ABSTRACT:
The present invention refers to an electronic switching electric motor.
In particular, the present invention refers to, without in any way losing any of its generality, an electronic switching electric motor which may be used to advantage for activating ventilation devices to be installed in refrigerators, and comprises a stator, and a rotor which is rotatably coupled to the stator itself, and an electronic device for supplying and controlling the electric motor itself.
Normally, in electronic switching electric motors of well-known types, the above-mentioned stator comprises a determined number of stator teeth, a determined number of windings realised around the teeth themselves, and an assembly element of the teeth themselves realised in insulating plastic material to insulate the windings one form the other and from the stator teeth themselves.
With regard to well-known types of electronic switching electric motors currently in use for activating ventilation devices, electric motors of the kind mentioned above present a high level of operating efficiency and a low level of consumption, and, taking into consideration that the demand for electric motors for activating ventilation devices is in the order of hundreds of thousands of units per year, the use of electronic switching electric motors for these kind of applications means that considerable savings in financial terms can be made.
It should be stated, however, that the electronic switching electric motors currently in use still have a relatively complex structure, to the extent that the achievement of the above-mentioned savings in financial terms is somewhat compromised.
The aim of the present invention is to realise an electronic switching electric motor which can be used for the activation of ventilation devices in refrigerators, which is economically viable and simple to produce.
According to the present invention, an electronic switching electric motor is to be realised comprising a rotor, and a stator defined by a number of stator teeth and by an assembly element of the stator teeth themselves; the electric motor being characterised by the fact that the said assembly element comprises two support seats for the rotor, at least a first seat of the said two seats being realised with the assembly element itself.
