PERMANENT MAGNET VARIABLE FREQUENCY SCREW AIR COMPRESSOR

GOODDEER Electric motor drive High efficient permanent magnet variable frequency screw
air compressor

The advantages of permanent magnet motors over ordinary motors.

High efficiency: the system loss of the excitation motor is eliminated and the
efficiency is improved

High efficiency at low load: PM motors are more than 9% higher than conventional
asynchronous motors at full load, and their energy efficiency remains the same as the speed decreases.

Large starting torque: The ratio of the maximum power distance of the permanent magnet
synchronous motor to the rated distance can reach more than 3 times.

And the general asynchronous motor is only 1.6 times

More stable control: the response time of the permanent magnet motor is less than 50ms,
and the gas production can be adjusted in a wide range in an instant

This makes our rotor have the following advantages

Small Drop and High Efficiency

The tooth profile drop of the compressor is 25% less than that of the four six ratio
rotor.

The small drop means that the effective compression efficiency can be greatly improved

Equal stiffness

The main rotor has high speed and large diameter, and the auxiliary rotor has low speed
and small diameter.

The diameter ratio of the main engine profile rotor is directly proportional to the
speed ratio.

This design makes the stiffness of the two rotors completely equal stiffness.

Small leakage area

The leakage area brought by the large rotor is small, which further improves the
compression efficiency

Sophisticated equipment

We use Britain horryd rotor special processing machine and Germany Kapp precision rotor
grinder.

The accuracy of tooth profile can reach 0.005mm, and the surface roughness can reach
Ra0 1-0.2mm

Through the strict inspection of Germany ZELSS and LEITZ coordinate measurement.

the rotor maintains the best clearance value even under continuous operation, which is
stable and efficient.

Intelligent design

The intelligent microcomputer control system can accurately control the operation of
each component of the unit . collect operation data parameters at the same time.

It has the functions of automatic diagnosis, display, alarm and protection, and can
realize 24-hour unattended work

Powerful protection function,

complete fault alarm and shutdown function. In case of any fault, stop the machine
immediately to detect the text, diagram and voltage, s

o as to realize the protection of the unit.

Excellent communication joint control function,

RS485 communication function supports the reserved communication interface of modus RTU
protocol, which can connect corresponding equipment according to different needs of users, and
realize linkage control and remote control through the upper computer

Silent Environment

Silent case design ,even in the noisy city can maintain a good noise level, to avoid
noise caused by environmental pollution.

High temperature design

The equipment can operate well at ambient temperatures up to 48 C
