A variable frequency drive is also called as AC drive, variable speed drive, adjustable speed drive and etc. It

is one of the motor controllers which drive the AC electric motors by adjusting the frequency and voltage provided

to the motor. AC drives are providing in low, medium and high voltage.
Why People Use AC Motor Drives?
AC drives are of common use in various fields bringing people a lot of benefits. When it has been used on pump,

fan and other systems, it can help people save about 50% energy. Besides, the AC drive can enable people to achieve

precise process control and regulation, speed up or slow down a machine with smooth process and less wear. The

protection functions such as overcurrent, overload, short circuit, phase lose and others will protect the whole

control system from unnecessary faults. As it has obvious energy saving effect and perfect control accuracy, so the

AC drives are widely used in many fields.
Common Applications of AC Drives
The variable frequency drives are used in many areas such as elevators, construction elevators, ...
... tower cranes,

compressors, pumps, fans, solar system and so forth to reduce the energy consumption and enhance the process control

accuracy. Taking the application of AC drive in construction elevator control system for example, it can achieve

high control accuracy in the running speed, speeding up or slowing down process and leveling, so that the comfort

and safety will be greatly enhanced. By using an AC drive in the construction elevator control system, it is capable

of providing the system with complete protection as it is specially designed with RCD, special brake circuit design,

professional S curve speeding up and slowing down design and more functions.

By using an AC drive, it enables you to adjust the motor running speed with adjustable speed and saves about 40%

energy. Besides, the wear and tear of your machine and equipments will be reduce at a large amount, so it is without

saying that the life span of the motor and equipments will be extended and the mechanical maintenance cost will be

cut down also.
Leading Manufacturers of Suppliers of AC Drives
There are many companies manufacturing AC

drives such as Siemens (German), Hitachi (Japan), Fuji (Japan), Schneider (France), Veichi (China) and more.
