What is the internal principle of the motor?

 

Door Motors.jpgA motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is indicated by the letter M in the circuit. Its main function is to generate drive torque as a power source for electrical appliances or various machines. The generator is indicated by the letter G in the circuit. Its main role is to use electrical energy to convert into mechanical energy, which drives equipment such as pumps to operate.


The motor consists essentially of an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor and other accessories. Under the action of the rotating magnetic field of the stator winding, it has a current passing through the armature squirrel cage aluminum frame and is rotated by the action of the magnetic field.


A DC motor is a rotating electrical machine that converts DC electrical energy into mechanical energy or converts mechanical energy into DC electrical energy (DC generator). It is a motor that converts DC power and mechanical energy to each other. When it is used as a motor, it is a DC motor that converts electrical energy into mechanical energy; when the generator is running, it is a DC generator that converts mechanical energy into electrical energy.
