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

Features

• Speed Control of 3-phase AC Induction motor with quadrature volt per hertz control
• Targeted for 56F80X, 56F83XX, and 56F81XX Digital Signal Controllers
• Running on a High Voltage Medium Power Board for Three Phase Motors
• Volt-per-Hertz control with a speed closed loop
• Option to run the motor in open loop
• Quadrature encoder for motor speed reference
• Manual interface
• PC master software control interface and monitor
• Fault protection
