MITSUBISHI FR-E720-7.5K Product information and technical parameters:
Brand: MITSUBISHI
Name: 3 phase 200V converter
Model: FR-E720-7.5K
MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 7.5KW.
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.
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.
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.
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-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 110KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes FR-E720-7.5K.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) FR-E720-7.5K
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall FR-E720-7.5K. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.4KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FR-E720-7.5K. Power: 37kw.
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. Power: 7.5kw.
Voltage: 200V.
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 series: FR-F840.
Voltage level: three phase 400V.
Power: 37kw.
SLD converter rated current: 77A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characterisstic drive motor FR-E720-7.5K.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-E720-7.5K.
