MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 400KW.
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 FR-F820-00930-2-60
FR-F820-00930-2-60
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 MITSUBISHI FR-F820-00930-2-60.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 7.5KW.
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 MITSUBISHI FR-F820-00930-2-60.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) MITSUBISHI IPM motor.
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter MITSUBISHI IPM motor.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 30kw.
SLD converter rated current: 77A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
