# Induction generator from 4 hp induction motor

## Description

This is a Brook 4hp single phase capacitor start induction motor that is being excited by 4 capacitors which add up to 90 microfarad. The motor is also dual voltage 240/480 and is generating in 240v mode. The load is two halogen heaters which add up to 2900 watts. The motor has 4 poles and runs at 50 hz (1440 rpm). To generate it has to run at 2000 rpm plus or minus 50 rpm and then drops to 1700 rpm for most loads. At this speed it generates about 65 Hz, in 480 volt mode it generates 50 Hz under load. Changing capacitor size will alter what speed it will start to generate
