MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 11KW.
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%) FX1NC-16MT PDF
FX1NC-16MT
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer) FX1NC-16MT PDF.
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. MITSUBISHI inverter FR-A720 series FX1NC-16MT PDF.
Voltage level: 3 phase 200V.
Frequency converter capacity: 5.5KW.
Inverter output for the PWM wave, containing more harmonic.
Frequency conversion power sensor through the input voltage and current signals to exchange sampling,
Sampling value through cable, optical fiber and other transmission systems and digital input frequency conversion power analyzer,
The sampling value of the voltage and current is calculated by the digital input frequency conversion power analyzer,
It can obtain the parameters such as voltage effecttive value, current effective value, fundamental wave voltage, fundamental current, harmonic voltage, harmonic current, active power, fundamental wave power and harmonic power MITSUBISHI PROGRAMMING MANUAL II MITSUBISHI PROGRAMMING MANUAL II FX1NC-16MT Manual. Power: 3.7kw.
Voltage: 200V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor MITSUBISHI PROGRAMMING MANUAL II.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 315KW.
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.
Why is the frequency of the inverter voltage proportionall 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 mmotor FX1NC-16MT Manual FX1NC-16MT PROGRAMMING MANUAL II.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
