About Variable Speed Drive 

Variable speed drive is an inverter motor speed control device which uses frequency conversion technology and microelectronics technology to control ac motor by changing the frequency mode of motor power supply. The inverter variable speed drive is mainly composed of rectifier (ac to dc), filter, inverter (dc to ac), braking unit, driving unit, detection unit microprocessing unit and so on. The adjustable speed ac drives adjusts the voltage and frequency of the output power supply through the internal IGBT switch according to the actual needs of the motor to provide the power supply voltage, so as to achieve the purpose of energy-saving, speed regulation. In addition, the electrical ac drives have a lot of protection functions, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of industrial automation, variable speed inverter has been widely used.

MICNO provides a variety types of high voltage inverter, low voltage sc inverter and industrial frequency converter for different industrial applications.

Applications of Variable Speed Drives

Variable Speed Drives are used in a wide range of applications, from small household appliances to large mine grinders and compressors. About a third of the world's energy is spent on the motors that drive constant-speed centrifugal pumps, fans, and compressors, and the market penetration of inverter variable speed drive is still low. The significant improvement of energy efficiency is one of the main reasons to use inverter variable speed drive. In order to meet all kinds of requirements, types of frequency inverter drive are also quite rich. Variable speed frequency drive in our company including Low voltage inverter,Medium voltage inverter, High voltage inverter and Industrial Inverter, according to the use of different places or objects the flexibility to choose a different frequency converter drive.
