This whitepaper provides background on three-phase AC motors and inverters, and what to consider when specifying a motor and inverter pair for optimal performance.
This chapter aims to bring a detailed analysis of the specific design aspects of inverters for advanced three-phase electric motors, which require a high degree of precision in their control to
In order to control the output voltage supplied to a motor, the DC voltage fed to the inverter is varied by a voltage booster. To rotate a motor at low RPM, the DC voltage is set to a relatively low voltage (for
Freely Set and Change AC Power Frequency and Voltage. An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely
By adjusting the frequency and voltage supplied to an AC motor, frequency inverters provide significant advantages in energy efficiency, motor performance, and operational flexibility.
Variable voltage variable frequency supply to the motor is obtained within the Inverter Control itself using suitable control based on the principles of PWM or PSM (phase shift modulation). The block diagram
