Stator - Wikipedia

The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors or biological rotors.Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to ...

Capacitor start electric motors use a starting coil and a capacitor to create an advancing magnetic field in the stator (outer frame of the motor with its coils). This advancing magnetic field gives the rotor something to chase, causing the rotor to spin. (For example, put a bar magnet on top of a glass table.

Electric motor - Wikipedia

An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles ...

Potting (electronics) - Wikipedia

In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for high voltage assemblies by excluding gaseous phenomena such as corona discharge, for resistance to shock and vibration, and for the exclusion of water, moisture, or corrosive agents. Thermosetting plastics or silicone rubber gels are often used, though epoxy resins are also ...

Electric motor - Construction of induction motors | Britannica

Electric motor - Electric motor - Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
