CUThe bars and end-rings in the rotor are made from copper to ensure high motor efficiency. This also allows for decreased vibrations from rotation as the shaft is thicker than those used in aluminum rotors.
ALThe bars and end-rings in the rotor are made from aluminum which provides an excellent balance between price and performance.
LDThis stator is dipped into the insulation vanish. It is our most common model which is suitable to general spindle motors.
HDThis copper coil of the stator is filled with special resin which helps to decrease the temperature of coils.
