Description
The present invention relates to a kind of wire wound asynchronous motor, belong to machine field.
The three-phase winding-type asynchronous motor of current domestic and international use, stator winding are " three-phases ", and the rotor winding is " three-phase ".The starting resistance of adapted, relay, contactor etc. (general name " starting equipment " also claims " control appliance ") must be used " three covers ".The capacity of motor is bigger, the Device element that needs the more, thereby cost height, the occupation space volume is big, installs and maintenance when all taking a lot of work very much, and is for many years, like this always." SCR cascade speed control " on probation person was arranged in recent years both at home and abroad, though starting and control equipment has improvement, the internal structure of motor own does not change, with Device element quantity still a lot, the cost cost is higher, installs and keeps in repair when still taking a lot of work very much, and operation owes reliable.
In disclosed " Shandong Mineral College " the 8th phase of nineteen eighty-two May 15 nineteen eighty-two (Shandong Mineral College institute periodical editing cubicle is compiled), disclose stator three-phase rotor two-phase wire wound asynchronous motor and can reduce starting equipment, but still needed to adopt three slip rings and two cover starting equipments.
The objective of the invention is further to reduce starting and control equipment, only need adopt two slip rings and a cover starting and control equipment, can improve running reliability of motor thus, and be convenient to safeguard and maintenance.
The present invention adopts the wire wound asynchronous motor of three-phase stator winding rotor two phase windings, three-phase stator winding is same as the prior art, two groups of windings of rotor are mutually 90 electrical degrees and place, after rotor two phase windings are parallel with one another, two terminals of being drawn link with two slip rings respectively, link by a brush and a cover starting equipment.
The present invention will be described in detail below in conjunction with accompanying drawing.

Fig. 5 (b) is used a kind of rotor two-phase coupling method and the starting and control equipment of the present invention.
In the wire wound asynchronous motor of existing three-phase stator winding rotor two phase windings, the coupling method of rotor two phase windings and with the connecting normally like this of starting and control equipment:
To large and medium-sized and often back and forth start, the person of stopping, " slip ring " is advisable with three, " starting and control equipment " usefulness " two overlap " is referring to accompanying drawing 4.Wherein a, b, c represent that motor stator three phase windings are connected in three terminals of power supply.A ', B

Fig. 5 (a) shows usefulness " four resistance ", the connection of three grades of startings.Adorn with three contactors.Wherein the 1st, the 2nd contactor all is a contact, and the 3rd contactor is two contacts.
This shows: existing stator three-phase rotor two-phase winding type asynchronous motor still need use three slip rings and two cover starting and control equipments.
The present invention is achieved in that
To medium and small capacity person and stable load (for example dress is used for water pump, blower fan, air compressor)." slip ring " can be with two, and starting and control equipment is used " cover ".As accompanying drawing 5(b) shown in, need only be with three " starting resistances ", three contactors, each need only a joint.
Three-phase stator winding of the present invention can adopt
Or
Connect by (accompanying drawing 1), also can adopt Y shape or △ shape to connect separately.
Rotor " two-phase " winding is mutually 90 degree electric angles.The coil of every phase is a multi-channel parallel, also can be one tunnel series connection, and the layout of rotor winding is seen accompanying drawing 2 and 3.
Fig. 2 shows is that the coil of rotor 48 grooves, 4 utmost points, every phase winding is one tunnel series connection, also can be arranged as 2 tunnel parallel connections.
What Fig. 3 showed is rotor 72 grooves, 6 utmost points, and the coil of every phase winding is one tunnel series connection, also can be arranged as 3 tunnel parallel connections.
The series line number of turn of the every phase of rotor winding is more, is 1.5～2 times of JR series.Just: motor of the present invention, rotor voltage is higher, and rotor current is less.
Motor of the present invention, the series line number of turn of the every phase winding of rotor is for 2 times of the number of wire turns that whenever is in series of JR serial motors rotor are advisable.Concrete measure is:
(1) rotor adopts more groove number, is about 1.5 times of JR series, and the size of rotor is less, is about 2/3 times of JR series.
(2) the rotor conductor number is more, is about 2～3 times of general JR series, correspondingly the sectional area of every groove lead is reduced, and just the sectional area of rotor wire is 1/2～1/3 of a JR series.
(3) it is better that the coil of the every phase winding of rotor adopts multi-channel parallel.
(4) " slip ring " on the rotor axis of electric (comprising carbon brush and annex thereof) used " two ".
The key dimension of motor can be identical with general conventional JR series person.
According to relational expression p=CD
2In the Ln(formula: p is a power, and C is a constant, and n is a rotating speed, and D is a diameter, and L is a core length).Big capacity person can adopt bigger diameter D, short core length L.
The magnetic loading B of motor
δ(air gap flux density) and electric loading A can be identical with general JR serial motors.
The present invention has following advantage:
1, motor of the present invention has been simplified control appliance.
2, industrialness facts have proved, motor of the present invention is reliable, is convenient to maintenance.
