Motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction, or converts one form of electrical energy into another form of electrical energy, and is commonly known as both a motor. Generator is the conversion of mechanical energy into electrical energy, its main role is to generate driving torque, as a power source for appliances or various machinery.
Motor and generator are the same.
1, the same structure, are composed of coils, magnets, commutators, brushes.
2, the components are connected in the same way, each component is connected in series to form a circuit.
3, are affected by the direction of the magnetic field, the direction of the current generated in the generator is related to the direction of the magnetic field; the direction of the force on the coil in the motor is related to the direction of the magnetic field.
Motor and generator different points.
1, the principle is different, the generator is made according to the electromagnetic induction phenomenon; the motor is made according to the principle of force movement of the energized conductor in the magnetic field.
2, the judgment method is different, the generator in the current direction judgment using the right-hand rule; motor in the direction of conductor movement using the left-hand rule.
3, the purpose of work and energy conversion is different, the generator requires external work to convert mechanical energy into electrical energy; motor external work to convert electrical energy into mechanical energy.
These are the definitions and differences between motors and generators. Only by mastering the knowledge of both can we better understand motors and generators.
