Description
Technical field
The present invention relates to a kind of permanent magnet direct current motors
Background technique
High-power DC motor is a kind of improvement to common permanent magnet direct current motor, it is a kind of iron clamp magnetic
Permanent magnet replaces shoe permanent magnet.The invention belongs to second level permanent magnet direct current motor, iron clamp magnetic permanent magnet is to common shoe permanent magnetism
For iron, iron clamp magnetic permanent magnet can be done bigger, can manufacture high-power DC motor.In common permanent direct-current electric
In motivation, permanent magnet is usually made shoe, and casing is made into cylindrical shape, and the outer circle of permanent magnet is mounted on the inner wall of casing cylinder
On, inner circle and rotor engagement, the maximum deficiency of the permanent magnet direct current motor of this structure are that the installation of rotor is attracted in magnetic force
Lower progress is affected by magnetic forces the installation of rotor, and disassembly is very inconvenient, can not install to high-power DC motor,
Therefore this permanent magnet direct current motor power all very littles.
The content of present invention
The technical problem to be solved in the present invention is to provide a kind of high-power DC motor, and it is electronic to belong to Permanent magnet DC
Machine field.Its technical contribution is: the frame of stator is that a both ends are ring shape, and intermediate two sides are the rectangular of arc panel
Shape.One semicircle iron plate, a semicircle permanent magnet, a semicircle soft iron magnetic pole form one group of iron clamp magnetic permanent magnet, altogether
Two groups, it is separately mounted to the upper and lower of two middle side part of frame arc panel.It, can be with iron clamp magnetic permanent magnet for common permanent magnet
Iron clamp magnetic permanent magnet is manufactured bigger, and high-power DC motor can be manufactured.
In order to solve the above-mentioned technical problem, permanent magnet direct current motor of the present invention is made of stator and rotor.Form stator
Component include: frame, semicircle iron plate, semicircle permanent magnet, semicircle soft iron magnetic pole, magnetic conductive board, end cap, brush assembly,
Bearing, pedestal etc..Rotor uses common two pole DC motor rotor.
The frame is made of alloy aluminum, and ring shape is made in frame both ends, and intermediate two sides are arc panel, a semicircle
Iron plate, a semicircle permanent magnet, a semicircle soft iron magnetic pole form one group of iron clamp magnetic permanent magnet, totally two groups, install respectively
Above and below in the middle part of frame arc panel, constitute stator exterior round, internal soft iron magnetic pole is magnetic pole after permanent magnet magnetizes, and
Rotor engagement.Rectangle arc panel is made with iron plate in magnetic conductive board, and totally two are separately mounted to outside two side frames and two semicircles
Between shape iron plate.The rotor uses common two pole DC motor rotor, and armature spindle passes through bearings at both ends, is mounted on cast iron
In the bearing block of manufactured two end cap internal diameters, two end caps are separately mounted in the circle at frame both ends, two brush assemblies
It is separately mounted to the end cap inside that armature spindle has one, commutator.One special installation, the replacer for dismantling iron clamp magnetic permanent magnet
It is made of the identical DC electromagnet of two shapes, working method is: with the identical DC electromagnet in two the two poles of the earth and iron clamp
The two sides of the semicircle iron plate at magnetic permanent magnet the two poles of the earth and semicircle soft iron magnetic pole are attracting, semicircle iron plate and semicircle soft iron magnetic pole
Front and the other side with regard to several exhale no magnetic force, installing in this way, dismantling iron clamp magnetic permanent magnet is the condition in no magnetic force
Lower progress, it is very convenient, biggish iron clamp magnetic permanent magnet can be dismounted, powerful permanent magnet direct current motor can be manufactured.
Present invention is further described in detail with embodiment with reference to the accompanying drawings of the specification.
