ABSTRACT:
The space heater of the invention features an improved motor-transformer package which may be easily applied to and removed from the heater, as an integrated unit. The design and mount of this package makes it extremely easy to service and insures that in the placement and operation thereof the total package will be surrounded with an insulating flow of air, the cooling effect of which guarantees a longer and more useful operating life for the included components and related apparatus. In the preferred embodiment illustrated, the motor and transformer elements of the package are connected, in a superposed relation, to opposite sides of a mounting plate the design of which essentially dictates the required placement of the package in a heater housing.
The invention also features an improved transformer characterized by a plurality of windings which are series related in a manner to make the transformer significantly less susceptible to overheating or short circuiting than would be the case in the use of comparable conventional transformers.
