Products to ensure stable and accurate operation in a wide variety of applications.
Enhanced real-time sensorless vector control and vector control functions, can meet the needs of various kinds of machinery and equipment.
For paper, textile, wire, a variety of tape and other products of the extension of the machine processing, linear speed control is essential.
It can respond quickly to the change of production line speed and avoid the phenomenon of uneven winding.
This helps to achieve a stable supply of high quality products.
MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 18.5KW.
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%) MITSUBISHI FR-A840-00770-2-60
FR-A840-00770-2-60
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).
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 FR-A840-00770-2-60. MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 2.2KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus MITSUBISHI FR-A840-00770-2-60.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy MITSUBISHI Battery trunk cable.
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure MITSUBISHI Battery trunk cable.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements. "MITSUBISHI inverter FR-F740 series MITSUBISHI Battery trunk cable.
Voltage level: three phase 400V.
Frequency converter capacity: 5.5KW.
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 pprocess is called rectification FR-A840-00770-2-60.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixeed frequency and a certain voltage of the inverter MITSUBISHI FR-A840-00770-2-60.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "
