Sistema de controle para motores elétricos |
摘要 |
An electric power controller (8) for use with AC induction motors (9) that measures line voltage and current phase angles, and uses a microprocessor (10) to calculate delay values for firing silicon control rectifier (SCR) gates (76) to provide efficient amounts of current to the motors (9). The calculation is made using the measured phase angles, an inputted measured full load power factor for each motor, and corrected power factor value stored in a read-only-memory (ROM). |
