Mitsubishi inverter in energy-saving principle

1, variable frequency energy-saving:

Motor can’t operate under full load, except for the power drive requirements, the excess torque increases the power consumption, resulting in the waste of electric energy, in the high pressure, can reduce the <a href="/searchfanan.html?search=motor&select=7">motor running speed, so that it can save energy at the same time.

When the motor speed from N1 to N2, the motor shaft power (p) changes as follows:

P2/P1 = (N2/N1) 3, thus reducing the motor speed can be cube-level energy saving effect.

2, dynamic adjustment of energy saving:

Quickly adapt to load changes, supply the maximum efficiency voltage. The frequency conversion speed regulator is equipped with 5000 time / second measurement and controlling output function, and the output of the motor is always kept in high efficiency.

3, through the frequency conversion of its own V/F function:

In the case of the output torque of the motor, the V/F curve can be adjusted automatically. Reduce the output torque of the motor, reduce the input current, to achieve energy saving.

4, variable frequency soft start energy-saving:

When the motor full voltage is started, due to the need for the starting torque of the motor, to absorb 7 times the motor rated current from the power grid, and large starting current is a waste of electricity, to the grid voltage fluctuations damage also greatly increased the line loss and damage. After the soft start, the starting current can be obtained from the 0 - motor current, reducing the impact of the starting current to the grid, saving the electricity, also reducing the impact of inertia on the device's large inertia, and extending the service life of the equipment.

5, improve power factor energy saving:

The motor is generated by the stator winding and the rotor winding through the electromagnetic force. Because of the effect of winding inductance. For power grid, the impedance characteristic is sensible, and the motor absorbs a large amount of reactive power at the time of operation, resulting in low power factor

After adopting the frequency conversion energy saving speed regulator, the performance has been changed to:

AC--DC--AC, Rectifier filtering, load characteristics have changed. Frequency converter on the grid impedance is resistive, high power factor, reduce reactive losses.
