Overview:
1. The air gap between the stator and rotor of the motor is very small, which easily causes the stator and rotor to collide in medium and small motors. The air gap is generally 0.2mm ~ 1.5mm.When the air gap is large, the excitation current is required to be large, which affects the power factor of the motor; if the air gap is too small, the rotor may cause...
