When using a frequency converter to drive a gear reduction motor, the range of use is limited by the lubrication method of the rotating part of the gear. When lubricating with lubricating oil, there is no limit within the low speed range; There is a risk of running out of lubricating oil in the high-speed range above the rated speed. Therefore, do not exceed the maximum allowable speed. When frequency converters drive wound rotor asynchronous motors, most of them utilize existing motors. Compared with ordinary squirrel cage motors, wound motor windings have lower impedance. Therefore, it is easy to experience overcurrent tripping caused by ripple current, so a frequency converter with slightly larger capacity than usual should be selected. Generally, wound motors are often used in situations where the flywheel torque GD2 is large, and attention should be paid to setting the acceleration and deceleration time. When driving a synchronous motor with a frequency converter, compared to a power frequency power supply, the output capacity is reduced by 10% to 20%. The continuous output current of the frequency converter is greater than the product of the rated current of the synchronous motor and the standard unit value of the synchronous traction current. For loads with high torque fluctuations such as compressors and vibrators, as well as peak loads such as oil pumps, if a frequency converter is selected based on the rated current or power value of the motor, there is a possibility of overcurrent protection action caused by peak current. Therefore, it is necessary to understand the power frequency operation and choose a frequency converter with a rated output current greater than its maximum current. When using a frequency converter to drive a submersible pump motor, because the rated current of the submersible pump motor is greater than that of a typical motor, the rated current of the frequency converter should be greater than that of the submersible pump motor. When the frequency converter controls the Roots blower, due to its high starting current, it is important to pay attention to whether the capacity of the frequency converter is large enough when selecting it. When selecting a frequency converter, it is important to pay attention to whether its protection level matches the on-site situation. Otherwise, dust and moisture on site will affect the long-term operation of the frequency converter. 15. Single phase motors are not suitable for frequency converter drive.
