Abstract
A cutting machine includes a cutting element for cutting material, a motor for driving the cutting element to rotate and a housing for containing the motor. The motor includes a rotor sleeve being formed with a receiving chamber, a motor shaft being capable of rotating together with the rotor sleeve, a stator core at least partially contained in the receiving chamber, stator coils wound around the stator core, and a stator bracket for fixing the stator core. The stator core is formed with a through hole for the motor shaft to pass there through, the stator coils are located outside the through hole and, the motor shaft is capable of rotating relative to the stator core.
