The utility model has the advantages of simple structure, high reliability, long service life, stable output voltage and current and saving energy greatly.

Description

A kind of electricity generation and electric welding motor
(1), affiliated technical field
The utility model relates to a kind of power supply and electric welding multipurpose plant, particularly a kind of electricity generation and electric welding motor.
(2), technical background
At present, for traditional electricity generation and electric welding motor, excitation field in the electricity generation and electric welding motor passes to electric current by excitation winding and additive excitation winding and produces, and therefore will consume certain energy in the excitation process, and the consumption of these energy has reduced the electricity generation and electric welding efficiency of motor.When these Conversion of energy are heat, improved the temperature rise of electricity generation and electric welding motor again.In addition, because the excitation winding of electricity generation and electric welding motor is arranged on the rotor usually, for giving the excitation winding power supply of rotation, generally be to realize by brush and slip ring system, again since brush useful life ratio engine short many of life-span, this just makes the reliability of operation of electricity generation and electric welding motor reduce greatly.And brush and slip ring produce the relative motion of arriving very much in the rotation along with rotor in service of electricity generation and electric welding motor, under the situation of energising, can produce electric spark, and surrounding environment is produced electromagnetic interference.
(3), summary of the invention
The purpose of this utility model just provides a kind of simple in structure, good reliability, long service life, output voltage and current stabilization, Remarkable Energy Saving electricity generation and electric welding motor.
The purpose of this utility model is to realize by such technical scheme, it includes casing, stator and rotor, it is characterized in that: rotor includes rotor block and armature spindle, armature spindle is arranged on the rotor block, along being provided with a plurality of magnetic poles on the circumference of rotor block uniformly, lay respectively between two magnetic poles at a plurality of permanent magnets that are provided with on the rotor block.
The utility model is work like this: the right-hand member of armature spindle directly is assemblied on the power output shaft of engine, engine rotation drives armature spindle and rotates, the armature spindle that rotates drives rotor block and rotates, rotate thereupon in the magnetic field that permanent magnet produced on the rotor block, the magnetic field and the stator that rotate relatively rotate, winding cutting magnetic line on the stator induces induced electromotive force, externally power supply.Because permanent magnet evenly distributes, number is more, therefore can continuously produce stronger alternating current.
Owing to adopted technique scheme, the utlity model has following advantage:
1. electricity generation and electric welding electric efficiency height, energy-saving effect is remarkable.Because the utility model adopts permanent magnet to produce magnetic field, need not consumed energy in the excitation process, so the utility model energy-saving effect is remarkable, electricity generation and electric welding electric efficiency height.
2. permanent magnet excitation does not produce heat, need not to install the excitation wire group on the stator, and the stator current load declines to a great extent, and heating is few, so bearing capacity is strong, is adapted at working under the adverse circumstances.
3. because the utility model adopts permanent magnet to produce excitation field, need not structures such as brush, collector ring, so simple in structure, reliability and life-span are much better than conventional electro-magnetic motor.
4. output voltage stabilization, multistage generation stabling current.
5. the utility model is coaxial integrative-structure, has saved transmission of power intermediate link, has improved reliability, reduces failure rate, directly is connected with engine, and unit volume dwindles, and performance improves, and loss reduces.
