What is a stator core?
The stator core is built up of thin punched laminations of electrical grade steel, which are commonly called “punchings.” They are segmented, meaning that 12 to 24 punchings are laid side-by-side to form a complete 360° ring, comprising one layer.
What is the purpose of a stator in an AC motor?
The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC). That current travels along fairly heavy gauge wire through the case and into the rectifier/regulator which converts it to DC power, and at a consistent output.
What is the difference between motor and rotor?
As nouns the difference between rotor and motor
is that rotor is a rotating part of a mechanical device, for example in an electric motor, generator, alternator or pump while motor is a machine or device that converts any form of energy into mechanical energy, or imparts motion.
What is the main function of rotor?
Rotors are the moving part in an Alternator that have permanent magnets that move around the Stator’s iron plates to generate an Alternating Current (AC). Rotors require existing motion to function, so only once the engine or turbine is already running will a Rotor work with a Stator to provide a charge.
What is the difference between rotor speed and synchronous speed?
The synchronous speed refers to the stator rotating magnetic field, which depends on the number of poles and frequency. The other speed is the rotor’s. The rotor speed will be always slower than the stator speed, we call it slip. … The induction motor must run at a speed below the revolving stator field flux.
