The frequency inverter is an electronic device whose main function is to transform the rotation of a three-phase motor by changing the frequency it provides at its output contacts. We can thus, toggle the speed with which the motor will work of easy form. The frequency supplied by the grid, which is the input frequency to the motor, determines the synchronous speed of the electric field through which the motor operates.
The inverter acts by changing this frequency at the motor input if the frequency is higher, consequently the motor speed s12-09a4-06 will be higher, and if the frequency is lower the speed is also lower. The use of a frequency inverter has a number of advantages, such as exploiting the operation of the motor and conditions not described in its construction characteristics. The use of the frequency inverter provides speed flexibility with safety and precision. It is possible to control the speed of the engine without extensive torque losses, smooth acceleration through programming, direct braking in the engine, no need for mechanical brakes, and various forms of speed programming according to the need of work.
