MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 500KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-BU2-7 FR-BU2-7.5K5K.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor FR-BU2-7.5K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 5.5KW.
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 FR-BU2-7.5K.
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.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Power: 15kw.
Voltage: 400V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. Power: 37kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installedd in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FR-BU2-7.5K.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motorr power used to select the DC reactor FR-BU2-7.5K.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
