Description
Refer: Silicon Chip Magazine April/May 2012 (Revisions SC Aug 2013)

Control induction motors* up to 1.5kW (2HP) to run machinery at different speeds or controlling a pool pump to save money. Also works with 3-phase motors. Full form kit includes case, double-sided silk-screened PCB, heatsink, cooling fan, hardware and electronics (including parts from revised article in August 2013).

Features

Controls single-phase or 3-phase induction motors
Runs from a single-phase 230VAC, 10A power point
Over-current, over-temperature, under-voltage, over-voltage and short-circuit protection
EMI (electromagnetic interference) filtering for reduced radio interference
Inrush current limiting
Isolated control circuitry for safety
Mounted in an IP65 sealed enclosure
Adjustable speed ramp up/down
Pool pump mode
Can run 3-phase motors in either direction
Optional external speed control pot with run, reverse and emergency stop switches
Motor run/ramping and reverse indicator LEDs
Fault indicator LED
Open collector output provides either fault or up-to-speed indication

Specifications:

Motor power: up to 1.5kW (2 horsepower)
Maximum output voltage (single or 3-phase motor): ~230V RMS
Continuous output current: 8.5A RMS (single-phase), 5A RMS (3-phase)
Short term overload current: 13A RMS (single-phase), 7.5A RMS (3-phase)
Switching frequency: 16kHZ * Quiescent power: 28W
Speed ramp period adjustment: 3-30s to full speed
Continuous input current: up to 8.7A RMS
Speed control range: 1-100% or 1-150% (0.5Hz or 75Hz) in 0.05Hz steps
Efficiency: Up to 96%
Speed control signal: 0-3.3V
Up-to-speed/fault output sink: 12V/200mA

IMPORTANT NOTES:

This is an advanced project for an experienced constructor
*Project does not work for motors with centrifugal switch
