The function advantage of YVP frequency conversion speed regulation three phase asynchronous motor
One of the three-phase asynchronous motor family has the function of frequency conversion, abbreviated to YVP frequency conversion motor, also known as frequency conversion speed regulation motor, frequency conversion speed regulation three-phase asynchronous motor.
The function advantage of YVP frequency conversion speed regulation three-phase asynchronous motor is that if the resistance value of stator and rotor can be reduced on the motor itself, the equipment can adapt to frequent speed change under different working conditions and long-term low-frequency working conditions. And to a certain extent, it is conducive to energy conservation and environmental protection.
Why do three-phase induction motors with frequency conversion and speed regulation have these functions compared with ordinary induction motors? Because the variable frequency motor has the function of variable frequency, and the realization of variable frequency function is that the structure of the motor is different from that of the ordinary motor. The variable frequency motor can adjust the load by changing the supply frequency, so it can reduce the power consumption and reduce the loss, which is beneficial to prolong the service life of the equipment.
It is also understood by some friends that YVP variable frequency motor is a general designation of motor driven by frequency converter. The three-phase asynchronous motor with frequency conversion and speed regulation is an organic combination of motor and frequency converter. The speed and torque of the motor are controllable. The speed and torque of three-phase asynchronous motor are fixed. The variable frequency motor can be adjusted within its speed range at will, and the motor will not be damaged, which is the difference between the variable frequency motor and the ordinary motor. Generally, most of the domestic ordinary motors can only operate under the condition of AC380V / 50Hz. The ordinary motors can be used for frequency reduction or frequency rise, but the range cannot be too large, otherwise the motors will heat up or even burn out.
Moreover, when purchasing variable-frequency motor, the construction also purchases frequency converter. The above also shows that the frequency converter and variable-frequency motor together can realize the function of variable-frequency speed regulation. If you don't use frequency converter, it doesn't make sense to purchase frequency converter motor.
