- Synchronous motors have their pole-shoes slotted for placing copper bars. The copper bars are placed in these slots and short-circuited at both ends by heavy copper rings (like squirrel cage rotor of induction motors). This arrangement is known as damper winding in synchronous motor.Learn more:Synchronous motors have their pole-shoes slotted for placing copper bars.
