Abstract
The utility model relates to a permanent magnetic motor. Through permanent magnetic massive rotors loaded with stable elements the motor generates larger unit output power. The utility model adopts stators without iron cores. The method of the wire connection and the wire dropping is the same as the ordinary motor. The rotor is made on a non-magnetic frame where a permanent magnetic block is loaded. When the motor is used as an alternating current generator, the standard rotor magnetic block adopted can generate larger unit output power. The direct current excitation is not required, and as well as a sliding ring and an electric brush are not required. The motor has the characteristic of the helpful voltage stabilization when the vibration is reduced and the power supply is fed. As an electric motor, the motor which is the same as the electric motor of the current converter and the position sensor can be operated. According to the mode, the power and the efficiency of the working are farthest in excess of the induction motor. The efficiency of the electric motor whose rated power is a few KW reaches more than 90%. The range of the speed variation is very wide. The utility model can be operated and started under very low speed.
Description
The utility model relates to a kind of magneto, and it is the improvement of existing motor.This motor produces bigger unit capacity by the block rotor of the permanent magnetism that stable element is housed.It can be used as generator or motor, is more suitable for doing stepless speed-regulating motor.
Existing mag-dynamo can not be made alternating current motor and use.DC generator needs excitatory, complex structure, and volume is big, and carbon brush is easy to wear, the manufacturing process complexity, efficient is low, uses inconvenient maintenance.
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, designs a kind ofly both can make generator, can make the magneto of alternating current motor again.
When as alternating current generator, this motor adopts the standard rotor magnetic patch can produce bigger unit capacity, and does not want continuous current excitation, slip ring and brush.This motor has the advantages that to help voltage stabilizing when making vibration weakening and feed.It can turn round as the motor of converter and position transducer as motor, and power factor of working in such a way and efficiency far surpass induction motor, so rated power is that its efficient of motor of several kilowatts is up to 90%.The velocity variations scope is very wide, can smooth operation and starting automatically under extremely low speed.
Narrate content of the present utility model in conjunction with the accompanying drawings:
Permanent magnet motor structure described in the utility model is shown in figure one, two.
The utility model magneto adopts no iron core formula stator, its wiring, inserting method the same with common squirrel cage motor (shown in figure three), and figure three is the stator coil plastic frame, totally 24 grooves all around, figure four is a mode of connection.Span 1-6.Rotor is by packing permanent magnets on back-shaped and make.Housing can be made with magnetic material or nonmagnetic substance.
This magneto is made up of stator, rotor and housing three parts, is characterized in: (1) stator is by stator winding 19, and winding frame 18 retainer rings 26 are formed, and is fixed together by bolt 22 and shell end cover 15 bearing (ball) covers 21.(2) rotor is by armature spindle 1, rotor thigh 2, outer permanent magnets 3, interior permanent magnets 4, compositions such as outer steel sleeve 6, snap ring 8 nuts 9, chapelet 5, backing ring 7.Outer permanent magnets 3 dresses are solid to be entangled by outer steel sleeve 6 on the foreign steamer of rotor thigh 2, and permanent magnets 3 is gradient to the inside to match with hole frame gradient rotor thigh foreign steamer, it can not inwardly be extruded, permanent magnets 3 outsides are entangled by outer steel sleeve 6, and the one, fixed permanent magnets 3, two, can antimagneticly let out outside the venue.Interior permanent magnets four dresses are solid, and the inside is propped up by chapelet 5 on the interior wheel of rotor thigh 2, and the left side withstands 5 by backing ring 7.Snap ring 8 blocks backing ring 7.Around the interior permanent magnets 4 frame outwards gradient with rotor thigh 2 in wheel hole frame gradients matches, when making its rotation in permanent magnets not reason rotate and throw away.Rotor thigh 2 and armature spindle 1 be by square (the X place of armature spindle 1) packaged closing, and tighten fixing by nut 9, packing ring 10.Armature spindle 1 links by bearing 11 and housing.The shaft extension end is taken turns 12 conducted power by power conduction.(3) stator winding is fixed on the housing, places between the inside and outside permanent magnets, and suitable gap is arranged.Match with the equilateral polygon frame between winding frame 19 and the retainer ring 26, shown in figure three, winding frame 18 endoporus are equilateral octagon.Housing, end cap, bearing cap, armature spindle adopt non magnetic material manufacturing better.Terminal board 17 connects the motor lead-out wire, outlet lid 16 protection terminal boards.
Show as figure two, four pairs of inside and outside permanent magnets, totally eight, equidistantly place the inside and outside of rotor thigh 2 to take turns respectively, inside and outside magnetic patch two bipolarities are solid on the interior foreign steamer of rotor thigh 2 to dressing on the contrary, and two pairs of adjacent magnetic pole and magnetic field directions are opposite.In the middle of relative two magnetic patch is stator winding 19.Drive inside and outside permanent magnets rotation when armature spindle 1 rotates, stator conductor cuts the magnetic field between two relative permanent magnets, makes and produces alternating current in the stator conductor.Perhaps feed the rotating magnetic field that alternating current produced in the stator winding and repel permanent magnets magnetic field, permanent magnets is rotated, in generation,, moving armature spindle rotated.Change stator winding voltage or supply frequency and can change rotating speed.That stator can be is single-phase, two-phase or three phase windings.
The effect of outer steel sleeve 6 is to prevent that magnetic field from leaking and fix outer permanent magnets.Outer steel sleeve left side invagination hem width degree is narrower than outer permanent magnets thickness slightly, to fasten rotor thigh foreign steamer left side small end face.Outer steel sleeve 6 right edges inwardly flanging are buckled in the rotor thigh outer channel.Magnetic field, the outer permanent magnets outside makes its do not leak (shown in figure one, two) by steel bushing 6 closures.
Rotor thigh 2 right-hand member high spots are opened four oblong aperture between two magnetic poles, play the ventilation effect.
Having designed dustproof felt collar 24 on the bearing (ball) cover 14 and on the housing 13 and between the rotating shaft, to prevent that the dirt ash from entering in the bearing and greasy dirt enters in the rotor.Shaft extension end bearing end cap 14 is fixed by bolt 23 and housing.25 is support.20 is lead-out wire.
The utility model parts, as housing 13, terminal cap 14,15,21, rotor thigh 2, chapelet 5, backing ring 7, locking nut 9, drum stand 18 retainer rings 26, armature spindle 1 grade can adopt injection molding.At least two pairs of magnetic pole logarithms can become even number formula ground to increase according to designing requirement the most for a long time.
Compare with prior art, the utlity model has assembling easily, cost is low.Volume is small and light, does not use silicon steel sheet can save a large amount of non-ferrous metals.Electric machine speed regulation is convenient, and speed-regulating range width is stable, can smooth operation and starting automatically under extremely low speed.
