Inverter Motor Speed Control

A basic vfd system generally consists of an ac motor a controller and an operator interface.

Vfd is shorted for variable frequency drive also known as ac drives and inverters that s used to make an ac motor working in variable speed among other parameters this is definition used in all topical discussion on this paper. See the 220v vfd inverter buying li. Ac motor main drive controller assembly and drive operator interface.

The inverter outputs a pulsed voltage and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor. A variable frequency drive vfd is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. The ac electric motor used in a vfd system is usually a three phase induction motor some types of single phase motors or synchronous motors can be advantageous in some situations but. How an inverter drive works and controls the speed of an ac induction motor an inverter drive vfd works by taking ac mains single or three phase and first rectifying it into dc the dc is usually smoothed with capacitors and often a dc choke before it is connected to a network of power transistors to turn it into three phases for the.

The inverter first converts the input ac power to dc power and again creates ac power from the converted dc power using pwm control. Frequency or hertz is directly related to the motor s speed rpms. By using the flux vector controlled vfd it will improve the deficiency of motor torque at low speed or even in the low speed region the motor can output enough torque. Other names for a vfd are variable speed drive adjustable speed drive adjustable frequency drive ac drive microdrive and inverter.

Maybe you have walked past without noticing them or maybe you know exactly how many you have either way electric motors play an important role in our everyday lives which most of us are unaware of but they move and run most things we need for business and pleasure.
