alternator stator assembly is a key component of the alternator, which is responsible for generating electrical power in the bus's charging system. The stator assembly plays a crucial role in converting mechanical energy from the engine into electrical energy.

Here is a description of the alternator stator assembly and its function:

1. Stator Core: The stator core is the stationary part of the alternator's rotor-stator system. It consists of a stack of laminated iron cores that form the foundation for the stator windings. The laminations help reduce energy loss due to eddy currents.

2. Stator Windings: The stator windings are a series of copper or aluminum conductive wires wound around the stator core. These windings are positioned in a specific configuration to create multiple sets of alternating magnetic poles when energized.

3. Pole Shoes: The stator windings are supported by pole shoes, which are iron or steel pieces mounted on the stator core. The pole shoes help concentrate and direct the magnetic flux generated by the stator windings.

4. Excitation Current: When an electrical current passes through the stator windings, it creates a magnetic field that rotates around the stator. This magnetic field induces a current in the rotor, which generates the necessary magnetic field for electricity generation.
