PM VSD silent industrial air compressor price wholesale,40hp air compressor with CE certificate

The permanent magnet variable frequency air compressor is now a new energy-saving product on the market. His principle is that the working principle of the permanent magnet synchronous motor rare earth permanent magnet frequency conversion air compressor is the same as that of the electric excitation phase synchronous motor. The difference is that the former is Excitation is performed by replacing the field winding with a permanent magnet.

permanent magnet variable frequency air compressor advantage

1, permanent magnet variable frequency air compressor energy saving effect

The biggest part of the permanent magnet variable frequency air compressor is energy saving, generally energy saving 10% -35%, the amount of energy saving depends on the working condition of the air compressor and the setting of the parameters of the frequency converter. The biggest factor is the working condition of the air compressor. When the customer’s gas consumption is fluctuating, the energy saving effect is better. The most direct data is the ratio of the time of no-load to the total working time.

2, the maintenance cost of the permanent magnet variable frequency air compressor is reduced

Thanks to the energy-efficient control system, the software start-up of the air compressor reduces the electrical shock to the electrical components of the motor, and the starting current is small, which extends the life of the contractor of the motor. The software start-up of the air compressor reduces the mechanical impact on the equipment, and the motor bearings, main bearing and gearbox all extend the service life. The energy-efficient controller control device allows the air compressor to be loaded for most of the time. All kinds of related solenoid valves and pneumatic components greatly reduce the number of actions, so the failure of electrical and mechanical parts is greatly reduced.

3, the impact of permanent magnet variable frequency air compressor use on the power grid

When starting with the star triangle, the starting current is still relatively large. When the grid capacity of the factory is limited, it will cause the upstream air switch to trip. Using the high-efficiency energy-saving controller can save the cost of the expansion of the factory grid.

4, permanent magnet frequency conversion air compressor to reduce production losses

The permanent magnet variable frequency air compressor uses an energy-efficient controller. Colleagues monitor more than 20 parameters, current, voltage, speed, torque, and power consumption. The system is highly intelligent. Make the air system more stable and reliable, reduce the emergency time and reduce the loss of production.

5, permanent magnet frequency conversion air compressor to reduce noise

When the exhaust volume is reduced, the motor speed is slowed down, and the noise of the air compressor is much smaller than that at full speed. The time for unloading runs is reduced, and the noise of venting is also reduced.

permanent magnet variable frequency air compressor features

When the three-phase stater wingdings of the permanent magnet motor (each phase difference of 120° electrical angle) are supplied to the three-phase alternating current of frequency f, a rotating magnetic field that is shifted at the synchronous speed will be generated. In the steady state, the main pole magnetic field rotates synchronously with the rotating magnetic field, so the rotor rotational speed is also the synchronous rotational speed. The stater rotating magnetic field is kept relatively static with the main pole magnetic field established by the permanent magnet, and they interact and generate electromagnetic torque. The drive motor rotates and performs energy conversion.
