A slip ring, commonly known as a conductive slip ring, is formed by the friction between the rotor and the stator to rotate the joint. The motor slip ring is also one of them. The motor slip ring mainly converts electrical energy, so that the current is converted into electrical energy through rotating sliding contact.

Motor is commonly known as "motor", which refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The main function of the motor in the circuit is to generate driving torque. As a power source for electrical appliances or various machines, the main function of the generator is to convert mechanical energy into electrical energy.

The principle of motor power generation: After the wire is cut by the magnetic field, a current is generated in the wire. The generator cuts the wire by rotating the magnetic field. The rotating magnetic field is the rotor, and the cut wire is the stator. In order for the rotor to generate a magnetic field, a magnetizing current must be input to the rotor coil. Since the rotor is rotating, the excitation current is transmitted to the excitation winding of the rotor through the contact of the carbon brush and the slip ring.

The motor slip ring plays the role of input/output current and commutation in the motor. The wear resistance of the motor slip ring directly affects the service life of the motor. The motor slip ring leads the rotor coil to the outside, which is convenient for measuring the rotor current and controlling the motor. speed.
