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.
Goodrive300 series VFDs 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.
