What Is A Variable Speed Drive And How Does A Variable Speed Drive Work?

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, variable speed 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 control products, variable speed inverter has been widely used.

Variable Speed Drive Applications

About a third of the world's energy is spent on the AC motor drives that drive constant-speed centrifugal pumps, fans, and compressors, but the market penetration of inverter variable speed drive is still low. Bu using inverter variable speed drives, the energy efficiency can be improved significantly, and this is why people choose to use variable frequency drives. In order to meet different kinds of requirements, different types of frequency inverter drives are also developed. Variable speed drives in Micno VFD including low voltage inverters, medium voltage vfds, high voltage inverter and Industrial Inverter, you can choose different variable speed drive applications to choose a different frequency converter drives.

How To Select Variable Speed Drives?

  • Confirm the voltage and power of the motor.

  • Confirm the type of the load (light duty or heavy duty). If the load is light duty, please keep the same specification with the motor. If the load is heavy duty, please choose an inverter with a higher specification than the motor.

  • Verify the current of the motor. Inequality: the current for normal running > the rated current of selected model*1.1. If the above inequality holds, please choose an inverter with a higher current until the above inequality doesn't hold. If the above inequality holds, please keep the same specification with the motor.

  • Ambient Temperature and Altitude. If the working environment is exceeds the specified range, please contact our technician to choose the correct model.
