Connecting cable for handheld GOT and PLC.
Cable length: 1.5 meters.
Application: RS-422 connection (FX series). Power: 7.5kw.
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. MITSUBISHI inverter FR-F740 series MITSUBISHI Special Adapter Connection Board User's Manual.
Voltage level: three phase 400V FX3U-4DA-ADP
Frequency converter capacity: 450KW.
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 MITSUBISHI Special Adapter Connection Board User's Manual.
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.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity MITSUBISHI Special Adapter Connection Board User's Manual. MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 2.2KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion FX3U-4DA-ADP User's Manual.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation FX3U-4DA-ADP User's Manual. To this end, the matrix type of AC - AC variable frequency arises at the historic moment FX3U-4DA-ADP User's Manual.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitted.
It can achieve a power facctor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large FX3U-4DA-ADP Manual.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study MITSUBISHI Special Adapter Connection Board User's Manual.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve.
