The frequency converter developed and produced by our company is a power control device that achieves precise control of AC motors by changing the frequency and voltage of the motor's working power supply, and has significant advantages.

1. The frequency converter is just a speed controller

   Misconception: Believing that frequency converters are only used to adjust motor speed, ignoring their energy-saving, protective, and soft start functions.

   Fact: Frequency converters can save energy by 30% -60% by optimizing the efficiency of motor operation (such as avoiding "big horses pulling small cars"); Simultaneously equipped with overcurrent, overvoltage, and overload protection, extending the lifespan of the equipment.

2. All motors can use frequency converters

   Misconception: Believing that frequency converters are suitable for all types of motors (such as ordinary asynchronous motors, synchronous motors, and special environment motors).

   Fact: It is necessary to choose a frequency converter based on the type of motor (such as the insulation level that needs to be adapted for variable frequency motors) and load characteristics (constant torque/variable torque), otherwise it may cause efficiency decline or malfunction.

3. The frequency converter does not require maintenance after installation

   Misconception: Believing that the frequency converter is a "maintenance free" device and not checked for a long time.

   Fact: Regular cleaning of dust, inspection of cooling fans, and testing of capacitor aging are necessary, otherwise shutdown may occur due to overheating or component failure.

GuangDong Zhufeng Electric Co.,LTD established in 2004, is a national high-tech and energy save enterprise with approval by National Development and Reform Commission. Focusing on the development and production and sale of products of "energy saving and control speed and variable speed", Zhufeng has been a very good supplier for energy saving and automation control solutions.
