Frequency conversion motor frequency is adjustable design, so motor manufacturers can produce a lot of high-speed motors, in high-speed operation can maintain the characteristics of constant torque, to some extent instead of the original medium frequency motor, the following Senforce motor Xiaobian will take you to understand, about the selection of frequency conversion motor.

       Variable frequency motorFor the three-phase AC synchronous or asynchronous motor, a frequency converter is installed, according to the output power of the frequency converter, there are three phases380Vperhaps220VSo there are different differences in the power supply, but in general,4KWThe following frequency converters are available220V; On account ofVariable frequency motorIt is based on the fundamental frequency of the motor to divide the different constant power speed regulation zone and the constant torque speed regulation zone, so the setting of the fundamental frequency point is very important.

       4stageVariable frequency motorThe base frequency operating point is designed in50Hz, frequency0-50Hz(Speed of revolution0-1480r/minRange of motor for constant torque operation, frequency50-100Hz(Speed of revolution1480-2800r/minWithin the range of the motor for constant power operation, the whole speed range is(0-2800r/minIt basically meets the requirements of general drive equipment, and its working characteristics are the same as DC speed regulation motor, and the speed regulation is smooth and stable. If you want to increase the output torque in the constant torque speed regulation range, you can also choose6Lv OR8Grade motor, but the volume of the motor is relatively large.
