AC Motor control - Frequency converter
A complete installation with a frequency converter controlled motor consists of a series of different components which should all be selected carefully for a given application.
The components in an installation are selected according to the actual application, starting with selecting the right pump for the application. A suitable motor for the actual pump is chosen. The output filter of the frequency converter has to be able to handle the full load of the pump, and at the same time fit the frequency converter. The frequency converter should have the right power rating for the pump, and the fuses and the protective circuit breaker should fit the frequency converter. What follows is some information about how to choose the right components.
A frequency converter makes it possible to control the speed (rpm) of an asynchronous motor. This is done by controlling the output frequency to the motor.
Components in a typical installation
A standard frequency converter is shown to the right, the power-handling sub- circuits are:
-
-
- Input filter
- Rectifier
- Energy storage circuit or Intermediate circuit
- Inverter
-
The function of the different components in the sub circuit is:

Motor Control circuits - Exercise 082
Motor 1 and motor 2 are run one by one, controlled from the same circuit.
When motor 1 is turned on, motor 2 is off, and can not be turn on.
Same when motor number 2 is on, motor 1 is off and can not be turn on.
