A precious metal brushed DC motor is a DC motor that uses brushes made of precious metal materials (such as palladium, rhodium, iridium, etc.). This kind of motor is usually used in situations that require high motor performance, such as aerospace, medical equipment, precision instruments, etc. The XBD-1718 precious metal brushes have good electrical conductivity and wear resistance, and can maintain stable working performance in harsh environments such as high speed, high temperature, and high humidity.
