field of aquaria, wherein the housing is universally sealed liquid- and gas-proof and wherein a permanent-magnetic coupling is located on the motor shaft acting through the sealed housing wall. In order to render this drive motor independent so that it may be used for various units, is able to be connected thereto with no problems and in addition thereto is reliable, the side of the motor housing directed toward the water pump is defined as a thin-walled diaphragm with a planar outer surface which is engagable with a likewise planar sealed diaphragm surface of the pump casing, in the area of the diaphragm securing means being provided for connecting the motor housing to the pump casing. Such a motor may be used with no problems in the field of aquaria and may even be used submerged in water.
