Frequency conversion motor frequency conversion refers to the standard conditions, with 100% extra load within 10% ~ 100% extra speed after operation, the temperature does not exceed the motor calibration of the permissible value. The frequency conversion motor in operation will have the power saving effect? Can save electricity mainly is to look at the operating condition of the equipment. If you are running at full capacity, without frequency conversion is the same. But to do the same power, the use of single-phase and three-phase 380 v, 220 in electricity charge standards, the former is to save money,The single-phase 220 power is generally small, the same power under the condition of current is larger than 380)。 1, energy saving, in order to ensure the reliability of the products, produce all kinds of machinery in the design with power drive, has the amount of surplus. The motor will not operate under full load, except to driving requirements, the rest of the torque increases the active power consumption, abuse of power, when the pressure is on the high side, can drop in motor speed, in the constant pressure of together to save power. When motor speed from N1 N2, the motor shaft power (P)As follows: the changes of P2 / P1 = (N2 / N1)3, thus it can be seen falling motor speed cubic level of energy saving effect can be obtained. 2, dynamic adjustment and energy saving: agility to adapt to the changes in load, maximum power supply voltage. Frequency conversion governor on software with 5000 times per second measurement output function, keep high output power of the motor running. 3, a function of V/F conversion itself power saving: in the case of ensure the motor output torque, can take the initiative to adjust V/F curve. Cut down the output torque of the motor, the input current, attaining a state of energy saving. 4, frequency with soft start saving energy: in total pressure motor, because of the motor torque needed, from the grid to absorb additional 7 times of motor current, and large currents (abuse power, harm to power grid voltage fluctuation is very big also, increase the line loss and damage. Choose soft launch, from 0 - a current-Additional motor current, cut the current impact on grid, save electricity, also reduced the launch inertial impact the great inertia of the rotating speed of the equipment, prolong the service life of the equipment.
