DOS/V computer (D-SUB 9 pin)MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
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 FX2NC-96MT-DSS PDF FX2NC-96MT-DSS
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 FX2NC-96MT-DSS PDF.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. MITSUBISHI inverter series: FR-A800 FX2NC-96MT-DSS PDF.
Voltage level: three phase 400V.
Power: 450kw.
SLD converter rated current: 1094A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
To maximize the performance of the motor.
Advanced auto tuning function.
The newly developed PM motor auto tuning feature can be used to operate other manufacturers of PM mootors (Yong Ci synchronous motors) in the sensorless state MITSUBISHI HARDWARE MANUAL FX2NC-96MT-DSS Manual.
Not only can drive MITSUBISHI induction motor and PM motor, but also can drive other manufacturers of induction motor and PM motor.
This means that you can reduce the cost of inventory and supplies MITSUBISHI HARDWARE MANUAL.
If the PM motor is produced by a IPM motor or other company using MM-CF, the starting torque is limited to 50%,
Even after tuning is not simple to use and positioning control of zero speed torque) induction motor and permanent magnet motor can be combined freely MITSUBISHI HARDWARE MANUAL. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 1.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the raated current, therefore, the impact on the mechanical and electrical FX2NC-96MT-DSS HARDWARE MANUAL.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120%% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FX2NC-96MT-DSS Manual.
