The energy-saving effect of inverter motors is the main factor recognized by the market!?

The frequency conversion motor can be combined with the load change to achieve the constant demand of torque or power under different frequency conditions, and under unstable load conditions, the adjustment function of the frequency conversion motor realizes the principle of on-demand distribution, and better avoids energy waste.

When the motor is running under a non-rated load, if a power frequency motor is used, the supersaturated torque (such as the fan adjusts the damper to reduce the air volume, while the motor speed remains unchanged, and the output torque is not proportionally reduced with the decrease of the air volume) increases the power consumption, while the frequency conversion motor can effectively save energy through the adjustment of speed.

The frequency converter equipped with the frequency conversion motor has a fast response function to load changes, so that the motor is always running in a high efficiency state. The unique dynamic adjustment function of the inverter motor greatly expands the application field of the inverter motor, especially when applied to the fan pump industry, and the energy-saving effect is extremely significant.

When the power frequency motor starts at full voltage, the motor should absorb 5-7 times the rated current from the power grid, which not only wastes electricity, but also has a great impact and damage to the power grid. When using frequency conversion starting, the starting current can be adjusted by frequency modulation, on the one hand, there is no impact problem of starting current on the power grid, on the other hand, the impact of starting inertia on the equipment is reduced, and the service life of the motor and equipment is prolonged, which is also the reason why soft starters are widely used.

Relatively speaking, the power factor of the frequency conversion motor is high, which greatly reduces the waste of power grid resources, and the reason why the state encourages and promotes the application of frequency conversion motor, in addition to the long-term layout of energy saving, alleviating the pressure on the power grid is also one of the booster factors.

It is undeniable that the quality of the inverters supporting the motors at present is uneven, and some of the inverters with poor quality. It has a particularly great impact on the performance of the motor, causing the motor to burn out due to the heating of the windings in a short period of time. For this reason, the insulation level of the frequency conversion motor should be higher than that of ordinary motors, and the winding should use the special electromagnetic wire for the frequency conversion motor.

In the actual use of the motor, there are many customers who directly convert the frequency of ordinary power frequency motors to achieve more satisfactory use results. However, not all working conditions are applicable, and sometimes there are many problems. Because usually the actual output of the inverter is a rectangular wave, containing a lot of high-frequency components, the impact on the motor insulation is very large, and the winding failure rate is particularly high; On the other hand, when the speed regulation range is wide, the motor ventilation and heat dissipation conditions deteriorate, the heat generation may be very serious, and there are many cases of overheating and burning the winding. Therefore, when the power frequency motor is directly used as a frequency converter motor, it is necessary to fully estimate the adverse impact of the frequency conversion power supply on the power frequency motor, and replace it with a frequency conversion motor in time if it cannot operate normally and stably as expected.
