7.3 Vector control
Because asynchronous motors have the characteristics of high stage,
nonlinear, strong
coupling and various variables, the actual control of the asynchronous motor is very difficult.
Vector control is mainly used to settle this problem with the theme of that divide the stator
current vector into exciting current (the current heft generating internal magnetic field of the
motor) and torque current (the current heft generating torque) by controlling and measuring
the stator current vector according to the principles of beamed magnetic field to control the
range and phase of these two hefts. This method can realize the decoupling of exciting
current and torque current to adjust the high performance of asynchronous motors.
Goodrive200A series inverters are embedded speedless sensor vector control calculation
for driving both asynchronous motors and synchronous motors. Because the core
calculation of vector control is based on exact motor parameter models, the accuracy of
motor parameter will impact on the performance of vector control. It is recommended to input
the motor parameters and carry out autotune before vector running.
Because the vector control calculation is vary complicated, high technical theory is needed
for the user during internal autotune. It is recommended to use the specific function
parameters in vector control with cautions.
