Frequency conversion motor frequency conversion motor is under the standard conditions, with 100% rated load continuous operation within the scope of 10% ~ 100% of rated speed, temperature does not exceed the motor calibration of the permissible value. Frequency control of motor speed has become the main stream speed control scheme of stepless variable speed drive can be widely used in all walks of life. Especially with the inverter increasingly widely used in industrial control field, the use of variable frequency motor is also increasing, it can be said as variable frequency motor is relatively common in terms of frequency conversion control, the advantages of all use frequency converter where we are not difficult to see the figure of variable frequency motor. Frequency conversion motor under what circumstances to complete the effect of frequency conversion? You just need to regulate the frequency of the inverter frequency conversion motor changes the speed of the motor, its corresponding principle: simple said is through the control to change the compressor speed, so as to reach the purpose of save electricity, frequency conversion strengths as follows: 1. Small starting current, rotate speed gradually speeding up, the starting current is customary 1/7 of the air conditioning; 2. Without the problem of hot and cold, because the frequency conversion air conditioning is close to the set temperature and rotational speed gradually decreases with temperature, gradually reach the set temperature and stick to work with loss of balance of cold energy of low frequency, is the indoor temperature stability; 3. Noise is lower than convention air conditioning, due to the double rotor compressor frequency conversion air conditioning use, greatly decreased the cyclotron is not balance, make outdoor and smaller oscillation, about half of the air conditioning for practice.
