Description
Technical field
The present invention relates to technical field of motors, more particularly, to a kind of p-m rotor, magneto and compressor.
Background technology
Motor is the driving device of the various equipment such as wind turbine, pump, compressor, lathe, conveyor, weaving loom, extensive use
It is that the power consumption of power consumption maximum is mechanical in multiple industries such as metallurgy, petrochemical industry, chemical industry, coal, building materials, public utility and field.According to
Statistical calculation, 2011, about 1,700,000,000 kilowatts of China's motor ownership, about 3,000,000,000,000 kilowatt hour of total power consumption, accounted for the total electricity consumption of the whole society
The 64% of amount, wherein industrial circle motor total electricity consumption is 2.6 trillion kilowatt hours, accounts for the 75% of commercial power.
At present, there is the problem of the following aspects during motor use.First, in motor application operating mode, bear
Load rate is often all insufficient so that electric efficiency is very low.For example, it is maximum pressure that the universal type selecting of air compressor is obtained in textile mills
7.5bar, due to the upgrading of weaving loom and the consciousness reinforcement of energy-saving and emission-reduction and the needs for reducing cost, present textile mills make
It is usually 4bar~5bar with compressed air pressure, the load percentage for the air compressor for being thus declines, and electric efficiency is big
Width declines, and the phenomenon of " low load with strong power " that makes is even more serious.
Secondly, asynchronous machine is widely used, and asynchronous machine rotor winding can consume part electric energy, the loss in the form of generating heat
The 20%~30% of motor total losses is accounted for, the efficiency of motor reduces, while influences the service life of motor.Meanwhile rotor around
Group exciting current is in inductance current after converting to stator winding, the electric current into stator winding is lagged behind one angle of network voltage
Degree, causing the power factor of motor reduces.
Again, during starting asynchronous motor, it is desirable to which motor has sufficiently large starting torque, but wishes that starting current should not
It is too big, in case power grid produces excessive voltage landing and influences the normal fortune of other electric machinery and apparatus being connected on power grid
OK.In addition, when starting current is excessive, motor will be made to be done power be subject to excessive electricity in itself and impacted, if often start, also make around
The danger of group overheat.Therefore, the starting design of asynchronous machine is often faced with dilemma.
To sum up, conventional asynchronous motor is low there are power factor, and motor working efficiency is low, and starting current is big, and it is steady to influence power grid
It is fixed, the problem of rotor windings consume electric energy in the form of generating heat, motor service life is impacted etc..To solve the above problems,
Propose the concept of permanent magnet synchronous motor, i.e., in the structure of conventional asynchronous motor, by the way that rotor windings are changed into p-m rotor,
Form permanent-magnet rotor synchronous motor.Magnetic flux can be provided to motor by p-m rotor, induce electromotive force in the stator windings,
Exciting current is reduced, so as to can both improve motor power factor, improves motor working efficiency, starting current diminishes, and starts and turns round
Square increases, while can reduce the thermal energy consumption of rotor windings, extends motor service life, and energy-saving effect protrudes.
But in the actual production process, between permanent magnet and iron core, bonded by glue, under motor low-speed situations,
Glue bonds can be with normal use, or can use the long period, but works as under motor high-speed case, is specifically greater than
When 3500 revs/min, for glue under huge centrifugal force effect, while in the case of a high temperature, glue failure, causes permanent magnet
Drop, so that magneto breaks down.
