37kw PM Permanent Magnet Motor 1880*1180*1520mm Frequency Converter
37kw PM Permanent Magnet Motor
Frequency Converter VFD Compressor
Permanent magnetic frequency conversion air compressor features:
1. Low noise: frequency conversion system, most of the work is
lower than the rated speed of work, the host mechanical noise and
wear down to extend the maintenance and service life; fan also uses
variable frequency drive, can significantly reduce the air
compressor noise .
2. To reduce the impact on the grid: soft start, to avoid the
impact on the power grid; also avoid their own impact on the
mechanical; no AC contactor, no electrical contact fault.
3. Variable flow control: can work in a wide range of displacement,
in accordance with the actual use of gas to adjust the motor speed,
to control the displacement.
4. Any given pressure and constant gas supply: the user according
to the actual production plant gas demand pressure to set the
compressor pressure to avoid the unit above the gas pressure above
the waste operation.
5. No empty running current: pressure enough to unload the unit
will run after the air, but the unloading of empty run-time unit in
the consumption of 45% of the no-load consumption. In general, the
average unloading time is about 30% of the total running time, so a
common compressor of 37KW will waste 31968 kWh / year.
What factors contribute to demagnetization risk?
1. Permanent magnet motor temperature rating:
permanent magnet motor magnetic materials using NdFeB magnetic
materials, rare earth permanent magnet materials as the latest
development, due to its excellent magnetic properties and known as
the "magnetic king." Ingredients are: rare earth metal neodymium
29% -32.5%, metal elemental iron 63.95-68.65%, non-metallic element
boron 1.1-1.2% and other elements. Permanent magnet motor
performance there is an important indicator, namely: high
temperature level. More than its temperature rating, its magnetic
flux density will drop sharply. High-temperature grades can be
divided into: N series, resistant to more than 80 degrees; H
series, resistant to 120 degrees; SH series, resistant to more than
2. Motor protection class:
protection class is divided into IP23 and IP54. In this case, IP23
as a result of the temperature relationship can only be designed to
open the motor, air compressor many occasions the use of relatively
poor, dust, moisture, salt mist and other corrosive gases lead to
its low life. Especially the metal-containing dust into the motor
will seriously affect the magnetic distribution, resulting in
decreased efficiency. In this case,
While the high degree of protection of the IP54 motor to avoid the
