3 Phase Motor Startups, No soft startup, Compilation #3 Across The Line

Описание к видео 3 Phase Motor Startups, No soft startup, Compilation #3 Across The Line

You guys asked for it, Round 3! Various motor startups, including a 800 horsepower chiller on 4160 VOLTS.
3 phase motors pull a large amount of current on startups (6-10x the Full Load Current) which causes the windings of the motor to vibrate with each other and that vibration is the sound you hear while it starts up.
Most of these motors is on Air handlers with squirrel cage fans, or pumps and more!
Hope you enjoy round 3! More coming as I gather more!
