Single and multi-phase AC induction motor control using the PIC16F1509 microcontroller
This application note from Microchip provides a detailed analysis of driving a single and multi-phase AC induction motor using the 8-bit PIC microcontrollers. It shows how to build a low-cost three-phase inverter circuit using PIC16F1509 to add speed control and soft-start to a single and multi-phase AC induction motor.
