Overview
This reference design demonstrates the design of a 3-phase AC induction motor drive with volt per hertz control and supports the NXP® 56F80X and 56F83XX Digital Signal Controllers (DSCs) dedicated for motor control applications.
- Designed as a low-cost high volume motor drive system for medium power three-phase AC induction motors and is targeted for applications in both industrial and appliance fields
- The drive runs in a speed closed loop using a speed sensor
- According to the state of the control signals (Start/Stop switch, speed up/down buttons or PCMaster set speed) the speed command is calculated using an acceleration/deceleration ramp
