Title: Drive control equipment for induction motor
Inventor: HARADA HIDENORI
IPC: H02P27/06
Filed: 1993-10-08
Abstract: PURPOSE:To improve efficiency by obtaining through frequency command value arithmetic operation an exciting current amplitude and a phase calculation that maximize the efficiency of an induction motor, and commanding an output voltage and a phase value that cope with a specific load torque with high effi ciency. CONSTITUTION:First, a loop of control values is established for plant amounts to control, such as the pressure, temperature, flow rate, number of revolutions, speed and so on. Then a frequency command value for an inverter is calculated from the control values in the control loop using a control arithmetic operation means. Meanwhile, the effective values and phase of the voltage and current of distorted waves supplied from the inverter to an induction motor, is measured to calculate the circuit constant of the induction motor. The load torque of the induction motor at that time is calculated from the circuit constant to obtain an exciting current amplitude and a phase calculation in terms of effective value that maximize the efficiency of the induction motor. An output voltage command value and a phase value, based on the result of the calculation, that cope with a specific load torquue, is commanded to the inverter. This will improve functions without degrading.
