Abstract

The invention relates to a multi-magnet direct current motor which can be used as an electromotor and an engine. In the multi-magnet direct current motor, a rotor comprises a plurality of magnet circular plates; a stator comprises a plurality of coil circular plates; and a reverser is a new type reverser.

Description

Multi-magnet direct current motor

Technical field:

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

Background technology:

DC motor coil commonly used is on rotor, and structure makes coiling difficult.

Summary of the invention:

The present technique coil is on stator, and its structure makes the production technologies such as coiling can mechanization production.When energising was rotated, rotated evenly at the dead point that rotor and stator do not stress.Can two coil board with three magnetite plate holders, be contained in the electric wheel and use.Also can organize and usefulness more, enlarge power.

Rotor: three blocks of round plastic plates that diameter is identical are arranged, thick identical, opened eight holes on every, opened 24 holes altogether for three, 24 holes are equally big, they to the plastic plate distance of center circle from equating.Each hole is all very short to the distance of plastic plate outer.Each hole all equates with distance between the adjacent hole.Plastics partition wall between hole and the hole is very thin.In each hole, install a magnetite.On same of same block of plate, magnetic pole always shows N-S-N-S-N-S-N-S-., put on axle now, make three plastic plates parallel to each other and, stay the thickness of a plastic plate to add the position of the thickness of 0.4mm in the middle of per two plastic plates perpendicular to axle by the center of circle of three plastic plates.Plastic plate and axle are solidly installed, and eight magnetites on plastic plate face eight magnetites on another piece plastic plate, and over against two magnetite polarity differences.Always N to S or S to N.Three setting-ins the plastic plate of magnetite be exactly rotor, rotor is contained in the bearing, during actual assembled, always adorns a rotor, refills a stator, refills a rotor, refills a stator ...

Stator: two plastic plates are arranged, every thickness, size are the same with the rotor plastic plate, two boards lays respectively between three rotor plastic plates, be packed on the motor cabinet, and the 0.2mm gap arranged between the rotor plastic plate, eight holes have respectively been opened on these two plastic plates, 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, if 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,, then will load onto iron core in the middle of the enameled wire loop if the magnetite in the rotor is a non-ferromagnetic material.In the motor that installs.Hole on this two boards be not over against, this point is important, but the numeral of the radius that punches of difference, promptly a hole on plate face two holes on another piece plate each half.Say the winding method of annular enameled wire loop now: two stator plate are done mark are divided into first block of plate and second block of plate, since first block of plate along clockwise direction coil of a coil around.First coil in the direction of the clock around, second coil by counterclockwise around, the 3rd is suitable, the 4th contrary ...Have on second block of plate a coil be positioned at than begin earlier on first block of plate around that coil fall behind some position along clockwise direction.Just it when first coil around, in the direction of the clock, first coil in the direction of the clock around, second coil by counterclockwise around ...Coil on same block of plate can be connected and be received commutator, also can and be connected to commutator, two each carbon brush of stator plate with each, but a shared slip ring will should be mentioned that one of method for winding " two-wire simultaneously around " especially, uses two each coils of wire-wound of same specification exactly, on first block of plate, two lines are divided into A the end of a thread and A line tail, and B the end of a thread and B line tail are standby, and A the end of a thread, A line tail, B the end of a thread, B line tail are also arranged on second block of plate.

Commutator is made of two slip rings and five carbon brush, it is complete ring that a slip ring is arranged, another slip ring is divided into several districts as the DC motor commutator of being on active service now, be divided into eight districts here, wherein, 1,3,5,7 districts link to each other with the complete ring in next door, and a carbon brush brushes positive electricity on the complete ring, thereby make 1,3,5,7 districts all be with positive electricity.2,4,6,8 districts are not charged, and A the end of a thread of first stator plate and B line tail have respectively divided on the slip ring of distinguishing at this by a carbon brush and slided, and A the end of a thread and B line tail wheel flow electricly, and A line tail and B the end of a thread are incorporated into together, connect power cathode.A the end of a thread of second stator plate and B line tail also are respectively to slide on the slip ring that has divided the district by a carbon brush, and A the end of a thread and B line tail wheel flow electricly, and A line tail and B the end of a thread are incorporated into together, connect power cathode.On the subregion slip ring A the end of a thread of first stator plate than A the end of a thread of second stator plate in advance 360 °/(8 * 2) angle earlier electric, and simultaneously the B line tail of first stator plate also than the B line tail of second stator plate 360 °/(8 * 2) angle elder generation dead electricity in advance.Four carbon brush should be evenly distributed in around the slip ring as far as possible.For powerful motor, just low-power level signal of sending on the commutator, touching turn-off thyristor is the motor power supply.

The time of commutator commutation is the point of magnetite and coil alignment.Should be mentioned that the commutator structure that also has other.

Claims

1. the magnetite N.S utmost point one positive anti-phase on a plate is evenly distributed in the periphery of rotor plectane.

2. the magnetite on plastic plate of rotor faces the magnetite on other plastic plate.

3. on the different magnetite plectanes over against the polarity of magnetite different.

4. the coil position on the coil on plastic plate of stator and another plastic plate diverges to 360 °/(8X2) angle.

5. the magnetite number on the coil number on stator plastic plate and the rotor plastic plate equates, and all is even number.
