Abstract

The invention relates to a multi-magnet direct current motor which can be used as an electric motor or an electric generator. In the invention, a rotor comprises a plurality of magnet disks, a stator comprises a plurality of coil plates, and a commutator is a novel one.

Description

Multi-magnet direct current motor

Technical field:

The present invention is a kind of DC motor, also can make alternating current generator and use.

Background technology:

DC motor coil commonly used is on rotor.Structure makes coiling difficult.

Summary of the invention:

The present technique coil is on stator, and coiling easily.Can use high-tension electricity.Can a coil board with two magnetite plate holders, be contained in the electric wheel and use, can organize and usefulness more, enlarge power.

Two blocks of round plastic plates that diameter is identical are arranged, thick identical, opened eight holes on every, open 16 holes altogether for two.16 holes are equally big, and they equate to the distance in the plastic plate center of circle.Each hole is all very short to the distance of plastic plate outer.Each hole equates all that with distance between the adjacent hole plastics partition wall between hole and the hole is very thin, installs a magnetite in each hole.On same of same block of plate, magnetic pole always shows N-S-N-S-N-S-N-S.By the center of circle of two plastic plates, put on axle, make two plastic plates parallel to each other, and perpendicular to axle, the thickness of the plastic plate in two plastic plate intervals add the thickness of 0.4mm.Plastic plate and axle are solidly installed, and eight magnetites on plastic plate face eight blocks of magnetites on another piece plastic plate, and, two relative magnetite polarity differences, always N to S or S to N.Two setting-ins the plastic plate of magnetite be exactly rotor.

Other has three plastic plates, and every the same thick with a rotor plastic plate.Three lay respectively at two rotor plastic plate both sides and centre, be packed on the motor cabinet, and the 0.2mm gap arranged between the rotor plastic plate. respectively opened eight holes on these three plastic plates, totally 24 holes, if the size in each hole is the same with the hole of setting-in magnetite big. in each hole all setting-in an annular enameled wire loop. the magnetite in the rotor is ferromagnetic materials such as neodymium iron boron, then just do not adorn magnetic conductive iron in the middle of the enameled wire loop, if the magnetite in the rotor is a non-ferromagnetic material, then will load onto iron core in the middle of the enameled wire loop. these three plastic plates are packed on the electric machine stand, as stator.Direction along armature spindle, allow eight holes of first block of plate of stator face eight holes of second block of plate, also face eight holes of the 3rd block of plate. say the winding method of annular enameled wire loop now: since three blocks of plates certain three over against coil of coil of money circle clockwise direction around.On first block of plate first coil in the direction of the clock around, second coil by counterclockwise around, the 3rd is suitable, the 4th contrary ...On second block of plate, first coil in the direction of the clock around, second coil by counterclockwise around, the 3rd is suitable, the 4th contrary ...On the 3rd block of plate, first coil in the direction of the clock around, second coil by counterclockwise around, the 3rd is suitable, the 4th contrary ...The coil of three plates can and be connected to commutator, also can connect and receive commutator.To should be mentioned that one of method of coiling " two-wire simultaneously around " especially, use eight coils on first block of plate of two wire-wounds of same specification exactly, after intact, do not block, continuation is around second block of plate, around the 3rd block of plate, the back is divided into A the end of a thread to two lines and A line tail, B the end of a thread and B line tail are standby around finishing again.Commutator is made of three slip rings and three carbon brush, and middle slip ring is made up of eight copper sheets, the commutation eight times of turning around.The method for making of commutator: cut diameter 20mm, two sections of the thin-wall copper pipes of long 20mm are vertically sawed with hacksaw again, are not transversal, and being half of 1 section copper pipe that 10mm is long equably is divided into eight parts, 1,3,5,7 part has been removed do not wanted, another section copper pipe also processing like this.Each four parts of surplus transpostion interval of two sections copper pipes are lumped together, and at this moment, two sections long altogether 30mm of copper pipe are set to them on the sticking plaster earlier, again through the seat of commutator on the armature spindle.Eight copper sheets number in order into: 1,2,3,4,5,6,7,8, wherein 1,3,5,7 and left side copper pipe be in one, 2,4,6,8 and the right copper pipe are in one.Left side copper pipe connects A line the end of a thread by carbon brush, and the right copper pipe connects B line line tail by carbon brush, and middle that carbon brush was brushed eight copper sheets successively, and it connects positive source, successively electricity is given A the end of a thread, B line tail, A the end of a thread, B line tail ...And A line line tail and B line the end of a thread lump together and connect power cathode.

The time of commutator commutation is the point of magnetite and coil alignment.Make a magnetite diameter a little bit smaller, be not embedded in over against the position, help the starting.

Claims

1. the magnetite on plastic plate of rotor faces the magnetite on another plastic plate.

2. magnetite N, the S utmost point one positive one anti-phase on a plate are evenly distributed in the periphery of rotor plectane, for actuating motor, have one or two not in positive position.

On two magnetite plectanes over against the polarity of magnetite different.

4. the coil on plastic plate of stator faces the coil on other several plastic plate.

5. the magnetite number on the coil number on stator plastic plate and the rotor plastics plectane equates.

On the rotor on the diameter of a circle at magnetite place and the stator diameter of a circle at coil place identical.

7. commutator only connects positive pole or only connects negative pole.
