1. Inverter speed control system, is it necessary to adjust the speed from 50HZ to 0HZ?
2. If the normal speed regulation range of your speed control system is between 5HZ and 25HZ, then the system can be modified to run between 25HZ and 50HZ;
3. This is the appropriate use of the transmission speed ratio, so that the operating frequency of the inverter falls in the high frequency band, which will reduce the impact of low frequency cooling;
4. The operating frequency of the inverter falls to a high frequency band, and the operating efficiency of the motor is improved, that is, the operating efficiency of the system;
5. When the frequency conversion motor runs at the power frequency, its efficiency is low, which is not as good as ordinary motor;
6. Ordinary motor is a university motor, and variable frequency motor is not a high efficiency motor;
7, so I recommend the use of: output reactor + ordinary asynchronous motor + cooling fan method, flexible and convenient, and less investment;
