Product Description

The Energy saving compressor system is composed of a control panel, motor with sensor, pressure sensor, and a compressor. The current case is 220V AC/380VAC power supplying the controller to control the motor, meanwhile the motor sensor transfers the location signal to the controller. The pressure sensor in the compressor system transmit the pressure value to the controller, based on these pressure value, the controller carries on the real-time speed control. thereby achieve the function of constant pressure of the whole compressor system.

Moreover, the controllers can be connected to the buses, the controller can control different motors, if the pressure is insufficient, the other motors would work simultaneously to keep the constant pressure.

System chart of intelligent air compressor


You can refer to the system chart, once the pressure is reduced, the motor would speed up to boost, to keep the system pressure stable. Because controllers are connected to the buses. In case, the insufficient pressure that one compressor can’t meet, the system would open the compress 2, compressor 3,… intelligently. Opposite process can work as well. All the process is automatically, by close loop control. The intelligent system can help to saving energy and keep constant pressure.


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.

     


Moreover, we can produce customized motors by our various applications.


For a professional compressor case advices, please contact us at info@volcanomotor.com. 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.

Advantage of PMSM motors

  • Lower maintenance 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


For customized PMSM Motors, please contact our technician, Ordinary, we have to know the following information to get a professional proposal:

  • Brushed or Brushless   Customer preference

  • Output power (W)   Horsepower/watts/torque rated at full load speed

  • Voltage (V)   i.e 12v DC …….. 220v AC

  • Motor speed (RPM)   Revolutions per minute of the shaft at full load Voltage 

  • Application   e.g. traction, airconditioning, etc.

  • Duty     Most motors are rated continuous. Some applications however may use motors designed for intermittent duty

  • Configuration/Frame    Our products are according to IEC standard, we also can customize the flange and shaft according to the customer drawing 

  • Controller function     e.g. forward/reverse, variable speed, acceleration profile, etc.
