The structure of the utility model is composed of the main windings L< 1 >, L< 2 >, L< 3 >, L< 4 > of a motor, a secondary winding L< 5 >, a starting capacitor C, a centrifugal switch K< 2 >. and a transfer switch K< 1 >. The secondary winding L< 5 >, the starting capacitor C and the centrifugal switch K are connected with a single-phase source in series. The main windings L< 1 >, L< 2 >, L< 3 >, L< 4 > of the motor are connected with the respective contact switches of the transfer switch K< 1 >. The double-voltage single-phase capacitive starting motor has the advantages of reasonable design, simple structure, easy manufacture, large output power, convenient operation, one machine with multifunction, etc. The utility model can be used on various agricultural implements, household appliances and electromechanical devices.
Description
The utility model relates to a kind of power-equipment, specifically a kind of two voltage single phase condenser motors that use single-phase 220V or 380V power supply.
The employed voltage of general purpose motor mostly is 220V or 380V at present, 380V also cries the electricity consumption of three-phase power, the general of 220V is electric consumption on lighting, thereby the kind of motor is also divided threephase asynchronous that uses 380V voltage and the single-phase capacitance starting asynchronous motor that uses 220V.A kind of in general motor can only use a kind of voltage, otherwise motor is damaged.Along with the increase of the varities of industrial products and the variation of household electrical appliance, it is more and more general that single-phase motor and threephase motor use in various electronic products and household electrical appliance, such as air-conditioning, low power general use 220V single-phase electricity is just passable, singly be the voltage that then will use 380V that the motor of big refrigerating capacity cabinet air-conditioner has, the motor that uses on the small-sized for another example wood-turning machine mostly is the 220V single phase condenser motor, there is the 220V power supply job site that has, what have then has a 380V power supply, as does not have suitable power supply engineering then can't carry out.In order to solve the problem that motor must use single power supply, there are a lot of people to design the used 220V of various structures or the motor of 380V voltage, though can on equipment, use, in use still have complex structure, fluctuation of service, starting current is excessive, outputting power is not enough problem with regard to the above-mentioned improved motor that uses two kinds of voltages at present.
The purpose of this utility model provides that a kind of simple in structure, working stability, power output are big, two voltage single phase condenser motors of long service life.
The purpose of this utility model realizes in the following manner, in motor, establish capacitor start auxiliary winding and main winding, in the main winding each winding just end and end respectively with change over switch in two groups of switches join, the mutual conversion of two groups of switches by change over switch realizes the connection combination of each winding, motor is adapted to work under different voltages.
Accompanying drawing is the main winding and auxiliary winding of two voltage single phase condenser motors and the syndeton schematic diagram of change over switch.
With reference to the technology of Figure of description to of the present utility model pair of voltage single phase capacitive starting Structure, feature explain below doing.

Embodiment:
Of the present utility model pair of its processing and fabricating of voltage single phase condenser motor is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Major-minor winding in the motor technique for coiling of single-phase capacitance starting asynchronous motor routinely carries out, and change over switch can be selected the universal seclector of commercially available LW5-15/4 model for use.Use identically, rotate the selection conversion that change over switch just can be finished voltage with other common electric machines.
Of the present utility model pair of voltage single phase condenser motor compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, big, easy to use, a tractor serves several purposes of power output, can on various agricultural machinery and implement, household electrical appliance and electromechanical equipment, use thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
