The invention avoids the damage to conducting wires when the wires are bound, achieves excellent insulation effect and improves the performance of the motor.
Description
Technical field
The invention belongs to a kind of insulation fin construction, be specifically related to a kind of insulation fin construction that is used for single-phase DC brushless motor stator winding.
Background technology
Usually, monophase machine is as the drive source of most of household electrical appliance such as compressor, washing machine, electric fan.Because brshless DC motor has replaced brush and commutator with electron rectifier, so it had both had the simple in structure, reliable, easy to maintenance of alternating current machine, possess the operational efficiency height of direct current machine, no excitation loss and good speed adjustment features again, can avoid again producing plurality of advantages such as mechanicalness noise and electromagnetic noise, be widely used in comprising the national economy every field of household electrical appliance.
Motor mainly is made of stator and rotor two parts, and stator has independently winding construction, and permanent-magnet steel is arranged in the rotor.Stator and rotor are made of the iron core that silicon steel plate stacking forms respectively.It is cylindric that stator is, and circle upwards is provided with groove in it.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the stator cylinder cavity, and certain space is arranged between stator and rotor.Stator has the winding of high strength enamelled wire coiled, and stator winding is connected with external power, outside source current by the time this electric current and the rotor permanent-magnet steel magnetic field interaction that produced, produce electromagnetic torque and drive the rotor rotation.
Stator winding is by constituting as the main winding of running winding with as the auxiliary winding that starts winding, winding is to insert an end of winding on the circle in two grooves in a plurality of grooves and insert the other end in stator in other two grooves, is wound with a plurality of windings in stator core.Therefore, be provided with the upper and lower of winding in the top and bottom of stator core, and be fixed with the top and bottom of fixed part in stator core.
That is, winding is divided into the upper end winding that is provided with on periphery unshakable in one's determination, and the lower end winding that is provided with below periphery unshakable in one's determination and be inserted between a plurality of grooves and connect the winding that is connected of upper end winding and lower end winding.
In order to prevent short circuit between the major-minor winding, burn out motor, between the major-minor winding, to separate with insulating material.What generally adopt is that main winding and auxiliary winding are insulated with insulating trip respectively.
Shown in Fig. 1～3, stator 1 is made up of a plurality of core lamination stacks, and the inside of stator 1 is formed with radial wire casing 2, is twining winding (not shown) in the inside of wire casing 2.In the inside of wire casing 2, be the center with the winding, be provided with a plurality of insulating trips 3, insulating trip 3 is between core lamination stack and winding, insulating trip 3 will play winding and the insulation between stator 1 inner rotor rotated, can not cause short circuit, make that winding is unlikely to sustain damage because of short circuit.
But the insulating trip 3 of prior art is with thickness less insulating paper, inserts aborning and breakage easily during winding process, operation is bad, insulation effect is relatively poor, causes the proof voltage of motor bad.
Summary of the invention
The present invention proposes for the problem that overcomes the prior art existence, and purpose is providing a kind of insulation fin construction of the all-in-one-piece motor stator winding that the main winding and auxiliary winding of motor stator is distinguished easily, be difficult for getting lines crossed.
Technical scheme of the present invention is: a kind of insulation fin construction of motor stator winding, described stator is made up of a plurality of core lamination stacks, is formed with radial wire casing in the inside of stator, is twining winding in the inside of wire casing, is the center with the winding, is provided with insulating trip.Insulating trip comprises outer insulation sheet and the inside insulating trip, outer insulation sheet and the inside insulating trip are linked to be an integral body, the outer insulation sheet is made up of a plurality of outer insulation monolithics, the inside insulating trip is made up of a plurality of the inside insulation monolithics, and the corresponding position of insulating trip and the inside insulating trip forms line groove hole outside.
The quantity of insulation monolithic and insulation monolithic equates.
The quantity of the wire casing in the stator equates with the quantity of line groove hole.
Outer insulation sheet and the inside insulating trip are connected to each other on top, separate in the bottom.
The breakage that when insulation fin construction of motor stator winding of the present invention has been avoided wiring lead has been caused, insulation effect is good, has improved motor properties.
