Brief description of the working principle of dc motor
There is a magnetic field present inside the motor, and the current-carrying rotor (i.e., armature) conductor will be subjected to an electromagnetic force, f, f=Blia (left-hand rule).
The electromagnetic force generated by all the conductors acts on the rotor, causing it to rotate at n (revolutions per minute) in order to make drag a mechanical load. A DC motor is an electric motor that converts DC electrical energy into mechanical energy.
Because of its good speed regulation performance and widely used in power drag. DC motor according to the excitation method is divided into permanent magnet, other excitation and self-excitation of three categories, of which self-excitation is divided into parallel excitation, series excitation and re-excitation of three kinds.
