A burn-free motor comprises a motor, a junction box, a protective device, a motor stator, a plurality of groups of outer enameled coils and a plurality of groups of inner enameled coils, and is characterized in that the protective device is added in the junction box; At least one temperature control switch is arranged in the middle or cross part of a plurality of groups of outer enameled coils and a plurality of groups of inner enameled coils; The body of the protection device is made of insulating material, in which at least two safety tubes are arranged. One end of the wires at both ends of the safety tube comes from the power supply, and the other end leads to the inside of the motor. The protective device can be replaced by a magnetic switch. The utility model has the advantages of simple structure, novel shape, convenient disassembly, low cost and convenient use, and can be widely popularized and applied. Because the temperature control switch is arranged in the middle of the motor coil, when the coil temperature rises, the temperature control switch will automatically cut off the power supply, thus preventing the motor from burning out.
