Its technique contribution lies in: the V -arrangement is made on the outer upper portion of casing of stator, and the V -arrangement is made down to outer lower part, and both sides and both ends are plane shapes. The permanent magnet of iron clamp magnetic structure is installed in the upper portion and the lower part of casing outside both sides, and the casing is inside to be made circularly, on the circle wall, adopts magnetic force direction technique including two arc soft iron magnetic poles installations, and very big installation, the dismantlement that has made things convenient for iron clamp magnetic structure permanent magnet can produce powerful permanent magnetism direct current dipolar motor.
Description
Technical field
The utility model relates to a kind of direct current machine, particularly a kind of permanent magnet DC motor.
Background technology
Permanent magnet DC motor improves the one of direct current machine, and it is a kind of direct current machine replacing electromagnetism main pole using permanent magnet as main pole.The utility model belongs to dipolar permanent direct current machine.Permanent magnet DC motor, can saves energy for direct current machine.In the permanent magnet DC motor of prior art, a watt shape normally made by permanent magnet, casing makes cylindrical shape, the cylindrical of permanent magnet is installed on the inwall of casing cylinder, inner circle and rotor engagement, the maximum deficiency of the permanent magnet DC motor of this structure is the installation of rotor is carry out under magnetic attraction, by magnetic influence, have no idea to realize the installation of High power PM DC motor, therefore this permanent direct-current electric acc power is all very little.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of High power PM DC motor, belongs to direct current machine field.Its technical contribution is: V-arrangement is made on the outer top of casing of stator, and inverted V-shaped is made in outer bottom, and both sides and two ends are all planar shaped.The permanent magnet of iron clamp magnetic structure is arranged on the upper and lower of both sides outside casing, casing internal makes circle, two arc soft iron magnetic poles are arranged on inner round wall, adopt magnetic force guiding technique, greatly facilitate the installation of iron clamp magnetic structure permanent magnet, dismounting, powerful DC two-pole machine can be produced.
In order to solve the problems of the technologies described above, the utility model permanent magnet DC motor is made up of stators and rotators.The parts of composition stator comprise: casing, cushion block, permanent magnet, iron plate, soft iron magnetic pole, casing pad, end cap, brush, magnetic pole connecting plate etc., rotor adopts the rotor that common secondary direct current machine is identical.Described casing soft iron makes arc, outer " V " font, planar shaped is made in two ends and both sides, manufacture two pieces, cushion block non-magnet material makes cuboid, does two pieces, is arranged on the both sides of two pieces of casing inner arcs with two pieces of cushion blocks respectively, casing is formed interior circular, outer top is " V " font, and bottom is for falling " V " font, and two ends and both sides are the shape of planar shaped.Cuboid made by permanent magnet, one piece of iron plate is respectively filled at the two poles of the earth of cuboid permanent magnet, composition iron clamp magnetic structure, totally four pieces, to be arranged on respectively above the both sides outside casing and below, two arc soft iron magnetic poles respectively symmetry are arranged on inner round wall, soft iron magnetic pole is main pole after permanent magnet magnetization, and casing pad non-magnet material is made into the shape of inner circle foreign side, totally two, be separately fixed at the two ends of casing, coordinate with end cap, end cap is made of cast iron outer circular shape and coordinates with casing pad, and inner circle installs bearing, bearing for installing rotor, totally two.Brush is arranged on the end cap of rotor commutator one end, magnetic pole connects iron plate, rectangle totally two pieces is made by soft iron, be arranged on the two poles of the earth of iron clamp magnetic structure respectively, magnetic force guider is made up of two flute profile DC electromagnet, be the auxiliary equipment of the direct motor of permanent magnetism, be mainly used in the installation of permanent magnet iron clamp magnetic structure, dismounting.The two poles of the earth identical for flute profile DC electromagnet A can be docked with the both sides of permanent magnet the two poles of the earth iron plate 4 respectively when implementing magnetic force guiding, making current, allow electromagnet A and permanent magnet iron plate both sides attracting, the front of such permanent magnet the two poles of the earth iron plate does not just almost have magnetic force, install in this way, to dismantle permanent magnet very convenient, install, dismantle and carry out under without magnetic force condition, powerful permanent magnet DC motor can be manufactured.
Below in conjunction with Figure of description and embodiment, the utility model is described in further detail.
