FR-D720-04K MITSUBISHI FR-D720-04K The control of asynchronous motor is realized through the corresponding inverse coordinate transformation 3 phase 200V converter

Brand: MITSUBISHI
Name: 3 phase 200V converter
Model: FR-D720-0.4K
MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.4KW.
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 motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation.

MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible MITSUBISHI FR-D720-0 FR-D720-0.4K4K.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced MITSUBISHI FR-D720-0.4K.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Power: 18.5kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose MITSUBISHI FR-D720-0.4K. ) Use: dialog type LCD display parameter unit.
Applicable frequency converter: FR-A700, FR-F700, FR-E700, FR-D700. Power: 45kw.
Purpose: to suppress the power harmonics MITSUBISHI 3 phase 200V converter.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current MITSUBISHI 3 phase 200V converter.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 1.5kw.
SLD converter rated current: 3 MITSUBISHI 3 phase 200V converter. 8A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption. FR-D720-0.4K.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control MITSUBISHI FR-D720-0.4K.
