The Advantage Of DC Motor
DC motor is a type of motor that converts electrical energy into mechanical energy, and its working principle is based on electromagnetic induction and Lorentz force. A DC motor consists of a stator and a rotor, with the stator stationary and the rotor rotatable.
In a DC motor, there is a set of coils on the stator, called excitation coils, which are connected to the power supply to generate a combustion field. There is also a set of coils on the rotor, called armature coils, which are connected to the power supply to generate current. When the current passes through the central coil, it generates a magnetic field that interacts with the magnetic field of the excitation coil, generating a torque that causes the rotor to start rotating.
When the rotor rotates, the direction of the current in the armature coil will change accordingly, which will cause the direction of the magnetic field to also change. Due to the Lorentz force, this changing magnetic field will generate a reverse torque, causing the rotor to slow down and ultimately stop rotating. In order to maintain the motion of the rotor, it is necessary to continuously change the direction of the current in the armature coil, which is called commutation.
Reversing can be achieved through mechanical brushes and electronic transducers. Mechanical brushes are a set of carbon brushes whose contact points with the armature coil constantly change with the rotation of the rotor, thereby changing the direction of the current. An electronic commutator is an electronic device that controls the direction of current based on the position and speed of the rotor, thereby achieving commutation.
