Lucas -TVS Rotor

Rotor used in alternator performs the function similar to that of field coil in case of dynamos. When a small field current is passed through the coir via the slip rings, a magnetic field is generated around the rotor. In the process of rotation of the rotor, the magnetic field is cut by the stator winding and an e.m.f. is generated in the stator windings. The output of the alternator is dependent on the number claws of the rotor, strength of the field current, quality of the conductor used etc.

In order to get the best performance and life, the rotor should have the following characteristics.

  • excellent conductivity of the rotor coil wire.
  • excellent insulation between rotor coil & rotor claws.
  • Rotor should be dynamically balanced to prevent vibration and consequential bearing failures.
  • accurate dimensions of claws and rotor coil to ensure the air gap between the claws and rotor coil is uniform through out.
