Explanation:
In a synchronous motor, various losses occur which need to be dissipated. The stator core surface plays a role in dissipating some of these losses. However, there is one particular loss that is not dissipated by the stator core surface, which is windage losses.
Eddy Current Losses in the Conductors:
Eddy current losses occur in the conductors of the stator due to the alternating magnetic field produced by the rotor. These losses result from the resistance of the conductors to the flow of current and are dissipated as heat. The stator core surface helps in dissipating these losses.
Iron Losses in the Stator:
Iron losses, also known as core losses, occur in the stator core due to the magnetic field variations. These losses consist of hysteresis losses and eddy current losses in the laminated core. The stator core surface provides a path for the dissipation of these losses.
Copper Losses in the Slot Portion of the Conductors:
Copper losses occur in the stator windings due to the resistance of the conductors. These losses result from the flow of current through the conductors and are dissipated as heat. The stator core surface aids in dissipating these losses.
Windage Losses:
Windage losses occur due to the friction and air resistance experienced by the rotating parts of the synchronous motor, such as the rotor. These losses are not related to the stator core surface and are not dissipated by it. Windage losses are typically dissipated through cooling mechanisms such as fans or ventilation systems.
Conclusion:
In a synchronous motor, the losses dissipated by the stator core surface include eddy current losses in the conductors, iron losses in the stator, and copper losses in the slot portion of the conductors. The loss not dissipated by the stator core surface is windage losses, which are related to the friction and air resistance of the rotating parts.
