Abstract

The utility model discloses a permanent-magnet direct-current motor comprising a stator and a rotor. The permanent-magnet direct-current motor is characterized in that the stator is composed of two circular magnetic poles which are adhered on a shell by permanent magnets in the way that south poles are spaced from north poles, and the rotor is composed of a plurality of armature cores distributed on an armature core connecting member in the shape of a ring and armature windings. The permanent-magnet direct-current motor can make full use of two-pole magnetic force generated when current flows through an electromagnet and the magnetic force utilization rate is 50 percent higher than that of the prior permanent-magnet direct-current motor, thereby achieving the purposes of high efficiency and energy saving.

Description

Permanent magnet DC motor

Technical field

The utility model relates to a kind of permanent magnet DC motor.

Background technology

At present, known permanent magnet DC motor structure is by being divided into two parts: stator and rotor.Stator comprises: main pole, support, commutating pole, brushgear etc.Rotor comprises: armature core, armature winding, commutator, the formations such as axle and fan, produce magnetic force in order to electricity consumption stream by armature winding and armature core, thus utilize the repulsion of magnetic force and attraction and and main pole produce displacement and convert mechanical energy to.But existing motor only has a utmost point for the utilization of magnetic force after electric current produces magnetic force, thereby wastes the magnetic force of half.

Summary of the invention

The purpose of this utility model is to provide a kind of can produce by electromagnet the efficient permanent magnet direct current machine that two utmost points of magnetic force all use by electric current.

The utility model solves the technical scheme that its technical problem adopts: a kind of permanent magnet DC motor, include stator, rotor, it is characterized in that: described stator is that two annular magnetic poles form, and annular magnetic pole is sticked on shell and forms by the order at south, interval, north by permanent magnet; Described rotor is that a plurality of by annular spread, the armature core on the armature core connector and armature winding form.

Described armature core is upper and lower two ring segments, and a wrapping post is arranged between the second ring sheet, and armature winding is wound around on wrapping post.

Described annular magnetic pole is laterally or vertically to assemble.

The utility model can take full advantage of the two poles of the earth magnetic force that electric current produces by electromagnet, and the existing permanent magnet DC motor of contrast exceeds half in the utilization of magnetic force, thereby realizes energy-efficient.
