"MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
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 device is the first power of the AC power conversion to DC (DC), the process is called rectification FX3UC-96MT/D Basic & Applied Instructions Edition Manual FX3UC-96MT/D PROGRAMMING MANUAL FX3UC-96MT/D
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, mainly used in three-phase asynchronous motor speed control, and also called frequency governor FX3UC-96MT/D Basic & Applied Instructions Edition Manual FX3UC-96MT/D PROGRAMMING MANUAL. "MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 15KW.
Inverter general area of domestic enterprises to occupy more than 80% of the market share,
Production of frequency converter, motor soft starter and other industrial automation control of the manufacturers, the use of heavy-duty design products,
Overload capacity, with super large start and running capacity, improve the automatic detection, protection and control performance,
Can start and control any type of heavy duty motor,
Products have been widely used in metallurgy, mining, paper, chemicals, building materials, machinery, electricity, and construction systems and other industrial transmission areas FX3UC-96MT/D Basic & Applied Instructions Edition Manual FX3UC-96MT/D PROGRAMMING MANUAL. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motorr excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor conttrol method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FX3UC-96MT/D Basic & Applied Instructions Edition Manual FX3UC-96MT/D PROGRAMMING MANUAL FX3UC-96MT/D Basic & Applied Instructions Edition Manual FX3UC-96MT/D PROGRAMMING MANUAL.
