VDS SERIES
VDS 10 - 350
PERMANENT MAGNET MOTOR
VSD SCREW AIR COMPRESSOR
7.5 kW-250 kW
Permanent Magnet Motor
lPM motor with high-performance neodymium
iron boron (NdFeB) magnets
lThe service life is more than 15 years
lCancels the loss of the excitation system which
improves efficeency 5%-12%
lThe level 1 energy saving PM motor
lCompact structure,Small size,Light weight
it cancel the excitation winding and the excitation ]
power(magnetic pole core),the structure is simple
reliable operation and easy maintain
lHigh precision ,fast response,bigger starting torque
Smooth start
No generating surge current
1. Through system control, the characteristic of
variable frequency drive is that the motor starts
smoothly
2. The motor always runs below the rated current
3. Effectively avoid the expensive cost of surge
current generation
Constant pressure control
1.Provide the necessary amount of air with the
necessary pressure
2.the pressure is stable below +/-0.1bar.
3.Saving eneryg ,no pressure loss energy
sconsumption
Energy Saving Solution
Compared with the fixed speed compressor,PM-VSD compressor,
can save electric charge more than
75,356 kWh/year.
52,123kw.h+9,680kw.h+13,552kw.h=75,356kw.h/year
(abvoe data is the 37kw screw air compressor industry data.your factory actual saving value is depends on actual using condition)
Smart inverter
Advanced motor control technology,
A wide speed control range of frequency
converter prevents unnecessary power
consumption for no- load operation
Permanent magnet motor
High efficiency ,IE3 Permanent magnet
motor reduce energy costs
No unnecessary pressure
Constant pressure setting reduce the pressure
drop,1 bar of unnecessarily high pressure
corresponds to about 7% of the energy
Lossless direct drive
The direct connect in between the air-end
and motor has reduce transmission loss for
100% efficiency
Visible Cost Reductions
When purchasing industrial air compressors, adopt a forward-looking approach by prioritizing total lifecycle costs—including energy efficiency, maintenance,and operational expenses-over mere upfront purchase price.
This strategic perspective ensures long-term value and sustainability
Why Energy Efficiency
Energy costs represent about 77% of the total operation costs of your compressor. Thatis why efficiently reducing the energy consumption of your compressed air installation should be a major focus.
Why Variable Speed
As a majority of customers have a variable demand for compressed air ,variable speed compressor is superior VS fixed speed compressor in terms of energy saving by perfectly
matching air supply to air demand of avoiding unloading losses.
Why Permanent Magnet Motor
Permanent magnet is a high efficiency motor combines our variable speed technology with our new and highly efficient drive train, resulting in energy saving of up to 40%.
HIGH QUALITY KEY COMPONENTS
Ensuring product quality, stability, efficiency, and energy efficiency
RELIABLE AIR-END
lOver Sized Air-end , Low Speed ,No Overheat Problem
lThe screw air-end is the core, with high-precision rotors ensuring
enhanced stability, longer lifespan, and higher energy efficiency.
l8 sets of SKF brand bearings ensure the stability and long service
life of the compressor air- end.
