MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 7.5KW.
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-A740-280K-CHT PDF FR-A740-280K-CHT PDF FR-A740-280K-CHT MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V FR-A740-280K-CHT PDF.
Frequency converter capacity: 3.7KW.
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 MITSUBISHI INSTRUCTION MANUAL.
Speed control method of fan and pump equippment 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 INSTRUCTION MANUAL FR-A740-280K-CHT Manual.
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. Max input / output points: 32 points.
