engineering recuitment NHPC JE & THDC JE 2023 Mock Test Electrical Machines Alternator and Synchronous Motors
An ideal synchronous motor has no starting torque because the
1
Rotor is made up of salient poles.
2
Relative velocity between the stator and rotor mmfs is zero.
3
Relative velocity between stator and rotor mmfs is not zero.
4
Rotor winding is highly inductive.
