Abstract
A kind of micro machine with variable voltage phase-shift device.The present invention includes transformer group, single-phase micro-motor, shift capacitor, wherein transformer group is made of two sets of transformers, its output voltage is supplied respectively to the main winding of single-phase micro-motor and pays winding, and shift capacitor is serially connected in the primary coil circuit for a set of transformer that supply single-phase micro-motor pays winding.Phase shift of the present invention due to dexterously supplying single-phase micro-motor realization micro machine in the primary coil of transformer shift capacitor in tandem, neither will increase the volume of capacitor, and will not improve the price of capacitor, can be widely applied to the phase shift of various single-phase capacitance micro machines.
Description
Technical field
It is especially a kind of for the extractor fan of forced-ventilated water heater, exhaust fan, fan the present invention relates to a kind of micro machine
Single-phase micro-motor in blower.
Background technique
The extractor fan of existing forced-ventilated water heater, exhaust fan, blower used in electric fan generally use the friendship of 220V
Monophase machine is flowed to drive impeller, and the primary and secondary winding of monophase machine is supplied respectively to using shift capacitor, but this structure
Its motor volume of blower is big, occupied space is more, is unfavorable for blower installing and using in water heater, exhaust fan or fan, and by
Be not belonging to the safe voltage in electrical standard in 220V, influence using security reliability, for above situation, some producers are adopted
Impeller is driven with the 6V-36V single-phase micro-motor of safety low-pressure, and a transformer need to be installed before motor at this time, it will be commonly used
220V alternating current be changed into 6V-36V alternating current for the use of 6V-36V single-phase micro-motor, but the shifting in single-phase micro-motor at this time
The capacitance of phase capacitor can be increase accordingly, and incrementss are that the multiple of transformer transformation ratio multiplies used capacitor when former 220V
Amount, the capacitor volume of this large capacity is again big, and price also your many, not only the installation of fan was made troubles, but also increased blower
Cost.
Summary of the invention
The object of the present invention is to provide one kind can holding capacitor amount it is constant, it is at low cost, small in size, easy for installation have become
Pressure claims the single phase ac micro machine of phase device.
The present invention includes single-phase micro-motor, shift capacitor, it is characterised in that further include having transformer group, the transformer group by
Two sets of transformer compositions, output voltage is supplied respectively to the main winding of single-phase micro-motor and pays winding, and shift capacitor is serially connected in
In the primary coil circuit for supplying a set of transformer that single-phase micro-motor pays winding.The present invention is due to dexterously in the first of transformer
Grade coil shift capacitor in tandem supplies the phase shift that single-phase micro-motor realizes micro machine, with alloing shift capacitor capacitance with it is existing
The capacitance of the shift capacitor of capable 220V alternating current generator is equally big, neither will increase the volume of capacitor, and will not improve capacitor
Price, can be widely applied to the phase shift of various single-phase capacitance micro machines, and install it is simple, conveniently, occupied space is few, save at
This.
Detailed description of the invention
Below in conjunction with attached drawing the basic structure and principle that the present invention will be described in detail：
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is electric schematic illustration of the invention；
Specific embodiment
As Figure 1-Figure 2, the present invention includes single-phase micro-motor 2, transformer group 4, shift capacitor 3, wherein single-phase micro- electricity
Machine 2 uses the single-phase micro-motor of 6V-36V alternating current, and transformer group 4 is made of two sets of transformers, and output voltage is supplied respectively to
The main winding 21 of single-phase micro-motor 2 and pair winding 22, and shift capacitor 3 is serially connected in supply single-phase micro-motor 2 and pays the one of winding 22
In the primary coil circuit for covering transformer, guarantee shift capacitor 3 uses in 220V exchange electrical environment in this way, is not required to increase its electricity
Capacity facilitates it to install and reduce cost, is equipped with impeller on the output main shaft of single-phase micro-motor 2.
