6.Difference between SMX and conventional inverter
Conventional inverter aims to determine the voltage (V / F characteristics)
by changing the motor frequency, thus to control rotating speed and
torque.These are basic functions of SMX. Voltage provided by conventional
inverter is unrelated to motor load. It is shown from characteristics of motor:
the voltage supplied to the motor is positively related to power consumption.
When the voltage supplied to the motor is too low, the motor will not work
properly due to lower torque. Therefore, a conventional inverter runs at higher
voltage for normal operation, thereby preventing adverse impact from lower
voltage, resulting in waste of energy.
