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 FR-F740-2.2K-CHT
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 oof the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motor FR-F740-2 FR-F740-2.2K-CHT Manual . 2K-CHT PDF.
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) FR-F740-2.2K-CHT PDF.
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving. MITSUBISHI inverter FR-F740 series MITSUBISHI Instruction manual.
Voltage level: three phase 400V.
Frequency converter capacity: 280KW.
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 MITSUBISHI Instruction manual.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic toorque 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 MITSUBISHI Instruction mannual FR-F740-2 FR-F740-2.2K-CHT Instruction manual. 2K-CHT Manual .
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
