Excellent Control Performance under Speed Sensorless Vector
Control Mode
Realizing AC motor decoupling, enabling the DC motorization of operation control.
Fig. 1 indicates the four-quadrant operation of the motor under speed sensorless vector
control. The torque, current, speed and DC bus voltage have quick response, and the
motor has stable operation.
Realizing 0.1s acceleration/deceleration with rated motor load.
Upon the zero-crossing switching of the motor (forward/reverse switching), the current
has no phase mutation or oscillation, and the rotating speed has no pulsation.
The bus voltage is under stable control. Quick and reliable braking can be realized
when decelerating under the condition of braking without power consumption.
It is especially suitable for:
The reciprocating equipment, such as numerical control machine, fountain control
machine, weaving machine and jacquard.
