Synchronous Motors   QTY 19

Synchronous Motors
An AC synchronous motor is designed to run at a fixed RPM related to the AC line frequency and is commonly used where precise constant speed is required. They will run at constant locked-in speed until it becomes overloaded at which point, it stalls out. Once the excessive load is removed, it can restart and go back to its synched speed of rotation.
