Four properties of Volcano Electric motors includes their efficiency, reliability, use of leading-edge technology, and the virtually limitless options, they provide for customization.
Variable speed motors in air compressors, because of the high efficiency at wide speed range, brushless DC motors are widely used at variable speed conditions.
This motor used in air compressor system, compared to asynchronous induction motor system. Thanks to its advantages listed below, which is to be used that have variable requirements provides up to 35% energy saving and improves the compressor’s service life.
High efficiency at variable speed
At constant speed that both asynchronous motor and permanent magnet DC motors can work at high efficiency. But using asynchronous motor, when the motor speed is changed, the motor efficiency goes down sharply, but using the permanent magnet DC, at a wide speed range, the motor efficiency keeps at a high efficiency.
Soft Start and Longevity
Excessive current drawn during the star-delta of the electrical motor (starting current) and the mechanic loads are eliminated thanks to the soft start and stop features of this system. As a result, longevity of the motor equipment improves and maintenance costs decrease.
Economical Run and Constant Output Pressure
Standard air compressors switch to idle when the targeted pressure is achieved and switch to load when the specific low pressure is reached. When the compressor switches to idle, the electrical motor keeps working at its constant speed and does not produce compressed air hence the compressor consumes 30% power of its load run. Pumps with our permanent magnet motor, works at an optimum speed (rpm) to meet the real time air needs and provides great deal of energy savings as well as producing targeted constant output pressure.
In some cases, because we can’t rule out the possibility of long run in full load condition, we have to order motors to meet maximum demands of compressors. But in actual operation, the proportion of light load running time is quite high, it leads to a lot of energy waste. From now on, with our permanent magnet motor system, you can order a motor at rated power, and peak power can meet the full load condition. By the close loop control, the motor speed is variable automatically by your pressure condition.
The configuration of these motors are exactly same to conventional electric motors, basically NEMA standard or IEC standard frame motors. Thus, these Brushless DC motors can replace the current motor system simply, but with much higher efficiency.
Moreover, we can produce customized motors by our various applications.
For a professional compressor case advices, please contact us at firstname.lastname@example.org. Our engineers are at your service case by case. You can try to tell us your compressor application, function requirements, efficiency etc. our permanent magnet motor pumps systems can easily replace the conventional 3 phase asynchronous electric motors with higher efficiency and intelligent.
Variable speed motors in air Compressors
Advantages of Brushless DC motor:
Lower Maintainance and longer lifetime - no brush and commutator erosion
Lower noise - the elimination of brush contact
Higher power to weight ratio
Higher efficiency ( in general higher than 90%)
Lower temperature rise - more efficient heat dissipation due to winding construction
Reduction of EMI
