The series-excited motor is mainly composed of a stator, a rotor, a front and a rear cover (cover) and a heat-dissipating fan blade. The stator is composed of a stator core and a winding sleeved on the pole piece, and the function is to generate a field magnetic flux, a magnetic flux and Supporting the front and rear covers; the rotor is composed of a rotor core, a shaft, an armature winding and a commutator, and its function is to ensure and generate a continuous electromagnetic moment.
And the work is carried out by the rotating shaft to convert the electric energy into mechanical energy; the front and rear covers support the armature The fixed shaft and the rotor are fixed and integrated into one body. The rotating shaft, the front and rear covers must have sufficient strength to prevent the armature from resonating with the cover, causing vibration and danger. Generally, there are rolling or sliding in the front and rear covers.
