Choosing the right materials is critical when manufacturing small AC induction motors. The core components of a motor include the stator, rotor, and housing. The stator typically consists of laminated iron cores with copper windings wrapped around them; the rotor may feature a cast aluminum or squirrel cage structure. The selection of these materials not only influences the performance of the small AC induction motor but also determines its durability and cost.

The stator core is usually made of silicon steel sheets, which have great magnetic properties and help minimize eddy current losses. Copper windings serve as the path for current flow, and choosing high-purity copper helps reduce resistance and improve motor efficiency. For the rotor, a cast aluminum structure is preferred due to its good electrical conductivity and mechanical strength, especially in applications requiring frequent starts and stops.
