Series-excited motor is a kind of dual-use motor for AC and DC, which is mainly composed of three parts: stator, rotor and bracket. The stator consists of a convex pole core and an excitation winding

Universal Motor is a type of motor in which the stator coils (i.e. excitation windings) and the rotor coils (i.e. armature windings) are connected in series to the power supply through brushes and commutator.

Saixing motors are designed for quiet operation through proprietary motor design methods and material selection, which greatly reduces motor noise.
