Compressor special bearing-free direct connection non iron-core rare-earth permanent magnet motor
Technical field
This utility model relates to permanent magnet motor, the non iron-core rare-earth permanent magnet motor that a kind of compressor using bearing-free direct connection is special.
Background technology
At present the compressor major part in Chinese market uses conventional asynchronous motor, with the coupling method of compressor host head also based on belt transmission and shaft coupling transmission.Its shortcoming is obvious: volume is big, and efficiency is low, and energy consumption is big, and fault rate is high, need to often safeguard.
Rare earth permanent magnet non iron-core motor is that a kind of new special motor representing electromechanics trade future thrust uses non iron-core, brushless, without magnetic damping, rare earth permanent magnet technology, change conventional motors and use stalloy and winding stator structure, make electric system efficiency bring up to more than 96%.
Rare earth permanent magnet non iron-core motor is a great innovation, technically achieves " three is big " and breaks through, and one is compared with the design of conventional radial magnetic field structure, have employed the design of axial magnetic field structure, increases substantially power density and torque volume ratio.Two is to use novel winding technique, high voltage precision die cast and macromolecular material, effectively reduces winding copper loss.Three is not use stalloy as stator and rotor core material, eliminates magnetic damping and iron loss, reduces driving power, decreases iron loss pyrotoxin.
Comparing with conventional motors, rare earth permanent magnetic non-iron-core motor has " four is big " performance advantage: one is energy-efficient.Motor power factor is high, and without iron loss, without magnetic damping, efficiency is greatly improved.The actual application attestation of user, uses 1.5 kilowatts and 3 kilowatts of diesel electric power plants of this technology, and compared with conventional electric generators, rate of economizing gasoline reaches 40%.Two is light material-saving.Volume is little, and weight only has the part of conventional motors.The steel of 80%, the stalloy of 100%, the copper material of 50% can be saved.Three is that speed governing is good.Motor speed and supply frequency keep constant, can simplify frequency-converting speed-governing control system, speed-regulating range width, and precision is high;Easily make multipole, low speed heavy-duty motor, the drive system such as gear-box, belt pulley can be cancelled, it is achieved directly drive.Four is highly reliable.It is low that motor runs temperature rise, motor winding employing macromolecular material precision insulation-encapsulated technology, and good environmental adaptability is reliable.
Compared with currently advanced rare-earth permanent-magnet electric machine, in hgher efficiency, weight is lighter, stability is more preferable.Have that the structure identical with general asynchronous motor is easily installed, starting torque is big, overload capacity is strong, efficiency is high, power factor is high, stable, low noise, maintenance are simple, function admirable.
Rare earth permanent magnetic non-iron-core motor development prospect is wide, according to initial estimate, if newly-increased motor has 1/3rd to substitute with this novel product, can economize on electricity every year nearly 50,000,000,000 kilowatt hours, save stalloy 500,000 tons, copper 20,000 tons, the output value of nearly 10,000,000,000 yuan, economic benefit and social benefit can be created the most considerable.
At present, small-power rare earth permanent magnet non iron-core motor has been produced in batches and has been obtained popularization and application in terms of small-size wind power-generating, diesel generation, electric tool.But also in demonstration phase in, on heavy-duty motor.
Through retrieval Chinese patent, the invention of relevant motor much, uses the special non iron-core rare-earth permanent magnet motor of the compressor of bearing-free direct connection but without a kind of involved by the application.
