Brand:
MITSUBISHI
Name: 3 phase 200V converter
Model: FR-F720P-37K
"MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 37KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection).
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency,
The equipment to the power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, which is mainly used in the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply.
The general inverter is 1520 times inverter price.
The main device called "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter. "
Power: 110kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits MITSUBISHI FR-F720P-37K FR-F720P-37K
