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.
Goodrive200 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.
