Abstract

The utility model relates to a single-phase two-pole motor. The main coil (8) of a two-pole single-phase concentric winding has two taps (3) and (6); the positions of the taps are determined by the two-way 220V and one-way 380V turn number difference of each pole of phase winding. Winding heads (1), (4), winding tails (2), (5) and the taps (3), (6) are respectively connected to a converting switch; a vice-winding (9) is connected in series with a centrifugal switch (7) and is connected to two thread ends (1), (4) of the two-pole coil. The utility model can work under two sort of voltage just being required to wrench the converting switch by utilizing one motor, dispensing with accessory elements such as transformers, etc. The alternating-current 220 v, 380 v two-purpose motor facilitates users and saves expenditure for the users.

Description

Alternating-current 220V, 380V two-purpose motor

The utility model relates to a kind of single-phase 2 utmost point motors, it can exchange single-phase 220 volts with 380 volts of two kinds of power supplys of two-phase on use.

At present, known monophase machine can only use on 220 volts of power supplys, does not so just have the user in the area of 220 volts of power supplys to cause difficulty to having only 380 volts of power supplys of three-phase, and particularly this situation in rural area is very general.

The purpose of this utility model provides a kind of motor, and it can not only be worked on 220 volts of power supplys, and can work on 380 volts of power supplys.

The utility model is achieved in that in single-phase 2 utmost point motor windings, utilize the relation of the winding voltage and the number of turn, arranged two utmost points that can bear 220 volts of voltages separately to organize mutually, head (1) (4) that lead is arranged in each utmost point is organized mutually, the tap (3) (6) of tail (2) (5) and winding 190 Fu Dianyachu, utilize change over switch to change the mode of connection of winding, thereby reach the purpose of dual-use.

At 2 extremely single-phase concentric winding main coils (8) two taps (3) and (6) are arranged, its position is organized mutually by every utmost point that the number of turn difference of 220 volts of two-way and a tunnel 380 volt determines, winding head (1) (4), tail (2) (5) and tap (3) (6) are connected on respectively on the change over switch, and auxiliary winding (9) series connection centrifugal switch (7) is connected in two the end of a thread (1) (4) of 2 polar curve circles.

Adopt 220 volts of interchanges of the present utility model, 380 volts of dual-purpose motors, can utilize a motor only need move change over switch and just can under two kinds of voltages, work, do not need the attached original paper of transformer and so on, greatly facilitate the user, saved spending to the user.

Following comparative examples accompanying drawing is further described the utility model:

Fig. 1 is the expanded view of single-phase 2 utmost points, 24 groove concentric type winding electric machines, and solid line is a main winding among the figure, and dotted line is an auxiliary winding;

Fig. 2 is the connecting line schematic diagram;

Fig. 3 is the method for attachment of change over switch when 220 volts of voltage;

Fig. 4 is the method for attachment of change over switch when 380 volts of voltage.

(1) (2) are (8) head and tails that level is organized mutually of main winding among the figure, (4) be the head and tail that another grade of main winding (8) organized mutually with (5), (3) be (8) two taps that level is organized mutually of main winding with (6), (7) are the centrifugal switches of series connection auxiliary winding (9).

Fig. 1 is single-phase 2 utmost points, 24 groove concentric type winding electric machines, it is 220 volts of two-way, from small coil to big coil winding, in small coil, leave tap (3) and (6), the position of tap is to determine by the difference that 220 volts of two-way and one tunnel 380 volt of every utmost point are organized the number of turn mutually, the diameter of winding conducting wire is to determine that by one tunnel 380 volt of required diameter of wire copper factor allows.Auxiliary winding only plays priming because by centrifugal switch (7), and coiling according to a conventional method suitably increases the number of turn, if auxiliary winding is the main winding the pressed method coiling of capacitor operating.Behind the intact lead of embedding head (1) (4), tail (2) (5) and the tap (3) (6) of winding are received and change over switch number accordingly on the contact by number.Then change over switch is connected into the form of Fig. 3.Contact (1) and (5) are connected, again contact (2) and (4) are connected.At this moment power supply enters motor by two-way: one is entered by contact (1), and (2) go out from the contact; (5) enter from the contact that (4) go out from the contact on another road.The number of turn of every like this road series connection just is being fit to 220 volts of voltages.Again change over switch is connected into the form of Fig. 4.Contact (1) and (5) and (2) and (4) are disconnected, the contact of tapping (3) and (6) are connected.Power supply enters motor by one the tunnel, and (1) enters into contact (3) from the contact, arrives contact (6) again, and (4) go out from the contact.Power supply enters motor by one the tunnel, and (1) enters into contact (3) from the contact, arrives contact (6) again, and (4) go out from the contact.Got rid of the part number of turn of concentric type winding small coil like this, the number of turn that circuit is connected just in time meets 380 volts of voltages.

Claims

1, a kind of dual-purpose interchange micromachine is by stator, rotor and switch are formed, of the present utility model being characterised in that: two taps (3) and (6) are arranged at 2 extremely single-phase concentric winding main coils (8), its position is organized mutually by every utmost point that the number of turn difference of 220 volts of two-way and a tunnel 380 volt determines, winding head (1) (4), tail (2) (5) and tap (3) (6) are connected on respectively on the change over switch, and auxiliary winding (9) series connection centrifugal switch (7) is connected in two the end of a thread (1) (4) of 2 polar curve circles.
