The stator is the component of a rotating system that remains stationary, and it is often used in generators, motors, alarms, mud engines, and other machinery and equipment. The stator can act as a magnet that interacts with the rotor to produce motion, and interacts with the armature to produce motion. It can also act as an armature working with a moving magnetic field coil in the rotor. The motor stator can be made of iron, steel or printed circuit board (PCB). PCB stators can be lighter, smaller, and less noisy than other stators.
The stator in an AC motor usually consists of a thin steel core and insulated coils inserted into it, which combine to form an excitation winding that becomes an electromagnet when the current is turned on. In a DC motor, the stator carries the excitation winding and poles, which form a magnetic circuit with the rotor.
The stator is an important part of the motor and remains stationary at all times, whether the rotor is rotating around it or inside it.
