Description
Technical field
The utility model is related to motors, and in particular to thermal protection device of motor.
Background technology
It is well known that motor improves the production efficiency of the mankind, however, working as motor running hours, motor can generate heat, and
The motor of overheat can break down, and need making time and at original repair.
Invention content
The purpose of this utility model is：A kind of thermal protection device of motor is designed, motor is protected when motor overheating or overcurrent,
Avoid unnecessary repair.
The technical solution of the utility model is：The thermal protection device of motor includes thermistor, thermistor insertion
In the enameled wire of motor, the single line of thermistor is connect with motor lines, and the another single line of thermistor is connect with enameled wire, heat
Quick resistance is connected in circuit.
When motor continuous work, the motor feels hot when being more than the temperature of thermistor setting, and thermoswitch disconnects, motor not work
Play the role of protecting motor；When electrical-coil electric current is more than the electric current of thermistor setting, thermoswitch disconnects, motor not work
Play the role of double protection motors.
The utility model has the advantages that：It is simple in structure, it is of low cost, the sky of thermistor is installed in coil internal economies
Between, thermistor is connected in the line, and double protection motors are played the role of.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1 motor, 2 enameled wires, 3 thermistors.
Specific implementation mode
As shown in Figure 1, the thermal protection device of motor includes thermistor 3, thermistor 3 is embedded in the enameled wire 2 of motor 1
In, 3 single line of thermistor is connect with motor lines, and 3 another single line of thermistor is connect with enameled wire, and thermistor 3 is connected on
In circuit.
When 1 continuous work of motor, the motor feels hot be more than thermistor 3 set temperature when, thermoswitch disconnect, motor 1
It does not work and plays the role of protecting motor；When electrical-coil electric current is more than 3 setting electric current of thermistor, thermoswitch disconnects, motor 1
It does not work and plays the role of double protection motors.
