In the past, the motor of Dongyuan variable frequency motor used with frequency converter was not designed individually, but used as a general motor. At that time, only considering the motor power supply, the possible harmonic distortion in the voltage or current waveform < P >, resulting in the undesirable phenomenon of overheating and noise. However, the technology of frequency converter is changing with each passing day, and with the emerging new design and different applications, many heart problems (such as temperature difference of motor, excessive noise and insulation damage caused by vibration) have arisen. In view of this, our company has developed and manufactured a special motor for frequency converter according to the characteristics of frequency converter to solve the common problems of motor/frequency converter in use.
For any drive system with variable frequency, the necessary conditions for smooth operation-power system, inverter system, motor characteristics and the demand of driving load should be well adjusted, so only a good combination of motor and inverter can ensure the success of system application.
