2.3 Model and Selection Notation
SINUS MV
Standard MV VFD model selection depends on the motor type, load features, and motor current, voltage
In the case of the special load or special motor or special working environment, besides refer to rated power and
rated current of the motor, should abide by the following advices:
1. If load torque ripple such as compressor, vibrating machine and kneader is large, the practical process and the
working condition should be found out firstly, and that the rated current of the selected
SINUS MV
medium voltage
VFD is larger than the maximum current under the industrial frequency must be ensured.
2. Motor rated current used in submersible pump or submerged oil pump is usually greater than the rated current
of the motor; the rated current of
SINUS MV
Standard MV VFD should be larger than motor rated current.
3. The rated current of the selected
SINUS MV
Standard MV VFD which is used in the special fans, such as roots
fan, should be increased in proportion.
4. When one
SINUS MV
Standard MV VFD drives multiple motors at one time, the VFD which has the larger current
should be selected according to the total current of the motors.
5. For impacting load, such as oil pump, a proper enlarge of the capacity should be taken into account during
selection of
SINUS MV
Standard MV VFD.
6. When used in the extreme environments, such as high temperature or high altitude (>1500m),
SINUS MV
Standard MV VFD should be derating, and one level higher VFD should be selected.
2.4 Application Industries and Fields
SINUS MV
Standard medium voltage VFD series is widely used in various fields in national economy, exported
to Europe, Middle East, Southeast Asia etc., and has a good reputation. Perfect solutions for soft start, speed
adjusting, energy saving and intelligent control of medium voltage AC motors (including synchronous and
asynchronous motors) could be supplied to customers.
Typical application industries are:
●
The above advice do not cover all of the cases of special loads and motors. Please contact with
Santerno
to confirm the model selection of
SINUS MV
Standard MV VFD.
●
If the working condition demands of explosion-proof,
SINUS MV
Standard MV VFD should be
placed at safety site because that it has no explosion-proof design.
