Title: Speed controller of induction motor
Inventor: MASAKI TAKANOBU
IPC: H02P27/04
Filed: 1984-03-19
Abstract: PURPOSE:To generate a stable motor torque by decreasing an exciting current component command value in response to the decrease in the voltage of a power source or the input voltage of an inverter, thereby obtaining the margin of the output voltage of the inverter to reliably control a vector. CONSTITUTION:A converter output voltage Vdc is detected by a voltage detector 111. If the voltage Vdc is low, an exciting current component command value 112a is limited to a low value. Accordingly, since the primary voltage command values 30a-30c may be low value, a voltage necessary to flow an exciting current component signal in response to the value 112a can be obtained even if the output voltage Vdc decreases, thereby preferably controlling a vector.
